linux环境下mongodb启动报错 ：Job for mongodb.service failed because the control process exited with error

使用在启动mongodb 时报如下错误：

Job for mongodb.service failed because the control process exited with error code. See "systemctl status mongodb.service" and "journalctl -xe" for details.

[root@jt-server1 mongodb]# systemctl start mongodb.service
Job for mongodb.service failed because the control process exited with error code. See "systemctl status mongodb.service" and "journalctl -xe" for details.

运行 journalctl -xe ，查看错误日志，看到：

Feb 25 10:35:15 jt-server1 mongod[26053]: Error reading config file: No such file or directory
Feb 25 10:35:15 jt-server1 mongod[26053]: try '/opt/soft/mongodb/bin/mongod --help' for more information
接着去检查 mongodb.service文件

[Unit]  
  
Description=mongodb   
After=network.target remote-fs.target nss-lookup.target  
  
[Service]  
Type=forking  
ExecStart=/opt/soft/mongodb/bin/mongod --config /soft/mongodb/mongodb.conf  
ExecReload=/bin/kill -s HUP $MAINPID  
ExecStop=/opt/soft/mongodb/bin/mongod --shutdown --config /soft/mongodb/mongodb.conf  
PrivateTmp=true  
    
[Install]  
WantedBy=multi-user.target 

发现文件中配置的mongodb.conf 文件目录错误，修改正确后如下：

[Unit]  
  
Description=mongodb   
After=network.target remote-fs.target nss-lookup.target  
  
[Service]  
Type=forking  
ExecStart=/opt/soft/mongodb/bin/mongod --config /opt/soft/mongodb/mongodb.conf

ExecStop=/opt/soft/mongodb/bin/mongod --shutdown --config /opt/soft/mongodb/mongodb.conf  
PrivateTmp=true  
    
[Install]  
WantedBy=multi-user.target 

重新加载配置systemctl daemon-reload后，启动成功！！！
