MySQL is not running, but lock file (/var/lock/subsys/mysql[FAILED]

npm run dev 后需要重启 mysql，不知道为什么 mysql 的 pid 文件被删除了。
MySQL server PID file could not be found! [FAILED]

/var/lock/subsys/mysql 什么功能
/etc/init.d/mysqld 文件中指定了

Lock directory for RedHat / SuSE.

lockdir='/var/lock/subsys'
lock_file_path="$lockdir/mysql"

service mysqld start
mysqld_safe A mysqld process already exists

[ERROR] InnoDB: Cannot allocate memory for the buffer pool

The problem is that the server does not have enough memory to allocate for MySQL process. There are a few solutions to this problem.
(1) Increase the physical RAM. Adding 1GB of additional RAM will solve the problem.
(2) Allocate SWAP space. Digital Ocean VPS instance is not configured to use swap space by default. By allocating 512MB of swap space, we were able to solve this problem. To add swap space to your server, please follow the following steps:

杀死 php-fpm
kill -INT cat /usr/local/php7/var/run/php-fpm.pid
启动 php-fpm
/usr/local/php7/sbin/php-fpm
