第一步安装nginx1.10.3

优化nginx的介绍:jemalloc
https://ideas.spkcn.com/software/os/linux/577.html
预先安装autoconf 和 make
yum -y install autoconf make
jemalloc的安装
jiemalloc 开源项目网站 http://www.canonware.com/jemalloc/
wget https://github.com/jemalloc/jemalloc/releases/jemalloc-4.2.1.tar.bz2
tar -xjf jemalloc-4.2..tar.bz2
cd jemalloc-4.2.
./configure --prefix=/usr/local/jemalloc --libdir=/usr/local/lib
make && make install
make clean
cd ../
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig 使用jemalloc优化MYSQL数据库
MYSQL或者MariaDB源码编译时添加以下参数
-DCMAKE_EXE_LINKER_FLAGS="-ljemalloc" -DWITH_SAFEMALLOC=OFF
或者编辑mysqld_safe文件直接加载:
查找文件 /usr/local/mysql/bin/mysqld_safe
在# executing mysqld_safe 下面加上 LD_PRELOAD=/usr/local/lib/libjemalloc.so
重新启动MYSQL 使用下面代码自动修改mysqld_safe文件
sed -i 's@executing mysqld_safe@executing mysqld_safe\nexport LD_PRELOAD=/usr/local/lib/libjemalloc.so@' /usr/local/mysql/bin/mysqld_safe service mysqld restart
使用jemalloc优化NGINX
编译NGINX时添加以下参数:
--with-ld-opt="-ljemalloc" 验证 jemalloc 是否运行:
lsof -n | grep jemalloc

这个配置稍后在lnmp第二部分,此处没有mysqld的优化。
nginx基础环境搭建:

service iptables stop
iptables -I INPUT -p tcp --dport -j ACCEPT
vi /etc/sysconfig/selinux
selinux=disabled 创建文件夹
mkdir -p /usr/local/src
cd /usr/local/src 用户
useradd -s /sbin/nologin -M www
groupadd nginx 下载稳定版nginx1.10.3
yum -y install zlib* gcc gcc-c++ libtool openssl* automake autoconf libtool pcre*
wget http://nginx.org/download/nginx-1.10.3.tar.gz
cd nginx-1.10.
./configure --help ./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module --with-ld-opt='-ljemalloc'
--with-ld-opt这个优化的是nginx内存参数。 make && make install
ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin 创建家目录
mkdir -p /home/wwwlogs/
mkdir -p /usr/local/nginx/logs/
将编写好的nginx.conf 拷贝到nginx.conf
创建vhost,并属主属组,
chown -R www:www /home/wwwroot/
mkdir -p /home/wwwroot/ /usr/local/nginx/sbin/nginx
/usr/local/nginx/sbin/nginx -v
/usr/local/nginx/sbin/nginx -t netstat -antpu | grep nginx
curl ip地址 :查看能否正常运行nginx。
关于pid报错的信息,killall - nginx
编写自己启动文档。

[root@test1 html]# cat /usr/local/nginx/conf/nginx.conf

user  www www;
worker_processes auto;
#error_log /home/wwwlogs/nginx_error.log crit;

##If enable limit_conn_zone,add "limit_conn perip 10;" to server section. server_tokens off;
access_log off; include vhost/*.conf;
}

在nginx的配置文件中

location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000; 该处必须和php-fpm.conf中的lisen一样
#fastcigi_pass /tmp/php-cgi.sock
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

官网下载mysql(该配置文件没有优化mysql内存)

