二、搭建 LNMP 环境

1. 查看 wget 是否安装

   
   `rpm -qa wget`
   
   没有则安装
   
   `yum install wget`
   

2. 查看是否安装编译器

   
   `rpm -qa gcc`
   
   没有则安装
   
   `yum install gcc gcc-c++`
   

3. 安装 Nginx

• 安装 Nginx 依赖：

yum -y install pcre pcre-devel
     yum -y install zlib zlib-devel
     yum -y install openssl openssl-devel

• 下载并解压 Nginx：

cd /usr/local/src
     wget http://nginx.org/download/nginx-1.18.0.tar.gz
     tar -zxvf nginx-1.18.0.tar.gz

• 编译安装 Nginx：

cd nginx-1.18.0
     ./configure --prefix=/usr/local/nginx
     make
     make install

• 创建 nginx 账号：

groupadd nginx
     useradd -M -g nginx -s /sbin/nologin nginx
     cd /usr/local/nginx/conf

vim nginx.conf
将第一行 user 改为：
user nginx nginx
完成后执行命令
/usr/local/nginx/sbin/nginx -t
ESC+:wq+Enter 退出并保存

1. 启动 Nginx：/usr/local/nginx/sbin/nginx ，浏览器输入服务器公网 IP，出现 Welcome to nginx! 则启动成功

2. 安装 MySQL

• 下载并应用 MySQL 的 yum 资源包：

cd ~
     wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
     rpm -ivh mysql-community-release-el7-5.noarch.rpm
     yum update
     yum install mysql-server

• 改变文件属主和属组：

  
  `chown mysql:mysql -R /var/lib/mysql`
  

• 初始化并启动 MySQL：

  
  `mysqld --initialize`
  
  `service mysqld start`
  

• 修改密码并登陆 MySQL：

  
  `mysqladmin -u root password "your-password"`
  
  `mysql -u root -p`
  
  输入密码登陆，出现`mysql>`则成功
  
  

1. 安装 PHP

• 安装 PHP 依赖：

yum install 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

• 下载 PHP：

  
  `wget https://www.php.net/distributions/php-7.3.21.tar.gz`
  
  `tar -zxvf php-7.3.21.tar.gz`
  

• 编译安装：

cd php-7.3.21
     ./configure --prefix=/usr/local/php --disable-fileinfo --enable-fpm --with-config-file-path=/etc --with-config-file-scan-dir=/etc/php.d --with-openssl --with-zlib --with-curl --enable-ftp --with-gd --with-xmlrpc --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-gd-native-ttf --enable-mbstring --with-mcrypt=/usr/local/libmcrypt --enable-zip --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-mysql-sock=/var/lib/mysql/mysql.sock --without-pear --enable-bcmath
     make
     make install

• 移动 PHP 配置文件：

  
  `cp php.ini-development /etc/php.ini`
  

• 配置 php-fpm 运行账号：

cd /usr/local/php/etc
     cp php-fpm.conf.default php-fpm.conf
     cd php-fpm.d
     cp www.conf.default www.conf

vim www.conf
将其中的user=nobody和group=nobody改为user=nginx和group=nginx

1. 使 Nginx 支持 PHP

• 修改配置文件：vim /usr/local/nginx/conf/nginx.conf

#location ~ .php$ {
         #    root           html;
         #    fastcgi\_pass   127.0.0.1:9000;
         #    fastcgi\_index  index.php;
         #    fastcgi\_param  SCRIPT\_FILENAME  /scripts$fastcgi\_script\_name;
         #    include        fastcgi\_params;
         #}

将其中的改为注释取消，ESC+:wq+Enter 退出并保存

• 将 Nginx 添加到系统服务：

  
  `vim /etc/init.d/nginx`
  
  ​ 内容为：
  
  

