启动和用户映射
我试图让 MySQL 在 launchd 下运行，因此我设置了一个 launchd 项，其中包含一个“UserName”键，其中“mysql”作为值。我这样做是因为当我启动 mysql 时，我通常会执行：mysqld_safe --user=mysql。
当我加载它时，我得到：
10/22/10 11:13:02 AM com.apple.launchd[1] (com.mysql.mysqld463) Suspicious setup: User "mysql" maps to user: _mysql
10/22/10 11:13:02 AM com.apple.launchd[1] (com.mysql.mysqld) Throttling respawn: Will start in 10 seconds
MySQL 永远不会运行。我应该使用“_mysql”作为用户吗？我想知道用户映射，因为我按照 MySQL 发行版中包含的说明安装了数据库：使用 mysql 用户安装数据库并运行守护程序。
先感谢您。
I'm trying to get MySQL to run under launchd so I set up a launchd item including a "UserName" key with "mysql" as value. I did this because when I start mysql I usually go: mysqld_safe --user=mysql.
When I load it, I get:
10/22/10 11:13:02 AM com.apple.launchd[1] (com.mysql.mysqld463) Suspicious setup: User "mysql" maps to user: _mysql
10/22/10 11:13:02 AM com.apple.launchd[1] (com.mysql.mysqld) Throttling respawn: Will start in 10 seconds
And MySQL never gets to run. Should I use "_mysql" as the user? I wonder about user mappings because I installed my databases following instructions included in MySQL distribution: using the mysql user to install databases and to run the daemon.
Thank you in advance.

只需让
launchd运行您通常运行的命令即可。一个更改是使用mysqld_safe的绝对路径。然后，mysqld_safe将生成一个以mysql用户身份运行的mysql进程，然后您将回到熟悉的区域。Just have
launchdrun exactly the command you would normally run. The one change would be to use an absolute path tomysqld_safe.mysqld_safewill then spawn amysqlprocess running as the usermysql, and you'll be back in familiar territory.
