Detailed tutorial on installing mysql on centos 6.9
|
1. Confirm whether MySQL has been installed. You can know it by the following code [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 1.2.3-0.3.c1.1.el6@base mysql-libs.x86_64 5.1.73-8.el6_8 @anaconda-CentOS-201703281317.x86_64/6.9 2. To uninstall the installed MySQL, it is recommended to use the yum command, because the yum command can automatically delete the dependencies related to MySQL; if you use the rpm command, you also need to manually delete the files related to MySQL, which is more troublesome.
[root@cdh1 zjl]# yum remove MySQL-python.x86_64 mysql-libs.x86_64
Loaded plugins: fastestmirror, refresh-packagekit, security

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
It 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!
