NGINX_PID="/usr/local/nginx/logs/nginx.pid"
RETVAL=0
prog="Nginx"
start() 
{
    echo -n $"Starting $prog: "
    mkdir -p /dev/shm/nginx_temp
    daemon $NGINX_SBIN -c $NGINX_CONF
    RETVAL=$?
    echo
    return $RETVAL
}
stop() 
{
    echo -n $"Stopping $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -TERM
    rm -rf /dev/shm/nginx_temp
    RETVAL=$?
    echo
    return $RETVAL
}
reload()
{
    echo -n $"Reloading $prog: "
    killproc -p $NGINX_PID $NGINX_SBIN -HUP
    RETVAL=$?
    echo
    return $RETVAL
}
restart()
{
    stop
    start
}
configtest()
{
    $NGINX_SBIN -c $NGINX_CONF -t
    return 0
}
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  reload)
        reload
        ;;
  restart)
        restart
        ;;
  configtest)
        configtest
        ;;
  *)
        echo $"Usage: $0 {start|stop|reload|restart|configtest}"
        RETVAL=1
esac
exit $RETVAL

1.4 更改权限

代码语言：javascript复制

chmod 755 /etc/init.d/nginx

1.5 配置开机启动

代码语言：javascript复制

        {
            include fastcgi_params;
            fastcgi_pass unix:/tmp/php-fcgi.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;
        }    
    }
}

1.7 启动nginx服务

代码语言：javascript复制

/usr/local/nginx/sbin/nginx -t

/etc/init.d/nginx start

curl localhost  //本地测试 nginx

1.8 Nginx默认主机

编辑配置文件：

vim /usr/local/nginx/conf/nginx.conf

代码语言：javascript复制

events
{
    use epoll;
    worker_connections 6000;
}
http
{
    include mime.types;
    default_type application/octet-stream;
    server_names_hash_bucket_size 3526;
    server_names_hash_max_size 4096;
    log_format combined_realip '$remote_addr $http_x_forwarded_for [$time_local]'

    gzip_http_version 1.1;
    gzip_types text/plain application/x-javascript text/css text/htm
    application/xml;
    include vhost/*.conf;
}

1.9 创建虚拟server

代码语言：javascript复制

cd /usr/local/nginx/conf

mkdir vhost

cd vhost/

vim zhdy01.com.conf
//增加如下配置：

server
{
    listen 80 default_server;  
    server_name haha.com;
    index index.html index.htm index.php;
    root /data/wwwroot/www.zhdy01.com;
}

1.10 创建测试页面

代码语言：javascript复制

vim zhdy01.com.conf
完整目录为：牢记
(/usr/local/nginx/conf/vhost/zhdy01.com.conf
)

mkdir -p /data/wwwroot/www.zhdy01.com

cd /data/wwwroot/www.zhdy01.com

vim index.html

1.11 重载并测试

代码语言：javascript复制

/usr/local/nginx/sbin/nginx -t

/usr/local/nginx/sbin/nginx -s reload

1.12 添加PHP解析

在我们没有添加PHP文件解析前，访问一个PHP文件会直接全部输出：

在配置文件中（zhdy01.com.conf）添加如下：

代码语言：javascript复制

server
{
    listen 80 default_server;
    server_name www.zhdy01.com;
    index index.html index.htm index.php;
    root /data/wwwroot/www.zhdy01.com;

location ~ .php$
      {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/zhdy01.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/www.zhdy01.com$fastcgi_script_name;
      }

}

测试 重载 （-t && -s reload）

1.13 配置php-fpm

vim /usr/local/php-fpm/etc/php-fpm.conf 添加如下配置：

代码语言：javascript复制

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/zhdy01.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 15
pm.max_requests = 50
rlimit_files = 1024

1.14 设置本地hosts 我这是本地是，所以必须要添加hosts

1.15 上传wordpress文档到server，上传的具体位置就是咱们刚刚创建的：

代码语言：javascript复制

/data/wwwroot/www.zhdy01.com

[[email protected]03 www.zhdy01.com]# ls
index.php    readme.html      wp-admin            wp-comments-post.php  wp-config-sample.php  wp-cron.php  wp-links-opml.php  wp-login.php  wp-settings.php  wp-trackback.php
license.txt  wp-activate.php  wp-blog-header.php  wp-config.php         wp-content            wp-includes  wp-load.php        wp-mail.php   wp-signup.php    xmlrpc.php

注意：一定要把wordpress下的目录 文件上传到这儿

1.16 关闭firewalld或者添加80端口

代码语言：javascript复制

systemctl disable firewalld

systemctl stop firewalld

iptables -I INPUT -p tcp --dport 80 -j ACCEPT

1.17 进入下一步，出现如下信息。 进入我们的虚拟机，输入： （首次进入数据库）

代码语言：javascript复制

/usr/local/mysql/bin/mysql -uroot

设置mysql用户root的密码为：
SET password for 'root'@'localhost'=password('zhangduanya');

create database zhdy01； //创建一个数据库为zhdy01

grant all on zhdy01.* to 'zhdy01'@'127.0.0.1' identified by 'zhangduanya';
针对zhdy01这个数据库表授权，授权zhdy01用户且密码为zhangduanya

quit   //退出

再次测试：

/usr/local/mysql/bin/mysql -uzhdy01 -pzhangduanya -h127.0.0.1 //指定用户名haha 密码 主机再次测试登录。

1.18 验证wordpress

出错：

抱歉，我不能写入wp-config.php文件。

您可以手工创建wp-config.php文件并将以下信息贴入其中。

然后我们手动把下面的配置文件写入到wp-config.php中。

代码语言：javascript复制

vim wp-config.php

1.19 填写信息后，大功告成！

{
    listen 80;  
    server_name www.zhdy02.com;
    index index.html index.htm index.php;
    root /data/wwwroot/www.zhdy02.com;

##add php jiexi
location ~ .php$
      {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/zhdy02.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/www.zhdy02.com$fastcgi_script_name;
      }
}

2.2 配置php-fpm

代码语言：javascript复制

vim /usr/local/php-fpm/etc/php-fpm.conf

添加如下配置：

代码语言：javascript复制

[global]
pid = /usr/local/php-fpm/var/run/php-fpm.pid
error_log = /usr/local/php-fpm/var/log/php-fpm.log
[www]
listen = /tmp/php-fcgi.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 15
pm.max_requests = 50
rlimit_files = 1024

[zhdy02]
listen = /tmp/zhdy02.sock
listen.mode = 666
user = php-fpm
group = php-fpm
pm = dynamic
pm.max_children = 50
pm.start_servers = 10
pm.min_spare_servers = 5
pm.max_spare_servers = 15
pm.max_requests = 50
rlimit_files = 1024

注意：第一个是我们添加的zhdy01；
zhdy02才是我们配置的第二个。

测试&重载：

代码语言：javascript复制

/usr/local/php-fpm/sbin/php-fpm -t

/etc/init.d/php-fpm restart

ps aux | grep php-fpm

2.3 下载并移动站点文件 目录到vhost下的www.zhdy02.com：
