centos 7 mongodb无法启动

Question

我在 Centos 7 上安装了 mongodb，一切正常。

但是如果我重新启动系统，mongodb 就无法启动了。如果我卸载并再次安装，效果很好。但重启后就无法启动了。

当我尝试 systemctl status mongod.service 显示:

mongod.service - High-performance, schema-free document-oriented database Loaded: loaded (/usr/lib/systemd/system/mongod.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Dom 2016-11-27 09:49:36 BRT; 12min ago Docs: https://docs.mongodb.org/manual Process: 1471 ExecStart=/usr/bin/mongod $OPTIONS run (code=exited, status=1/FAILURE) Main PID: 1471 (code=exited, status=1/FAILURE)

Nov 27 09:49:36 localhost.localdomain systemd[1]: mongod.service failed.

我已经尝试过:

*chcon -R -t mongod_var_lib_t /var/lib/mongo
*SElinux=disable
*chmod 7777 /var/lib/mongo
and nothing.

我记得在格式化我的电脑之前出现此错误时，我需要使用一个简单的命令对 systemd 授予权限。但我再也找不到了。

这是官方错误报告 https://jira.mongodb.org/browse/SERVER-27241

在

 /usr/lib/systemd/system/mongod.service

使用以下内容更新 systemd 服务，直到他们正式修复为止

    [Service]
    User=mongod
    Group=mongod
    Environment="OPTIONS=--quiet -f /etc/mongod.conf"
    PermissionsStartOnly=true
    ExecStartPre=/usr/bin/mkdir /var/run/mongodb
    ExecStartPre=/usr/bin/chown -R mongod:mongod /var/run/mongodb
    ExecStart=/usr/bin/mongod $OPTIONS run
    PIDFile=/var/run/mongodb/mongod.pid
