centos 6.9安装mysql的实例教程

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, securityLoading mirror speeds from cached hostfile * base: mirrors.zju.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.aliyun.comInstalled PackagesMySQL-python.x86_64 1.2.3-0.3.c1.1.el6 @base                        mysql-libs.x86_64   5.1.73-8.el6_8     @anaconda-CentOS-201703281317.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

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 mysqlmysql:

4、查看系统中的mysql安装包

7、启动mysql服务

[root@cdh1 zjl]# service mysqld startInitializing MySQL database:  Installing MySQL system tables...OKFilling help tables...OKTo start mysqld at boot time you have to copysupport-files/mysql.server to the right place for your systemPLEASE 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_installationwhich will also give you the option of removing the testdatabases and anonymous user created by default.  This isstrongly 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.plcd /usr/mysql-test ; perl mysql-test-run.plPlease 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
