以上是logstash服务启动时的命令输出。（通过将-x开关添加到init.d脚本的开头 - ＃！/ bin / sh -x ）来实现此目的

使用Ubuntu 14.04上的DEB软件包安装Logstash v2.2.0

当我运行init脚本使用的exec命令时（如上面的输出所示），logstash启动程序非常好并且运行完美

"/opt/logstash/bin/logstash" agent -f /etc/logstash/conf.d -l /var/log/logstash/logstash.log

init.d服务脚本中存在导致logstash作为服务失败的内容。我怀疑init脚本使用的 nice 命令。

你们看到＆＃39; nice ＆＃39;在init脚本中使用的命令？

    + nice -n 19 chroot --userspec logstash:logstash --groups logstash / sh -c 
    cd /var/lib/logstash
    ulimit -n 16384
    exec "/opt/logstash/bin/logstash" agent -f /etc/logstash/conf.d -l /var/log/logstash/logstash.log

当您卸载旧版本时，logstash用户和组也被删除了。现在，在新安装的情况下，使用不同的logstash和uid创建了一个新的gid用户和组。但是，常见logstash目录的所有权属于旧logstash uid和gid。现在，当您启动新的logstash时，它会尝试读取/写入此目录并因此失败，因此logstash未运行。尝试更改这些目录的所有权并启动logstash

chown -R logstash:logstash /var/log/logstash
chown -R logstash:logstash /var/lib/logstash
chown -R logstash:logstash /etc/logstash
rm -rf /var/run/logstash.pid
/etc/init.d/logstash start

Logstash v2.2.0无法作为服务启动
