当有两个 IP 地址时，mongodb 服务无法启动

当有两个 IP 地址时，mongodb 服务无法启动

在 /etc/mongodb.conf 文件中我有这个设置 bindIp：“127.0.0.1,192.168.1.51”，192.168.1.51 是我的路由器提供的私有 IP。当我执行 systemctl status mongodb 时：

mongodb.service - High-performance, schema-free document-oriented database
   Loaded: loaded (/usr/lib/systemd/system/mongodb.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Mon 2016-09-26 17:51:40 CST; 32s ago
   Process: 1070 ExecStart=/usr/bin/mongod --quiet --config /etc/mongodb.conf (code=exited, status=48)
   Main PID: 1070 (code=exited, status=48)

当我检查 /var/log/mongodb/mongod.log 时，我得到的结果如下：

但是我可以运行 systemctl restart mongodb 并且一切正常

我已经编辑了 /usr/lib/systemd/system/mongodb.service 并添加了以下两行：

Requires=NetworkManager-dispatcher.service NetworkManager.service
After=syslog.target NetworkManager-dispatcher.service NetworkManager.service

因此，价值一百万美元的问题是，我还应该/可以做什么才能使其在启动时正常工作？

感谢您的帮助 ：-）

答案1

您的日志表明该过程已成功启动（最后一行表示成功），但您的服务状态表明它已退出。

日志更有可能是正确的，服务已成功启动，但进程 ID ( PID) 似乎不匹配。您的服务状态为PID1070，日志显示 2916。我怀疑这是您的问题，我主要怀疑原因是选项pidFilePath。查看该文件中实际的内容并尝试删除该选项，看看是否能解决问题。
