lnmp搭建-手动版

参照链接：http://blog.csdn.net/bravemelon/article/details/64925499

centOS  下安装 Nginx

yum -y groupinstall "Development Tools"
yum -y install wget
yum install gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
yum -y install make gcc gcc-c++ gcc-g77 flex bison file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel libpng10 libpng10-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glib2 glib2-devel bzip2 bzip2-devel libevent libevent-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel gettext gettext-devel ncurses-devel gmp-devel pspell-devel unzip libcap lsof

.直接下载.tar.gz安装包，地址：https://nginx.org/en/download.html

.使用wget命令下载（推荐）。

wget -c https://nginx.org/download/nginx-1.10.1.tar.gz

解压

依然是直接命令：

tar -zxvf nginx-1.10..tar.gz
cd nginx-1.10.

配置

.使用默认配置(推荐)

./configure

.自定义配置（不推荐）

./configure \
--prefix=/usr/local/nginx \
--conf-path=/usr/local/nginx/conf/nginx.conf \
--pid-path=/usr/local/nginx/conf/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/temp/nginx/client \
--http-proxy-temp-path=/var/temp/nginx/proxy \
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
--http-scgi-temp-path=/var/temp/nginx/scgi

注：将临时文件目录指定为/var/temp/nginx，需要在/var下创建temp及nginx目录

编译安装

make
make install

查找安装路径：

whereis nginx

启动、停止nginx

cd /usr/local/nginx/sbin/
./nginx 

[root@ecs---jenjins sbin]# ./nginx
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] bind() to 0.0.0.0: failed (: Address already in use)
nginx: [emerg] still could not bind()

问题描述：地址已被使用。可能nginx服务卡死了，导致端口占用，出现此错误。

解决：
kill -
kill -
或者 killall - nginx

从新载入配置文件启动 /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

二、修改配置文件

、以下的配置文件没用的都删除

[root@ecs---jenjins conf]# cat nginx.conf

#user  nobody;
worker_processes  ;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  ;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  ;
    keepalive_timeout  ;

    #gzip  on;

    server {
        listen       ;
        server_name  www.jenjins_1.com;
        access_log  logs/hongfa1.access.log  main;
        location / {
            root   /web/hongfa1;
            index  index.html index.htm;
        }
    }

    server {
        listen       ;
        server_name  www.jenjins_2.com;
        access_log  logs/hongfa3.access.log  main;
        location / {
            root   /web/hongfa3;
            index  index.html index.htm;
        }
    }

    server {
        listen       ;
        server_name  www.jenjins_3.com;
        access_log  logs/hongfa3.access.log  main;
        location / {
            root   /web/hongfa5;
            index  index.html index.htm;
        }
    }

}

、没有搭建本地DNS，就配置hosts解析文件，都是一样的效果

[root@ecs---jenjins ~]# cat /etc/hosts
127.0.0.1 ecs---jenjins
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1       localhost
117.78.44.225   www.jenjins_1.com
117.78.44.225   www.jenjins_2.com
117.78.44.225   www.jenjins_3.com
117.78.44.225   www.jenjins_4.com

、配置html虚拟机文件

在根目录下创建这几个文件
/web/hongfa4/index.html         hongfa4
/web/hongfa5/index.html             <h1>www.hongfa2.com</h1>
/web/hongfa1/index.html         <h1>www.hongfa1.com</h>
/web/hongfa3/index.html             <h1>www.hongfa3.com</h1>

、设置防火墙，把80端口映射到 ,,  ，8080不能用，因为nginx首页已经占用，而80    端口要占一个，

[root@localhost ]# /sbin/iptables -I INPUT -p tcp --dport  -j ACCEPT      这句话非常重要，下面两句可以不执行，要多执行几次
[root@localhost ]# /etc/init.d/iptables save
[root@localhost ]# /etc/init.d/iptables restart               ---如果不行，用下面的。
[root@ecs---jenjins hongfa1]# systemctl restart firewalld

至此，主机已可访问虚拟机的nginx服务。

下面可以不执行，好像是，不能访问，执行试试，也可以写到iptables配置文件里

iptables -A INPUT -p tcp -m tcp --dport  -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport  -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport  -j ACCEPT

、开始访问

5.1  http://117.78.44.225:80

www.hongfa1.com

5.2  http://117.78.44.225:8081

hongfa4 

5.3  http://117.78.44.225:8083

www.hongfa2.com

5.4  http://117.78.44.225:8084

www.hongfa3.com

三、搭建mysql

http://www.jianshu.com/p/95a103add722

Centos 7.2 编译安装 MySQL 5.7.

