二、Zabbix-zabbix server部署-LNMP

部署Zabbix server主要分为两部分（软件基本都是yum安装，不要问我为什么不用源码，因为没有必须用源码的需求）

一、部署LNMP/LAMP环境，已提供zabbix的界面展示，已经zabbix server的基础环境，这里不对LNMP/LAMP环境作过多解释。

这里使用LNMP作为Zabbix server的基础环境

系统：Centos7

Nginx：1.12.2

Php：7.0.27

Mysql：5.7.21

1.安装nginx

（1）添加yum源

cat <<EOF>/etc/yum.repo.d/nginx.repo
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=
enabled=
EOF

（2）yum安装nginx

yum -y install nginx
systemctl enable nginx　　#开机自启
systemctl start nginx　　 #启动

2.安装php（这里用的是5.7）

（1）添加php yum源

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

（2）yum安装php

yum -y install php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-mysql.x86_64 php70w-pdo.x86_64

yum -y install php70w-fpm    #安装php-fpm

（3）调整php参数，以满足zabbix安装要求

vim /etc/php.ini
更改以下参数的值
max_execution_time =
memory_limit = 128M
post_max_size = 16M
upload_max_filesize = 2M
max_input_time =
date.timezone = Asia/Shanghai

（4）调整php-fpm参数

vim /etc/php-fpm.d/www.conf
调整以下参数
user = nobody
group = nobody
listen = /dev/shm/php-fcgi.sock
listen.owner = nobody
listen.group = nobody
listen.mode = 

（5）启动php-fpm

systemctl enable php-fpm　 #开机自启
systemctl start php-fpm　　#启动

3.安装mysql

（1）安装mysql源

yum -y install https://www.percona.com/downloads/Percona-Server-LATEST/Percona-Server-5.7.21-20/binary/redhat/7/x86_64/Percona-Server-server-57-5.7.21-20.1.el7.x86_64.rpm

（2）启动mysql

systemctl enable mysqld　　#开机自启
systemctl start mysqld　　 #启动

（3）登录mysql

cat /var/log/mysqld.log |grep password    #获取mysql初始密码
[Note] A temporary password is generated for root@localhost: 9cd;rlPVSl;c

mysql -uroot -p'9cd;rlPVSl;c'

set password for 'root'@'localhost'=password('Dingkai.123');    #更改root密码

4.配置nginx连接php

乱七八糟的没用的干掉，改完以后大概这样子，有些功能，可以根据自己需求配置，这里仅供实现zabbix运行

cd /etc/nginx/conf.d
cp default.conf default.conf.bak　　#备份默认配置文件
vim default.conf
server {
    listen       ;
    server_name  localhost;
    root   /usr/share/nginx/html;

    #charset koi8-r;
    access_log  /var/log/nginx/host.access.log  main;

    location / {
        index  index.html index.htm index.php;
    }

    #error_page                /.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page        /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:
    #
    location ~ \.*php$ {
        fastcgi_pass  unix:/dev/shm/php-fcgi.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }
}

5.测试nginx，php，mysql连接性

cat<<EOF> /usr/share/nginx/html/mysql.php
<?php
$mysql = new mysqli();

$mysql->connect('localhost','root','root的登录密码');

if($mysql){

            echo "连接成功了!";
}else{

        echo "连接挂掉了";

}
phpinfo();
EOF

chow -R nobody.nobody /usr/share/nginx/html　　#因为php-fpm的运行用户是nobody,所以php相关的目录和代码的属主和属组，都用nobody

6.访问IP/mysql.php

至此，LNMP环境安装完成，接下来安装zabbix server
