3. Configure MySQL:

Create MySQL groups and accounts

[sql]  view plain  copy

 

1. <span style="font-family:'Microsoft YaHei';font-size:16px;">groupadd mysql  
2. useradd -g mysql mysql</span>  

edit permission:

[sql]  view plain  copy

 

1. <span style="font-family:'Microsoft YaHei';font-size:16px;">chown -R mysql:mysql /usr/local/mysql</span>  

Initialize the configuration, enter the installation path (execute the following instructions), execute the initialization configuration script, and create the database and tables that come with the system

[sql]  view plain  copy

 

1. <span style="font-family:'Microsoft YaHei';font-size:16px;">cd /usr/local/mysql  
2. scripts/mysql_install_db --basedir=/www.leyou1178.cn usr/local/mysql--datadir=/usr/local/mysql/data --user=mysql</span>  

We will use the configuration file /usr/local/mysql/my.cnf in the future. In order to prevent interference, we will rename my.cnf under etc.

[sql]  view plain  copy

 

1. <span style="font-family:'Microsoft YaHei';font-size:16px;">mv /etc/my.cnf /etc/my.cnf.bak</span>  

4. Start MySQL

Add a service, copy the service script to the init.d directory, and set it to start on boot

[sql]  view plain  copy

 

1. <span style= "font-family:'Microsoft YaHei';font-size:16px;"> Execute under /usr/local/mysql  
2. cp support-files/mysql.server /etc/init.d/mysql  
3. chkconfig mysql on  
4. service mysql start --start  MySQL</span>  

start mysql client

[sql]  view plain  copy

 

1. <span style="font-family:'Microsoft YaHei';font-size:16px;">cd /usr/local/mysql/bin  
2. ./mysql -uroot -p www.baohuayule.cn </span>  

The entire MySQL configuration is completed, I wish you a happy use~