一、环境准备
、查看系统版本

[root@lnmp ~]# cat /etc/redhat-release
CentOS Linux release 7.2. (Core)
[root@lnmp ~]# uname -r
3.10.-327.28..el7.x86_64

、卸载系统自带的mysql/mariadb数据库及boost旧版本
复制代码
rpm -qa | grep mysql
rpm -qa | grep mariadb
rpm -e --nodeps boost-system-1.53.-.el7.x86_64
rpm -e --nodeps boost-thread-1.53.-.el7.x86_64
rpm -e mariadb-libs-5.5.-.el7_2.x86_64
rpm -e --nodeps mariadb-libs-5.5.-.el7_2.x86_64
boost官网http://www.boost.org/ ，yum -y install boost boost-devel boost-doc安装的是boost1.53版本

、准备安装文件
复制代码
[root@lnmp mysql]# ll
total
drwx------    games      Aug  : boost_1_59_0
-rw-r--r--   root root   Aug    boost_1_59_0.tar.gz
drwxr-xr-x         Aug  : mysql-5.7.
-rw-r--r--   root root   Aug  : mysql-5.7..tar.gz

说明：mysql5.7系列指定boost版本为boost_1_59_0。
资源下载地址：
[root@snails ~]# wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz
[root@snails ~]# wget http://cdn.mysql.com/Downloads/MySQL-5.7/mysql-5.7.13.tar.gz

、依赖包安装
yum -y install make gcc-c++ cmake bison-devel ncurses-devel libaio libaio-devel perl-Data-Dumper net-tools

二、安装boost/mysql
、安装boost
 tar xvf boost_1_59_0
 cd boost_1_59_0
 ./bootstrap.sh --with-libraries=system,filesystem,log,thread --with-toolset=gcc
 ./b2 toolset=gcc cxxflags="-std=c++11"
 ./b2 install --prefix=/usr/local/boost
#备注：上面红色字体的内容，参考如下配置；上面绿色字体内容代表使用c++11标准，编译的库要使用统一标准。不使用，去掉绿色字体内容。

#默认安装在/usr/local/lib目录下;头文件在/usr/local/include/boost目录下；install后面可以加参数 --prefix=/usr 来设置安装路径
#如果提示boost版本不对应则卸载boost安装对应版本boost

新建MySQL用户和用户组

[root@snails ~]# groupadd -r mysql && useradd -r -g mysql -s /sbin/nologin -M mysql

预编译

[root@snails ~]# tar -zxvf boost_1_59_0.tar.gz

[root@snails data]# md5sum mysql-5.7..tar.gz 

8fab75dbcafcd1374d07796bff88ae00  mysql-5.7..tar.gz

[root@snails ~]# tar -zxvf mysql-5.7..tar.gz

[root@snails data]# mkdir -p /data/mysql

[root@snails data]# cd mysql-5.7.

[root@snails data]# cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_DATADIR=/data/mysql \
-DWITH_BOOST=../boost_1_59_0 \
-DSYSCONFDIR=/etc \
-DWITH_INNOBASE_STORAGE_ENGINE= \
-DWITH_PARTITION_STORAGE_ENGINE= \
-DWITH_FEDERATED_STORAGE_ENGINE= \
-DWITH_BLACKHOLE_STORAGE_ENGINE= \
-DWITH_MYISAM_STORAGE_ENGINE= \
-DENABLED_LOCAL_INFILE= \
-DENABLE_DTRACE= \
-DDEFAULT_CHARSET=utf8mb4 \
-DDEFAULT_COLLATION=utf8mb4_general_ci \
-DWITH_EMBEDDED_SERVER=

编译安装

[root@snails mysql-5.7.]# make -j `grep processor /proc/cpuinfo | wc -l`
#编译很消耗系统资源，小内存可能编译通不过make install

[root@snails mysql-5.7.]# make install

三、配置mysql
、创建用户，初始化数据库　
groupadd mysql
useradd -g mysql -s /sbin/nologin mysql

、授权mysql数据库目录
chown -R mysql:mysql /usr/local/mysql

、初始化mysql数据库
/usr/local/mysql/bin/mysqld \
--initialize \
--user=mysql \
--datadir=/usr/local/mysql/data/

