mongoDB错误代号48、100的解决方案

今天在安装mongodb后一直报错，说是错误100，没有权限。

错误信息如下

解决方案如下

rm -rf /usr/local/var/mongodb
brew uninstall --force mongodb
brew install mongodb

解决后又有新的问题

说是48号错误。

观察后发现是端口没有关闭

查看使用某端口的进程

最简单的命令是：
lsof -i :端口号

使用losf -i :27010
得到如下结果

➜  ~ lsof -i:27017
COMMAND   PID   USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
mongod  15387 hikalu    6u  IPv4 0x46420325c7e84b01      0t0  TCP *:27017 (LISTEN)

关闭某进程的命令

sudo kill -9 PID
mongodb的PID是15387
执行➜ ~ sudo kill -9 15387就可以关闭
