【问题描述】：

短版：我用mysql_safe启动mysql，杀不了。

长版：使用 macport 安装旧版本的 mysql 显示此建议：

$ sudo port install mysql55-server
--->  Computing dependencies for mysql55-server
--->  Fetching archive for mysql55-server
--->  Attempting to fetch mysql55-server-5.5.49_0.darwin_14.noarch.tbz2 from https://packages.macports.org/mysql55-server
--->  Attempting to fetch mysql55-server-5.5.49_0.darwin_14.noarch.tbz2.rmd160 from https://packages.macports.org/mysql55-server
--->  Installing mysql55-server @5.5.49_0
--->  Activating mysql55-server @5.5.49_0

If this is a new install you might want to run:

$ sudo -u _mysql /opt/local/lib/mysql55/bin/mysql_install_db

给出这些指令的运行：

$ sudo -u _mysql /opt/local/lib/mysql55/bin/mysql_install_db
Installing MySQL system tables...
161102 13:15:44 [Note] /opt/local/lib/mysql55/bin/mysqld (mysqld 5.5.49) starting as process 54176 ...
OK
Filling help tables...
161102 13:15:44 [Note] /opt/local/lib/mysql55/bin/mysqld (mysqld 5.5.49) starting as process 54180 ...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/opt/local/lib/mysql55/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql55/bin/mysqladmin -u root -h myusername password 'new-password'

Alternatively you can run:
/opt/local/lib/mysql55/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /opt/local ; /opt/local/lib/mysql55/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /opt/local/mysql-test ; perl mysql-test-run.pl

Please report any problems at http://bugs.mysql.com/

此时我（似乎是不明智地）跑了：

$ cd /opt/local ; /opt/local/lib/mysql55/bin/mysqld_safe &

现在我不知道如何停止 mysql 和/或守护进程：

$ ps aux | grep mysql55
myusername        54937   0.1  0.0  2432772    660 s001  R+    1:39PM   0:00.00 grep mysql55
_mysql         54888   0.0  0.1  2667884   6340   ??  S     1:36PM   0:00.12 /opt/local/lib/mysql55/bin/mysqld --user=_mysql
root           54885   0.0  0.0  2479468    700   ??  Ss    1:36PM   0:00.00 /opt/local/bin/daemondo --label=mysql55-server --start-cmd /opt/local/lib/mysql55/bin/mysqld --user=_mysql ; --pid=exec

我尝试了许多 kill 变体，针对 mysql（这似乎毫无意义）和 daemondo，包括（但不限于）以下内容：

sudo kill -9 54888 // killing the mysql process results in a new pid sudo kill 54885 // the doemondo process sudo kill -SIGHUP 54885 sudo killall mysqld_safe sudo kill -9 54822 // a reincarnation of the doemondo process sudo mysqladmin shutdown

【问题讨论】：

这里有好主意：***.com/questions/11091414/how-to-stop-mysqld?

@Schipe 是的，我的许多失败尝试都来自该帖子。其中许多建议都是针对包管理器（brew 或 macport）的，因为我直接运行了mysql_safe，所以没有帮助。其他解决方案针对 mysql，这对我没有帮助，因为一旦被杀死，mysql 进程就会重新创建。谢谢，但我正在寻找特定于 mysql_safe 的答案。

mysqladmin shutdown 当然应该有效。 mysqld_safe 应该允许 MySQL 在自愿停止时终止，而不是崩溃或被杀死，但您当然必须指定 -u 和 -p 和 mysqladmin。

这个对我有用：***.com/questions/37879448/…

@Michael-sqlbot，如果这是初始设置并且您遇到密码问题，则不会。你可以得到auth_socket 问题。

【参考方案1】：

对于 centos 或 mint

 /usr/bin# initctl 

对于 ubuntu

 pkill mysqld
