杀死mysqld进程问题
MySQL提供的启停脚本里面，用杀死mysqld进程停止mysql的'stop')
# Stop daemon. We use a signal here to avoid having to know the
# root password.
if test -s "$mysqld_pid_file_path"
then
# signal mysqld_safe that it needs to stop
touch "$mysqld_pid_file_path.shutdown"
mysqld_pid=`cat "$mysqld_pid_file_path"`
if (kill -0 $mysqld_pid 2>/dev/null)
then
echo $echo_n "Shutting down MySQL"
kill $mysqld_pid
# mysqld should remove the pid file when it exits, so wait for it.
wait_for_pid removed "$mysqld_pid" "$mysqld_pid_file_path"; return_value=$?
else
log_failure_msg "MySQL server process #$mysqld_pid is not running!"
rm "$mysqld_pid_file_path"
fi
为什么我自己kill mysqlpid 无法杀死msyqld进程，它会重新生成，杀不死呢？？？
按道理 mysqld 是响应 kill 命令的，你可以看看这个链接：
https://dev.mysql.com/doc/refman/5.7/en/unix-signal-response.html#client-signal-response
杀掉又重启的现象，你看看是不是有 mysqld_safe 进程在。 回复 2# seesea2517
我看了下它写的mysqld_safe脚本
它需要删除rm -f /var/lock/subsys/mysql这个文件才可以
我试了一下，是这样的~~~
