1、确认mysql是否已安装,有下面的代码可知

[root@cdh1 zjl]# yum list installed mysql*
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: mirrors.zju.edu.cn
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
Installed Packages
MySQL-python.x86_64 1.2.-0.3.c1..el6 @base
mysql-libs.x86_64 5.1.-.el6_8 @anaconda-CentOS-.x86_64/6.9

2、卸载已安装的mysql,建议使用yum命令,因为yum命令可以自动删除与mysql相关的依赖;如果使用rpm命令,则还需要手动去删除和mysql相关的文件,比较麻烦

[root@cdh1 zjl]# yum remove MySQL-python.x86_64 mysql-libs.x86_64
Loaded plugins: fastestmirror, refresh-packagekit, security

3、用whereis命令查找mysql相关的文件,因为步骤2用yum来卸载,所以mysql被清理得很干净;如果使用rpm将会很麻烦,有很多的文件需要手动清除

[root@cdh1 zjl]# whereis mysql
mysql:

4、查看系统中的mysql安装包

[root@cdh1 zjl]# yum list mysql*

7、启动mysql服务

[root@cdh1 zjl]# service mysqld start
Initializing MySQL database: Installing MySQL system tables...
OK
Filling help tables...
OK To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands: /usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h cdh1.zjl.com password 'new-password' Alternatively you can run:
/usr/bin/mysql_secure_installation which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers. See the manual for more instructions. You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe & You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/bin/mysqlbug script! [ OK ]
Starting mysqld: [ OK ]

8、连接一下试一下,直接mysql然后\q关闭连接

[root@cdh1 zjl]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is
Server version: 5.1. Source distribution Copyright (c) , , Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> \q
Bye

9、设置mysql开机启动

[root@cdh1 zjl]# chkconfig mysqld on

10、开启3306端口,并保存

[root@cdh1 zjl]# /sbin/iptables -I INPUT -p tcp --dport  -j ACCEPT
[root@cdh1 zjl]# /etc/rc.d/init.d/iptables save

11、连接mysql设置密码

[root@cdh1 zjl]# mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is

mysql> update user set password=password('') where user='root';
Query OK, rows affected (0.02 sec)
Rows matched: Changed: Warnings: mysql> flush privileges;
Query OK, rows affected (0.02 sec) mysql> \q
Bye

12、重启mysql服务

[root@cdh1 zjl]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