、拷贝配置文件,修改配置文件
复制代码,按照下面的修改一下，修改之后无法加载配置文件，没关系，可能编译有问题
  cp support-files/my-default.cnf /etc/my.cnf
  [root@lnmp ~]# cat /etc/my.cnf
  # For advice on how to change settings please see
  # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
  # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
  # *** default location during install, and will be replaced if you
  # *** upgrade to a newer version of MySQL.
  [mysqld]
  # Remove leading # and set to the amount of RAM for the most important data
 # cache in MySQL. Start at % of total RAM for dedicated server, else %.
 # innodb_buffer_pool_size = 128M
 character_set_server=utf8
 init_connect='SET NAMES utf8'
 #skip-grant-tables
 # Remove leading # to turn on a very important data integrity option: logging
 # changes to the binary log between backups.
 # log_bin
 # These are commonly set, remove the # and set as required.
 # basedir = .....
 #datadir =  /usr/local/mysql/data
 # port = .....
 # server_id = .....
 # socket = .....
 # Remove leading # to set options mainly useful for reporting servers.
 # The server defaults are faster for transactions and fast SELECTs.
 # Adjust sizes as needed, experiment to find the optimal values.
 # join_buffer_size = 128M
 # sort_buffer_size = 2M
 # read_rnd_buffer_size = 2M
 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
 [client]
 default-character-set=utf8
复制代码

root@ecs---jenjins www.test.com]# source /etc/my.cnf  -------------没关系，没有影响
bash: [mysqld]: command not found...

、拷贝启动文件，并授权
、cp support-files/mysql.server /etc/init.d/mysqld
、chmod  /etc/init.d/mysqld

 、启动数据库
　　
/etc/init.d/mysqld start

三、更改初始化生成的数据库密码
注：由于5.7版本会初始化设置密码，需要自己修改，跟之前的数据库版本更改方式不一样。
完整的更改MySQL密码的方式如下：

vim /etc/my.cnf 加入skip-grant-tables，免密码登录数据库

[root@ecs---jenjins mysql-5.6.]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at % of total RAM for dedicated server, else %.
# innodb_buffer_pool_size = 128M
character_set_server=utf8
init_connect='SET NAMES utf8'
skip-grant-tables                                                                 -------------加上这句话，免密登陆，登陆完再删掉。
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....

# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M 

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[client]
default-character-set=utf8

重启MySQL数据库
[root@lnmp ~]# /etc/init.d/mysqld restart    ----------或者service mysqld start
Shutting down MySQL.. SUCCESS!
Starting MySQL. SUCCESS! 

登录数据，修改密码即可，注5.7的password字段改为authentication_string
MySQL
update mysql.user set authentication_string=password('pwd123') where user='root' ;

改完后，注释掉my.cnf里面的skip-grant-tables 这一行，重启MySQL登录验证即可，然后就可以登录数据库进行一些简单的操作了。

[root@lnmp ~]# mysql -uroot -p

mysql> grant all privileges on *.* to 'root'@'%' identified by 'pwd123';
Query OK,  rows affected (0.00 sec)
mysql> flush privileges;
Query OK,  rows affected (0.00 sec)

四、安装php7

Centos7 安装 PHP7最新版的详细教程

http://www.jb51.net/article/109228.htm

方法一、简单安装（通过yum）

.安装epel-release

rpm -ivh http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

.安装PHP7的rpm源

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

.安装PHP7

yum install php70w

放法二、编译安装

.下载php7

wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.1.tar.gz/from/this/mirror

.解压php7

tar -xvf php7.tar.gz

.进入php目录
cd php-7.1./

.安装依赖包

yum install epel-release gcc gcc-c++ libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel -y

.编译配置（如果出现错误，基本都是上一步的依赖文件没有安装所致）

编译前做一下这些，防止出错
[root@ecs---jenjins ~]# cd /usr/local/
[root@ecs---jenjins local]# mkdir php
[root@ecs---jenjins ]# mount
[root@ecs---jenjins ]# umount /run/user//gvfs

--with-xsl \
--enable-zip \
--enable-mysqlnd-compression-support \
--with-pear \
--enable-opcache

.正式安装

make && make install

编译最后出现错误：collect2: error: ld returned  exit status

解决：
[root@ecs---jenjins php-7.1.]# make ZEND_EXTRA_LIBS='-liconv'
[root@ecs---jenjins php-7.1.]# ln -s /usr/local/lib/libiconv.so. /usr/lib64/
[root@ecs---jenjins php-7.1.]# make && make install

