Centos7 安装LNMP环境

• 修改yum

   rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
  rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
  rpm -Uvh  http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
  

• 安装php、mysql、nginx

   yum -y install nginx
   yum -y install mysql-community-server
   yum -y install php70w-devel 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-pdo.x86_64   php70w-mysqlnd  php70w-fpm php70w-opcache php70w-pecl-redis php70w-pecl-mongo
  

• 配置mysql

  • MySQL 安装完成之后，在 /var/log/mysqld.log 文件中给 root 生成了一个默认密码

  • 通过下面的方式找到root 默认密码，然后登录 MySQL 进行修改

     systemctl start mysqld    # 启动 MySQL
     grep 'temporary password' /var/log/mysqld.log  # 查找默认密码
    2017-10-310T02:58:16.806931Z 1 [Note] A temporary password is generated for root@localhost: iacFXpWt-6gJ
    

  • 登录mysql

      ```
      mysql -uroot -p'iacFXpWt-6gJ'
      ```
    

  • 修改密码

    mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyPass1!';
    

    或者

    mysql> set password for 'root'@'localhost'=password('123abc');
    

  • 配置默认编码为 utf8：

     vim /etc/my.cnf
    [mysqld] ### 增加下面两行
    character_set_server=utf8
    init_connect='SET NAMES utf8'
    systemctl restart mysqld    # 重启 MySQL
    

  • 设置开机启动

    systemctl enable mysqld
    

  • 默认配置文件路径

    配置文件：/etc/my.cnf
    日志文件：/var/log/mysqld.log
    服务启动脚本：/usr/lib/systemd/system/mysqld.service
    socket 文件：/var/run/mysqld/mysqld.pid
    

• 配置nginx

systemctl status firewalld ### 防火墙 如果active (running) 则修改添加nginx规则
vi /etc/firewalld/zones/public.xml
<zone>
    ...
    <service name="nginx"/>
<zone>
systemctl reload firewalld  ### 重启防火墙

• 配置nginx。con

cp /etc/nginx/nginx.conf  /etc/nginx/nginx.conf_bak
