⼆进制安装mysql mysql
# 1. 获取⼆进制代码包
wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz
# 2. 系统基础环境依赖安装
yum install ncurses-devel libaio-devel gcc make cmake -y
# 3.创建系统⽤户，之前创建过了，就⽆须执⾏了
[root@tech_master01 ~]# groupadd mysql
groupadd: group 'mysql' already exists
[root@tech_master01 ~]# useradd -g mysql mysql
useradd: user 'mysql' already exists
[root@tech_master01 ~]#
# 4.创建多实例的独⽴⽬录
[root@tech_master01 ~]# mkdir -p /my_mysql/{3306,3307}
# 5.解压缩mysql⼆进制压缩包
[root@tech_master01 ~]# tar -xzvf mysql-5.6.40-linux-glibc2.12-x86_64.tar.gz -C /application/
[root@tech_master01 ~]# yum -y install tree

[root@tech_master01 ~]# netstat -tunlp|grep mysql
# 2. 禁⽌开机⾃启
