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 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. 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

3. ステップ 2 では yum を使用して mysql に関連するファイルを見つけます。アンインストールすると、mysql がクリーンアップされます。rpm を使用すると、クリーンアップされます。非常に面倒です。手動でクリアする必要があるファイルがたくさんあります
[root@cdh1 zjl]# whereis mysql mysql:
4. システム内の mysql インストール パッケージを確認します

7. mysql サービスを開始してから、接続を閉じます。 q.
[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_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!
