CentOS 7 一键安装 MySQL

1. 使用 lnmp1.6 实现MySQL的自动化无人值守安装

[root@VM_0_5_centos ~]# cd /usr/local/src
[root@VM_0_5_centos src]# wget http://soft.vpser.net/lnmp/lnmp1.6.tar.gz -cO lnmp1.6.tar.gz && tar zxf lnmp1.6.tar.gz && cd lnmp1.6 && ./install.sh db

2.开放端口 及 配置 MySQL允许远程访问的IP地址

# 开放服务器端口
[root@VM_0_5_centos ~]# firewall-cmd --zone=public --add-port=3306/tcp --permanent
[root@VM_0_5_centos ~]# firewall-cmd --zone=public --add-port=3306/udp --permanent

# 配置MySQL远程登陆所允许的IP
[root@VM_0_5_centos ~]# mysql -uroot -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
