Jenkins用户在macOS更新后不见了

Question

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。

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->用户和组中没有jenkins用户。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：

chown: jenkins: illegal user name

我该如何解决？

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。我特别运行了此脚本：

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 minHeapSize 256m

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
