mongo启动异常-mongodb exception in initAndListen: 7026old lock file, terminating

来源：互联网发布：java写九九乘法表编辑：程序博客网时间：2024/06/05 15:52

刚安装上mongo时, 第一次可以启动成功, 第二次的时候就启动不了, 发现没有启动的时候 data下面多了 mongod.lock文件, 里面有个数字, 正常情况下关闭mongo时该文件大小应该为 0KB

对应的log信息如下:

注意加红的的部分: 问题就出现在这个 lock文件上.

解决办法: 删掉lock文件, 在mongo bin 目录下运行mongod.exe --repair , 然后启动mongo, OK.
