mysql-The-server-quit-without-updating-PID-file

mysql 编译后执行 /etc/init.d/mysqld start 启动失败 提示："The server quit without updating PID file"

排查思路： 寻找配置文件 --》寻找错误日志 --》 根据日志排查错误

 grep -i log /etc/my.cnf 
log-error=/var/log/mariadb/mariadb.log
log-error=/var/log/mysqld.log

找到日志目录：/var/log/mariadb/mariadb.log