#!/bin/sh
     # nginx - this script starts and stops the nginx daemin
     #
     # chkconfig:   - 85 15
     # description:  Nginx is an HTTP(S) server, HTTP(S) reverse

          lockfile=/var/lock/subsys/nginx
          start() {
              \[ -x $nginx \] || exit 5
              \[ -f $NGINX\_CONF\_FILE \] || exit 6
              echo -n $"Starting $prog: "

              retval=$?
              echo
              \[ $retval -eq 0 \] && touch $lockfile
              return $retval
          }
             stop() {
              echo -n $"Stopping $prog: "
              killproc $prog -QUIT
              retval=$?
              echo
              \[ $retval -eq 0 \] && rm -f $lockfile
              return $retval
          }
                      restart() {
              configtest || return $?
              stop
              start
          }
               reload() {
              configtest || return $?
              echo -n $"Reloading $prog: "
              killproc $nginx -HUP
              RETVAL=$?
              echo
          }
          force\_reload() {
              restart
          }
               configtest() {
            $nginx -t -c $NGINX\_CONF\_FILE
          }
                    rh\_stlatus() {
              status $prog
          }
               rh\_status\_q() {
              rh\_status >/dev/null 2>&1
          }
          case "$1" in
              start)
                  rh\_status\_q && exit 0

             exit 2
          esac

chmod 755 /etc/init.d/nginx
chkconfig –add nginx

• 重启 Nginx：

  
  `service nginx restart`
  
  

1. 设置 php-fpm 为系统服务：

• 添加配置文件：

  
  `vim /etc/systemd/system/php-fpm.service`
  
  内容为
  
  

\[Unit\]
          Description=php-fpm
          After=network.target
          \[Service\]
          Type=forking
          ExecStart=/usr/local/php/sbin/php-fpm
          PrivateTmp=True
          \[Install\]
          WantedBy=multi-user.target

ESC+:wq+Enter 退出并保存

1. 设置 php-fpm 开机自启并启动 php-fpm：

• 设置 php-fpm 开机自启动：

  
  `systemctl enable php-fpm.service`
  

• 启动 php-fpm：

  
  `systemctl start php-fpm.service`
  

• 查看启动是否成功：

  
  `ps aux | grep php-fpm`
  
  

三、搭建微擎

1. 创建站点：

• 创建 Nginx 配置文件

  
  `mkdir -p /usr/local/nginx/vhost/weengine`
  
  `vim /usr/local/nginx/vhost/vhost_weengine.conf`
  
  内容为：
  
  

server {
             listen       80;
             server\_name  localhost;
                  #charset koi8-r;
                  #access\_log  logs/host.access.log  main;
                  location / {
                 root   vhost/weengine;
                 index  index.html index.htm;
             }
                  #error\_page  404              /404.html;
                  # redirect server error pages to the static page /50x.html
             #
             error\_page   500 502 503 504  /50x.html;
             location = /50x.html {
                 root   html;
             }
                  # proxy the PHP scripts to Apache listening on 127.0.0.1:80
             #
             #location ~ .php$ {
             #    proxy\_pass   http://127.0.0.1;
             #}
                  # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
             #
             location ~ .php$ {
                 root           html;
                 fastcgi\_pass   127.0.0.1:9000;
                 fastcgi\_index  index.php;
                 fastcgi\_param  SCRIPT\_FILENAME /usr/local/nginx/vhost/weengine$fastcgi\_script\_name;
                 include        fastcgi\_params;
             }
                  # deny access to .htaccess files, if Apache's document root
             # concurs with nginx's one
             #
             #location ~ /.ht {
             #    deny  all;
             #}
         }
          vim /usr/local/nginx/conf/nginx.conf
           修改nginx默认端口listen       800;
          include /usr/local/nginx/vhost/\*.conf;

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

在 http{} 代码块最后添加

include /usr/local/nginx/vhost/*.conf;

重启 nginx

service nginx restart

• 下载并解压微擎

  
  `cd /usr/local/nginx/vhost/weengine`
  
  `wget https://cdn.w7.cc/download/WeEngine-Laster-Online.zip`
  
  `unzip https://cdn.w7.cc/download/WeEngine-Laster-Online.zip`
  
  

1. 配置微擎

• 浏览器输入公网 IP/install.php 按提示一步步配置即可
