Jenkins用户在macOS更新后不见了 [英] Jenkins user is gone after macOS update

问题描述

我在Mac上将Jenkins作为CI服务器运行.在具有用户jenkins的典型设置的情况下，它在macOS 10.12上运行良好.

I'm running Jenkins as a CI server on a Mac. It was running fine on macOS 10.12 with the typical setup with user jenkins.

今天，我将macOS升级到10.13(High Sierra).升级过程完成后，Jenkins无法启动.此外，系统上没有用户詹金斯.所有Jenkins文件都存在，但是在设置"->用户和用户"中没有jenkins用户.团体.如果我尝试在终端中使用jenkins用户，例如，如果我尝试使用chown将文件所有权更改为jenkins，则会得到:

Today I upgraded macOS to 10.13 (High Sierra). Jenkins could not start after the upgrade process completed. Furthermore, there was no user jenkins on the system. All Jenkins files are there, but there is no jenkins user in Settings -> Users & Groups. If I try to use jenkins user in Terminal, for instance if I try to change file ownership to jenkins with chown, I get:

chown: jenkins: illegal user name

我该如何解决?

推荐答案

通过从Jenkins安装中提取创建用户的脚本命令，我设法重新创建了该用户.我特别运行了该脚本:

I've managed to re-create jenkins user by extracting the script commands that create it from Jenkins installation. I ran this script in particular:

JENKINS_HOMEDIR="/Users/Shared/Jenkins"
DEFAULTS_PLIST="/Library/Preferences/org.jenkins-ci.plist"

if dscl . -list /Users/jenkins; then
    echo 'jenkins user already exists, attempting to change the shell to /bin/bash'
    # Will fail if UserShell is not /usr/bin/false, but that's ok.
    # Then we will assume an admin has changed it.
    dscl . -change /Users/jenkins UserShell /usr/bin/false /bin/bash
else
    echo 'No jenkins user found, creating jenkins user and group'

# Find free uid under 500
    uid=$(dscl . -list /Users uid | sort -nrk 2 | awk '$2 < 500 {print $2 + 1; exit 0}')
    if [ $uid -eq 500 ]; then
        echo 'ERROR: All system uids are in use!'
        exit 1
    fi
    echo "Using uid $uid for jenkins"

    gid=$uid
    while dscl -search /Groups gid $gid | grep -q $gid; do
        echo "gid $gid is not free, trying next"
        gid=$(($gid + 1))
    done
    echo "Using gid $gid for jenkins"

    dscl . -create /Groups/jenkins PrimaryGroupID $gid

    dscl . -create /Users/jenkins UserShell /bin/bash
    dscl . -create /Users/jenkins Password '*'
    dscl . -create /Users/jenkins UniqueID $uid
    dscl . -create /Users/jenkins PrimaryGroupID $gid
    dscl . -create /Users/jenkins NFSHomeDirectory "$JENKINS_HOMEDIR"

    dscl . -append /Groups/jenkins GroupMembership jenkins
fi

# identify the real default group name for user jenkins
groupid=`dscl . read /Users/jenkins PrimaryGroupID | awk '{print $2}'`
gname=`id -n -g $groupid`

echo "Using jenkins:${gname} as file owner and group for jenkins daemon files"

find "$JENKINS_HOMEDIR" \( -not -user jenkins -or -not -group ${gname} \) -print0 | xargs -0 chown jenkins:${gname}

# Add defaults for heap sizing
arch=$(uname -m)
if [ $arch = 'x86_64' ]; then
    defaults write $DEFAULTS_PLIST heapSize 512m
    defaults write $DEFAULTS_PLIST permGen 512m
    defaults write $DEFAULTS_PLIST minHeapSize 256m
    defaults write $DEFAULTS_PLIST minPermGen 256m
else
    # i386
    defaults write $DEFAULTS_PLIST heapSize 128m
    defaults write $DEFAULTS_PLIST permGen 128m
    defaults write $DEFAULTS_PLIST minHeapSize 64m
    defaults write $DEFAULTS_PLIST minPermGen 64m    
fi

defaults write $DEFAULTS_PLIST httpPort 8080

# Set tmpdir
JENKINS_TMPDIR="$JENKINS_HOMEDIR/tmp"
defaults write $DEFAULTS_PLIST tmpdir $JENKINS_TMPDIR
mkdir -p $JENKINS_TMPDIR
chown jenkins:${gname} $JENKINS_TMPDIR

# Create log directory, which can be written by Jenkins daemon
mkdir -p /var/log/jenkins
chown jenkins:${gname} /var/log/jenkins
