8. 配置mysql服务开机自动启动
# cp /home/mysql/support-files/mysql.server /etc/init.d/mysqld
# 拷贝启动文件到/etc/init.d/下并重命令为mysqld
# chmod 755 /etc/init.d/mysqld # 增加执行权限
# chkconfig --list mysqld # 检查自启动项列表中没有mysqld这个，
# chkconfig --add mysqld # 如果没有就添加mysqld：
# chkconfig mysqld on # 用这个命令设置开机启动：
9. mysql服务启动/重启/停止
# service mysqld start # 启动服务
# service mysqld restart # 重启服务
# service mysqld stop # 停止服务

# cd /home/mysql
# ./bin/mysqladmin -u root -p ‘**mjT,#x_5sW‘ password ‘123456‘ mysqladmin: # 刚刚之前的初始密码
[Warning] Using a password on the command line interface can be insecure.
