我无法启动mongodb服务器

Question

我刚刚在Ubuntu16.04上安装了MongoDb，我不能运行服务器。当服务器的"status“(sudo systemctl启动mongodb)时，我得到了以下信息：

lmunoz@lmunoz:/var/www/node/dashboard$ sudo systemctl status mongodb
● mongodb.service - High-performance, schema-free document-oriented 
database
Loaded: loaded (/etc/systemd/system/mongodb.service; enabled; vendor 
preset: enabled)
Active: failed (Result: exit-code) since mar 2017-05-09 12:01:59 PET; 
29s ago
Process: 1042 ExecStart=/usr/bin/mongod --quiet --config 
/etc/mongod.conf (code=exited, status=48)
Main PID: 1042 (code=exited, status=48)

may 09 12:01:59 lmunoz systemd[1]: mongodb.service: Unit entered 
failed state.
may 09 12:01:59 lmunoz systemd[1]: mongodb.service: Failed with result 
'exit-code'.

日志(/var/ log /mongodb/mongod.log)显示了以下内容：

listen(): bind() failed errno:98 Address already in use for socket: 
127.0.0.1:27017
addr already in use
Failed to set up sockets during startup.
dbexit:  rc: 48

我的配置文件(/etc/systemd/system/mongodb.service)包含：

[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target

[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

Answer 1

查看日志，您有另一个服务正在端口27017上运行。

查找该服务并停止它，然后重试。或者，如果您不关心在该端口上运行的服务，可以这样做

sudo fuser -k 27017/tcp

另一种选择是更改mongodb的默认设置。请参阅mongodb how to change default port
