CentOS 7 初始化mysql

To initialize MySQL on CentOS 7, you can follow these steps:

1. Install MySQL by running the following command:

   sudo yum install mysql-server
   

2. Start the MySQL service by running the following command:

   sudo systemctl start mysqld
   

3. Run the MySQL secure installation script to set a root password and secure the installation:

   sudo mysql_secure_installation
   

   This script will guide you through setting a root password, removing anonymous users, disallowing remote root login, and removing test databases.

4. Enable the MySQL service to start on boot by running the following command:

   sudo systemctl enable mysqld
   

5. Verify that the MySQL service is running by running the following command:

   sudo systemctl status mysqld
   

   If the service is running, you should see an output indicating that it is active (running).

That's it! You have successfully initialized MySQL on CentOS 7
