在初始化脚本中切换用户？

发布于 2024-12-27 22:37:37 字数 286 浏览 3 评论 0原文

这是我的 Ubuntu 工作站上的初始化脚本。我需要以除 root 之外的其他用户身份运行命令，但我就是不知道应该如何完成它。 sudo -u 或 su newuser 似乎都不起作用。

脚本：

respawn
console none

start on runlevel [2345]
stop on runlevel [06]

script
  su "anotherUser" -c ./myCommand
end script

Here's my Init script which I have at my Ubuntu workstation. I need to run a command as another user than root, but I just can't get my head around how it should be done. Neither sudo -u or su newuser seems to work.

The script:

respawn
console none

start on runlevel [2345]
stop on runlevel [06]

script
  su "anotherUser" -c ./myCommand
end script

我使用这个：

su -l $MUSER -c "myCommand args..."

更新：由于有人对此答案感兴趣，我在这里解释一下我使用它的方式。

我们以普通 Linux 用户身份运行服务器，而不是 root。用户名包含三部分：

service、customer、stage

这样我们就可以在一个 Linux 操作系统中为多个客户运行多个服务。

示例： foo_bar_p 客户“bar”的服务“foo”，“p”表示生产

以下是初始化脚本的部分。初始化脚本可以作为 root 或 foo_bar_p 用户执行：

# /etc/init.d/foo_bar_p-celeryd
# scriptname contains linux username  
SCRIPT_NAME=`basename "$0"`
SYSTEM=${SCRIPT_NAME%*-celeryd}

U=`id -nu`

if [ ! $U == $SYSTEM ]; then
    if [ $U == "root" ]; then
        # use "-l (login)" to delete the environment variables of the calling shell.
        exec su -l $SYSTEM -c "$0 $@"
    fi
    echo "Script must be run from $SYSTEM or root. You are '$U'"
    rc_exit 1
fi

# OK, now I am foo_bar_p
cd
. $HOME/.bashrc
....

I use this:

su -l $MUSER -c "myCommand args..."

Update: Since there is interest in this answer, I explain the way I use it here.

We run servers as normal linux users, not root. The username contains three parts:

service, customer, stage

This way we can run several services for several customers in one linux OS.

Example: foo_bar_p Service "foo" of customer "bar" and "p" means production

Here is the part of the init script. The init script can be executed as root or as foo_bar_p user:

# /etc/init.d/foo_bar_p-celeryd
# scriptname contains linux username  
SCRIPT_NAME=`basename "$0"`
SYSTEM=${SCRIPT_NAME%*-celeryd}

U=`id -nu`

if [ ! $U == $SYSTEM ]; then
    if [ $U == "root" ]; then
        # use "-l (login)" to delete the environment variables of the calling shell.
        exec su -l $SYSTEM -c "$0 $@"
    fi
    echo "Script must be run from $SYSTEM or root. You are '$U'"
    rc_exit 1
fi

# OK, now I am foo_bar_p
cd
. $HOME/.bashrc
....
