在Centos上安装MySQL时出现这样的错误：Starting MySQL.. ERROR! The server quit without updating PID file (/usr/loca

MySQL的版本是：mysql-5.5.48-linux2.6-x86_64.tar.gz

centos6.6上安装MySQL时出现的错误：

[root@hadoop mysql]# ./support-files/mysql.server start

Starting MySQL.. ERROR! The server quit without updating PID file (/usr/local/mysql/data/hadoop.pid).

解决办法：

进入到MySQL的安装目录，找到scripts文件夹，进入该文件夹执行如下的命令

[root@localhost scripts]# ./mysql_install_db --user=mysql --basedir=/usr/local/mysql  --datadir=/usr/local/mysql/data

然后再重新启动MySQL服务即可