.配置环境变量

vi /etc/profile

在末尾追加
export PATH=$PATH:/usr/local/php/bin

执行命令使得改动立即生效
source /etc/profile

sed -i '$a\export PATH=$PATH:/usr/local/php/bin' /etc/profile && source /etc/profile

.配置php-fpm

cp /usr/local/php-7.1./php.ini-production /etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

如果报错按照下面做

[root@ecs---jenjins ~]# find / -name php-fpm.conf.default
find: ‘/run/user//gvfs’: Permission denied
[root@ecs---jenjins ]# mount     看最后一行
[root@ecs---jenjins ]# umount /run/user//gvfs

cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
cp /usr/local/php-7.1./sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm

.启动php-fpm

/etc/init.d/php-fpm start

错误：
Starting php-fpm [-Aug- ::] ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address 

already in use ()
[-Aug- ::] ERROR: FPM initialization failed
 failed

解决方法：

netstat -lntup | grep 

killall php-fpm

[root@www ~]# service php-fpm start
Starting php-fpm  done                            启动成功

下面的错误不用管，没有影响
[root@ecs---jenjins www.test.com]# source /etc/php.ini     -----------------不用管，没有影响
bash: [PHP]: command not found...
-bash: /etc/php.ini: line : syntax error near unexpected token `;;'
-bash: /etc/php.ini: line : `;;;;;;;;;;;;;;;;;;;'

五、测试访问

[root@localhost ]# /sbin/iptables -I INPUT -p tcp --dport  -j ACCEPT -----------------无法访问就执行这句话
root@localhost ]# /etc/init.d/iptables save
[root@localhost ]# /etc/init.d/iptables restart
[root@ecs---jenjins hongfa1]# systemctl restart firewalld

一、全部删了配置文件，赋值下面的。
root@ecs---jenjins html]# cat /usr/local/nginx/conf/nginx.conf
user root root;
worker_processes  ;
events {
    worker_connections  ;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

server {
    listen ;
    server_name www.test.com;
    charset    utf-;
    location / {
    root /var/www/www.test.com;
        index index.php index.html index.htm;
        }

        location ~ \.php$ {
        root html;
            fastcgi_pass 127.0.0.1:;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /var/www/www.test.com$fastcgi_script_name;
            include fastcgi_params;
        }
    }

}

[root@ecs---jenjins ~]# mkdir -p /var/www/www.test.com/
[root@ecs---jenjins ~]# cd /var/www/www.test.com/
[root@ecs---jenjins ~]#touch index.php
[root@ecs---jenjins ~]#vi index.php

<?php
phpinfo();
?>

[root@ecs---jenjins www.test.com]# chown -R  /var/www/www.test.com/

[root@ecs---jenjins www.test.com]# vi /etc/hosts

127.0.0.1 ecs---jenjins
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::         localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1       localhost
117.78.44.225    www.test.com

[root@ecs---jenjins www.test.com]# curl http://117.78.44.225/index.php

二、测试mysql连接是否成功

[root@ecs---jenjins ~]# cd /var/www/www.test.com/
[root@ecs---jenjins ~]#touch index.php
[root@ecs---jenjins ~]#vi index.php

[root@ecs---jenjins www.test.com]# cat index.php
<?php
       $conn=mysqli_connect("127.0.0.1","root","");
       if($conn){
         echo "连接mysql数据库成功";
       }else{
          echo "连接数据库失败";
       }
?>

[root@ecs---jenjins www.test.com]# curl http://117.78.44.225/index.php
连接mysql数据库成功

报错：

原因：   centos php7怎么添加mysql支持

php7可以通过pod_mysql或者mysqli来开启mysql的支持php5中mysql扩展，在php7中已经不支持了。

一、正确做法

<?php
       $conn=mysqli_connect("127.0.0.1","root","pwd123");    注意mysqli_connect   多个i
       if($conn){
         echo "连接mysql数据库成功";
       }else{
          echo "连接数据库失败";
       }
?>

错误的

<?php
       $conn=mysql_connect("127.0.0.1","root","pwd123");    注意mysql_connect   少个i
       if($conn){
         echo "连接mysql数据库成功";
       }else{
          echo "连接数据库失败";
       }
?>

六：上传web网站
