我试图让logstash作为root用户以外的用户所拥有的服务运行。 init.d脚本如下:
#!/bin/sh
### BEGIN INIT INFO

### END INIT INFO
# PATH should only include /usr/* if it runs after the mountnfs.sh script
PATH=/usr/sbin:/usr/bin:/sbin:/bin

TALEND_LOGSERV="/opt/talend/logserv"

当我将其作为服务运行时,我获得了成功的返回码,但是当我查找它时,logstash进程没有运行。 start_logserver脚本如下:
if [ "X${TALEND_LOGSERV}" = "X" ]; then
TALEND_LOGSERV="/opt/talend/logserv"
fi
cd "$TALEND_LOGSERV"
# ./logstash-1.4.2/bin/logstash agent -f logstash-talend.conf -l /var/log/talend/logserv.log > /dev/null 2>&1 < /dev/null &
echo "inside the start script...." >&2
echo `pwd` >&2
./logstash-1.4.2/bin/logstash agent -f logstash-talend.conf -l /var/log/talend/logserv.log
echo $!

可以为logstash
/ sysv
/ upstart
生成systemd
的服务脚本,其中包含:
LS_HOME=/usr/share/logstash
# use ONE of the following:
${LS_HOME}/bin/system-install ${LS_HOME}/config/startup.options sysv
${LS_HOME}/bin/system-install ${LS_HOME}/config/startup.options upstart
${LS_HOME}/bin/system-install ${LS_HOME}/config/startup.options systemd
这些脚本默认以logstash:logstash
运行。

@Magnus在评论中提供了一个非常有效的链接(elastic/logstash/pkg)。他最初的评论是:
您是否有任何理由没有使用init script that ships with Logstash作为起点?另外,您是否尝试使用-x运行这些shell脚本以列出所有运行的命令?作为最后的评论,start-stop-daemon捕获的pid不会是shell脚本而不是Logstash进程吗?