下载MySQL5..20源码包,和boost
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.20.tar.gz
wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz/ 添加用户和组MySQL,并且不允许登录
groupadd mysql
usradd -r -g mysql -s /sbin/nologin -M mysql
配置环境,解压包
yum -y install gcc gcc-c++ ncurses ncurses-devel bison libgcrypt perl make cmake
tar -xf mysql-5.7..tar.gz
cd mysql-5.7.
mkdir -p /usr/local/mysql/
mkdir -p /usr/local/boost/
cp boost_1_59_0.tar.gz /usr/local/boost 将包放到boost下
mkdir -p /data/mysql
其中data下的属主和属组必须是mysql,date是数据库目录。
ls /usr/local/mysql
chown -R mysql:mysql /data/mysql cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_UNIX_ADDR=/usr/local/mysql/mysql.sock -DSYSCONFDIR=/etc -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_MYISAM_STORAGE_ENGINE= -DWITH_INNOBASE_STORAGE_ENGINE= -DWITH_ARCHIVE_STORAGE_ENGINE= -DWITH_BLACKHOLE_STORAGE_ENGINE= -DENABLED_LOCAL_INFILE= -DMYSQL_DATADIR=/data/mysql -DDOWNLOAD_BOOST= -DMYSQL_TCP_PORT= -DENABLE_DOWNLOADS= -DWITH_BOOST=/usr/local/boost -DCMAKE_EXE_LINKER_FLAGS="-ljemalloc" -DWITH_SAFEMALLOC=OFF 此处做优化内容。
make && make install 将安装目录添加到环境变量中:
echo "export PATH=$PATH:/usr/local/mysql/bin">>/etc/profile
source /etc/profile
查看文件错误日志出现这行信息,
说明文件没有初始化,需要删除/data/mysql(数据库目录)下的文档
--18T15::.477533Z [ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
--18T15::.477899Z [ERROR] unknown variable 'default-file=/etc/my.cnf'
--18T15::.477915Z [ERROR] Aborting 初始化安装MySQL
cd /data/mysql 每次初始化时都要删除该目录下文件(数据库目录)
rm -rf ./*
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql \
--basedir=/usr/local/mysql --datadir=/data/mysql ps aux | grep mysql
会出现如下内容:
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ
mysql 27672 0.1 2.5 914052 49200 pts/1 Sl 00:11 0:00 /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/mysql-error.log --open-files-limit=65535 --pid-file=/usr/local/mysql/mysql.pid --socket=/usr/local/mysql/mysql.sock --port=3306
root 27721 0.0 0.0 103260 876 pts/1 S+ 00:15 0:00 grep 3306 6 配置my.cnf
在启动mysql服务时,会按照一定次序搜索my.cnf,先在/etc目录下找,找不到会搜索
$basedir/my.cnf 也就是安装目录,新版的配置文件默认位置。将/etc下的my.cnf备份
否则该文件会影响安装mysql的正确配置,造成无法启动。
cp my-default.cnf /etc/my.cnf
后台启动MySQL /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
正常启动后没有其他内容,回车一下就出来了。 查看MySQL是否启动
ps -aux | grep mysql
将启动的MySQL杀死
kill -9 进程号(两个)
只留下一个就好了:root 80654 0.0 0.0 103256 840 pts/1 S+ 08:18 0:00 grep mysql cd /usr/local/mysql/support-files
将其中的mysql-server复制到启动程序下,并改名为mysqld
cp mysql-server /etc/init.d/
mv mysql-server /etc/init.d/mysqld
chmod 755 mysqld 修改vi /etc/init.d/mysqld
basedir=/usr/local/mysql
datadir=/data/mysql 启动程序
/etc/init.d/mysqld restart 设置开机自启
chkconfig mysqld on
chkconfig --add mysqld 修改mysqld的密码
vi /etc/my.cnf
在mysqld下添加:skip-grant-tables
service mysqld restart
mysql -u root -p 此时密码为空
登录并修改mysql的root密码:
>use mysql;
>update user set authentication_string=password('123456') where user='root';
>flush privileges;
>quit
在5.7的版主中原来的password改为:authertication_string
在>select * from mysql.user \G; 中得到。
删除skip-grant-tables
重启服务

mysql -v

关于mysql配置过程中出错的问题

启动MySQL时出错:
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
[1] 32519
[root@slave1 mysql]# 2017-12-20T12:50:13.972444Z mysqld_safe error:
log-error set to '/usr/local/mysql/mysql-error.log',
however file don't exists. Create writable for user 'mysql'.
解决办法:
echo "" > /usr/local/mysql/mysql-error.log
chown -R mysql:mysql /usr/local/mysql/mysql-error.log
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &

关于pid的问题
当初始化时会产生一个pid,所以每次读取配置文件都要读取该pid
pid报错时候,用service mysqld restart不能读取,应该用
/usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf &
然后从错误的文档中查看。出现的报错信息时间会对不上,找最近的。

关于cmake时报错
CMake Error at cmake/boost.cmake:76 (MESSAGE):
Call Stack (most recent call first):
  cmake/boost.cmake:228 (COULD_NOT_FIND_BOOST)
 
  CMakeLists.txt:435 (INCLUDE)

-DWITH_BOOST=/usr/local/boost

解决方法二:
下载boost包,放到/usr/local/boost目录下,
cmake后面加选项 -DWITH_BOOST=/usr/local/boost

关于sock问题
2018-01-15T03:10:11.729108Z 0 [ERROR] Could not create unix socket lock file /usr/local/mysql/mysql.sock.lock.
