【已解决】mongo启动失败:connection /var/lib/mongo/WiredTiger.turtle handle-open open Permission denied

折腾:
【已解决】添加了IP限制的mongod重启出错:Job for mongod.service failed because the control process exited with error code
期间,虽然解决了之前的sock文件的问题:
【已解决】mongo启动失败:Failed to unlink socket file /tmp/mongodb-xxx.sock errno 1 Operation not permitted
而且也已经去掉了:
在bindIp中尝试添加外网的客户端的IP的错误做法
但是却又出现别的问题:

即:

算了,暂时不去为了,mongo所在服务器的局域网的其他后期可能存在的服务器能访问此服务器了。
所以去掉这个IP,只保留127.0.0.1:
vi /etc/mongod.conf

     27 net:
     28   port: 32018
     29   bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.
重启服务器,结果错误依旧:

“I’m having problems lauching mongod as a service: How is it possible that it works when I do sudo mongod -f /etc/mongod.conf but when launching it with sudo service mongod start I get an error in the log”
和我遇到的一样:
重启服务器:会自动尝试去启动mongod
但是服务器已经启动后,用root用户通过ssh进去服务器后,去用service启动mongod,结果都没有反应,不起作用
此处,其主要提到的是文件的权限问题。
而我此处也是,去看看文件权限,还果然是,有几个文件是root,而不是mongod:

然后再去重启mongod服务,这下:
不用reboot重启CentOS
也不用,直接以root去运行mongod
而是参考解释,去以特定的mongod用户去运行mongod:
[root@xxx-general-01 ~]# sudo -u mongod mongod -f /etc/mongod.conf
about to fork child process, waiting until server is ready for connections.
forked process: 1290

看log,又是权限问题:

去看看出了问题的文件:

-rw-r--r-- 1 mongod mongod 100M Apr 10 15:17 /var/lib/mongo/journal/WiredTigerLog.0000000116
再去更改root为mongod用户:

[root@xxx-general-01 ~]# ll -lha /var/lib/mongo/journal/*

再去启动看看
[root@xxx-general-01 ~]# sudo -u mongod mongod -f /etc/mongod.conf      
about to fork child process, waiting until server is ready for connections.

终于是可以正常启动了。
【总结】
此处,mongo启动失败:
[initandlisten] WiredTiger (13) [1523342727:918317][1096:0x7f9d668e4dc0], file:WiredTiger.wt, connection: /var/lib/mongo/WiredTiger.turtle: handle-open: open: Permission denied
和:
[initandlisten] WiredTiger (13) [1523344670:293798][1290:0x7f726ee76dc0], txn-recover: /var/lib/mongo/journal/WiredTigerLog.0000000115: handle-open: open: Permission denied
的原因是:
之前的某次通过root去启动mongo,导致生成了所有者owner是root的文件:
/var/lib/mongo/WiredTiger.turtle
/var/lib/mongo/journal/WiredTigerLog.0000000115
从而在mongo服务通过mongod这个用户去启动时,没有权限访问。
解决办法是:
把对应的文件的所有者改回给mongod:
chown mongod:mongod /var/lib/mongo/WiredTiger.turtle
chown mongod:mongod /var/lib/mongo/WiredTigerLAS.wt 
chown mongod:mongod /var/lib/mongo/journal/*
即可正常(在当前登录用户root的情况下,换用mongd的用户去)启动mongod:
sudo -u mongod mongod -f /etc/mongod.conf
了。
