[root@localhost mysql]# tar -zxvf mysql-5.6.33-linux-glibc2.5-x86_64.tar.gz
[root@localhost mysql]# mv mysql-5.6.33-linux-glibc2.5-x86_64/ mysql
3.添加用户和用户组
#添加用户组

#添加用户mysql 到用户组mysql
[root@localhost mysql]# useradd -g mysql mysql
4.配置mysql
创建数据目录
[root@localhost mysql]# mkdir data
数据库数据默认目录datadir=/var/lib/mysql，可通过vim /etc/my.cnf 查看
设置权限：
[root@localhost mysql]# chown -R mysql:mysql data
[root@localhost mysql]# cd data
[root@localhost data]# pwd
/home/svr/application/mysql/data
执行安装脚本：
[root@localhost mysql]# ./scripts/mysql_install_db --user=mysql --datadir=/home/svr/application/mysql/data
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@localhost mysql]# chmod 755 /etc/init.d/mysqld
[root@localhost mysql]# cp support-files/my-default.cnf /etc/my.cnf
#修改启动脚本
[root@localhost mysql]# vi /etc/init.d/mysqld
#修改项(修改成自己服务上的目录)：
basedir=/home/svr/application/mysql/mysqldatadir=/home/svr/application/mysql/data#启动服务
[root@localhost mysql]# service mysqld start
相关命令：
#启动mysql
service mysqld start
#关闭mysql
service mysqld stop
#查看运行状态
service mysqld status
#加入环境变量，编辑 /etc/profile，这样可以在任何地方用mysql命令了
[root@localhost mysql]# vi /etc/profile
export PATH=$PATH:/home/svr/application/mysql/mysql#测试连接
[root@localhost mysql]# ./mysql/bin/mysql -uroot
