使用kill无法杀死mysql进程

问题背景：由于忘记了root密码，在没有关闭mysqld的进程时候，又执行了mysqld\_safe --skip-grant-tables --skip-networking & 命令

然后发现mysql开启了两个进程

ps -ef|grep mysql|grep -v mysql
    root       6528   5942  0 15:26 pts/3    00:00:00 /bin/sh /application/mysql/bin/mysqld_safe --skip-grant-tables
    mysql      6684   6528  1 15:26 pts/3    00:00:08 /application/mysql/bin/mysqld --basedir=/application/mysql --datadir=/application/mysql/data --plugin-dir=/application/mysql/lib/plugin --user=mysql --skip-grant-tables --log-error=db01.err --pid-file=db01.pid --socket=/tmp/mysql.sock --port=3306

[root@db01:~]# netstat -tunlp

    tcp6       0      0 :::3306                 :::*                    LISTEN      6684/mysqld
    tcp6       0      0 :::22                   :::*                    LISTEN      1491/sshd

使用kill、pkill、killall都无法杀死mysql进程，一直会重新启动一个新的进程，systemctl stop mysqld.service这个命令也不管用

后来使用/application/mysql/support-files/mysql.server stop停止成功
