安装mysql

• centos6

• centos7
  MySQL的社区仓库：https://dev.mysql.com/downloads/repo/yum/

• 安装步骤：

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

安装nginx

• 安装步骤

  yum install epel-release
  yum -y install nginx
  

• Nginx 默认的HTML根目录是：/usr/share/nginx/html
  赋予权限
  chown -R nginx:nginx html/

  配置nginx

• 打开文件/etc/nginx/conf.d/default.conf
• 定义server容器

  [...]
    server {
        listen 80;
        listen [::]:80 default_server;
        server_name _;
        root /usr/share/nginx/html;
  
        # 设置默认主页
        index index.php index.html index.htm;
  
        location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            try_files $uri $uri/ =404;
        }
  
        # PHP脚本转发至PHP-FPM解析
        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_index index.php;
            include fastcgi_params;
        }
    }
  [...]
  

• 检查配置文件语法
  nginx -t

安装php-fpm

• 此版本过低
  yum install php php-mysql php-fpm
• 更换yum源

  　　#检查当前PHP的安装包
  　　yum list installed | grep php
  　　
  　　#移除当前PHP的安装包，否则容易起冲突
  　　yum remove php*
  　　
  　　#由于默认的YUM源无法升级PHP，所以需要添加第三方的YUM源，此处用到webtatic。
  　　#因为是CentOS 6.5，所以用以下URL
  　　rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
  　　#如果是CentOS 7.x
  　　rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm
  　　rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
  　　
  　　#查看YUM源上能用PHP安装包
  　　yum list php*
  　　
  　　#安装PHP5.5及需要的扩展
  　　yum install php55w php55w-devel php55w-common php55w-mysql php55w-pdo php55w-opacache php55w-xml
  　　
  　　#再次查看PHP版本，以确认安装是否成功
  

  配置php-fpm

• 打开文件 /etc/php-fpm.d/www.conf
• 修改内容,如下

  [...]
  listen = /var/run/php-fpm/php-fpm.sock
  [...]
  listen.owner = nobody
  listen.group = nobody
  [...]
  user = nginx
  group = nginx
  [...]
  

启动

service nginx start
service php-fpm start
service mysqld start
