1. mysql がインストールされているかどうかは、次のコードから確認できます
[root@cdh1 zjl]# yum list installed mysql*Loaded plugins: fastestmirror, refresh-packagekit, security

2. インストールされた mysql をアンインストールするには、yum コマンドを使用することをお勧めします。 mysql; rpm コマンドを使用する場合は、mysql に関連するファイルを手動で削除する必要もありますが、これは非常に面倒です
[root@cdh1 zjl]# yum remove MySQL-python.x86_64 mysql-libs.x86_64

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_installationwhich 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 ]
