无法在 Ubuntu 中将 Jetty9 安装为服务
Unable to install Jetty9 as a service in Ubuntu
我已经按照 docs 安装 Jetty9 作为服务，但每当我 运行
service jetty start
如果没有消息，它会失败，我的 JETTY_HOME 是 /opt/jetty9，包含版本 9.4.14 的 home distribution。我还在 /usr/share/jetty9 使用我的网络应用程序和模块创建了我的 JETTY_BASE。
Jetty Home 和 Base 都属于用户 jetty。然后我将我的 init.d 文件夹符号链接为：
ln -s /opt/jetty9/bin/jetty.sh /etc/init.d/jetty
然后我创建了一个 /etc/default/jetty 文件，内容如下：
# change to 1 to prevent Jetty from starting
NO_START=0
# change to 'no' or uncomment to use the default setting in /etc/default/rcS
VERBOSE=yes
# Run Jetty as this user ID (default: jetty)
# Set this to an empty string to prevent Jetty from starting automatically
JETTY_USER=jetty
# The home directory of the Java Runtime Environment (JRE). You need at least
# Java 6. If JAVA_HOME is not set, some common directories for OpenJDK and
# the Oracle JDK are tried.
#JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
# Extra options to pass to the JVM
#JAVA_OPTIONS="-Xmx256m -Djava.awt.headless=true"
# Timeout in seconds for the shutdown of all webapps
#JETTY_SHUTDOWN=30
# Additional arguments to pass to Jetty
#JETTY_ARGS=
# Jetty uses a directory to store temporary files like unpacked webapps
TMPDIR=/opt/jetty9/tmp
JETTY_HOME=/opt/jetty9
JETTY_BASE=/usr/share/jetty9
# Default for number of days to keep old log files in /var/log/jetty9/
#LOGFILE_DAYS=14
# If you run Jetty on port numbers that are all higher than 1023, then you # do not need authbind. It is used for binding Jetty to lower port numbers.
# (yes/no, default: no)
#AUTHBIND=yes
JETTY_HOST=0.0.0.0
如果我在我的基础文件夹中使用 java -jar $JETTY_HOME/start.jar 启动 Jetty，它可以正常工作。另外，如果我 运行
service jetty supervise
它也 运行 没有问题，但是当我调用 start 时它失败了：
root@app:/usr/share/jetty9# service jetty start
Job for jetty.service failed because the control process exited with error code.
See "systemctl status jetty.service" and "journalctl -xe" for details.
root@app:/usr/share/jetty9# service jetty status

有什么想法吗？
更新
将 /etc/default/jetty 中的用户更改为 root 可以解决问题，但这不是解决方案，不是吗？
# Run Jetty as this user ID (default: jetty)
# Set this to an empty string to prevent Jetty from starting automatically
JETTY_USER=root
我终于成功了，jetty 用户应该有权访问以下文件夹，并且 /usr/sbin/nologin as shell 如 here 所述.
JETTY_HOME
JETTY_BASE
/var/run/jetty <-- couldn't find a reference to this folder in the docs
并将以下内容添加到您的/etc/default/jetty：
JETTY_SHELL=/bin/sh
JETTY_LOGS=/usr/share/jetty9/logs
JETTY_START_LOG=/usr/share/jetty9/logs/jetty-start-log.log
您还应该仔细检查您的文件夹中除了 jetty 之外没有其他用户拥有的剩余日志文件。
