一、安装Apache
1、安装httpd服务：
sudo yum install httpd
2、开启服务：
sudo systemctl start httpd
3、访问服务器IP成功显示Testing 123.. ，即安装成功
4、其他命令
重启服务：sudo systemctl restart httpd 停止服务：sudo systemctl stop httpd 查看软件安装位置：rpm -ql httpd 查看版本：sudo httpd -v 配置文件目录：etc/httpd/conf/httpd.conf 项目地址：var/www/html 默认显示页面地址（Test）： usr/share/httpd/noindex
二、安装MySQL
1、获取repo源
wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
2、安装rpm包
rpm -ivh mysql-community-release-el7-5.noarch.rpm
3、安装MySQL
yum install mysql-community-server
4、开机启动MySQL配置
执行命令：vi /etc/rc.local，新增一行service mysqld start，保存退出即可（先按Esc键，在按英文: ，输入wq即可保存退出）
#!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES # # It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. # # In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. # # Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. touch /var/lock/subsys/local systemctl start mysqld ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ "/etc/rc.local" 14L, 496C
5、启动mysql
启动：systemctl start mysqld
重启：systemctl restart mysqld
停止：systemctl stop mysqld
需要先启动mysql，不然操作mysql时会报错：Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'
6、设置密码及远程登录设置
登录MySQL：mysql -u root 重置密码：set password for 'root'@'localhost' =password('1234'); 设置远程登录：grant all privileges on *.* to root@'%'identified by '1234'; 分配权限：create user 'username'@'%' identified by '1234';
