紧急请教: mysql 无法正常启动 /usr/sbin/mysqld: Shutdown complete

  •

    这是一个创建于 88 天前的主题,其中的信息可能已经有所发展或是发生改变。

    原因:由于忘记及时续费一个站点,DO 设置成了 suspended 状态,续费后,DO power on 然而发现 mysql 状态是关闭的,然后我尝试启动失败。

    环境:openresty+php+mysql

    正常的:openresty 和 php-fpm 都是 active 状态

    非正常的:执行 systemctl status mysql

    ● mysqld.service - MySQL Community Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: failed (Result: start-limit) since Tue 2018-11-27 06:40:18 UTC; 9min ago Process: 2266 ExecStartPost=/usr/bin/mysql-systemd-start post (code=exited, status=0/SUCCESS) Process: 2265 ExecStart=/usr/bin/mysqld_safe --basedir=/usr (code=exited, status=203/EXEC) Process: 2250 ExecStartPre=/usr/bin/mysql-systemd-start pre (code=exited, status=0/SUCCESS) Main PID: 2265 (code=exited, status=203/EXEC)
