检查MySQL及相关RPM包，是否安装，如果有安装，则移除

[root@localhost ~]# rpm -qa | grep -i mysql
mysql-libs
[root@localhost ~]# yum -y remove mysql-libs*
[root@localhost ~]# rpm -ivh MySQL-server-5.6.30-1.el6.x86_64.rpm
[root@localhost ~]# rpm -ivh MySQL-client-5.6.29-1.el6.x86_64.rpm

注：MySql配置文件读取顺序，配置my.cnf

[root@localhost] find / -name my.cnf          #查找my.cnf所在位置 
[root@localhost] /usr/sbin/mysqld --verbose --help  | grep -A 1 "Default options" 
#Default options are read from the following files in the given order: 
#/etc/my.cnf /etc/mysql/my.cnf /opt/mysql/etc/my.cnf ~/.my.cnf

开机启动

[root@localhost ~]# chkconfig mysql on
[root@localhost ~]# chkconfig --list | grep mysql
mysql           0:off   1:off   2:on    3:on    4:on    5:on    6:off

MySQL的默认安装位置
/etc/init.d/mysql              #启动脚本，可以查看相关的默认路径
/var/lib/mysql/               #数据库目录
/usr/share/mysql              #配置文件目录
/usr/bin                     #相关命令目录 

启动MySQL&初始化密码

[root@localhost] /usr/bin/mysql_install_db 
[root@localhost] cat /root/.mysql_secret  #查看root账号密码

[root@localhost ~] mysql -uroot –paKWGvFV1qxvxtD5V
mysql> SET PASSWORD = PASSWORD('123456');    #设置密码为123456
mysql> exit
[root@localhost ~]# mysql -uroot -p123456

mysql> use mysql;
mysql> select host,user,password from user;
mysql> update user set password=password('123456') where user='root';
mysql> update user set host='%' where user='root' and host='localhost';
mysql> flush privileges;
mysql> exit
