【MongoDB】启动
1：命令行：
注：dbpath默认为/data/db，当存在/data/db时，那么无需使用dbpath参数，否则，必须制定dbpath的具体路径

2：Daemon
注意：
1）Daemon方式启动，需要使用“–fork”参数，如果使用了“–fork”参数，那么就必须启用“–logpath”参数，没有商量余地
2）“–logpath”指定的目录必须提前创建好

1 2 3 4 5 6 7 8 9 10 11 12 |
[mdb@xxf ~]$ mkdir -p /data/log [mdb@xxf ~]$ [mdb@xxf ~]$ ls -l /data total 8 drwxr-xr-x 4 mdb mdb 4096 Jan 9 15:06 db drwxr-xr-x 2 mdb mdb 4096 Jan 9 15:04 log [mdb@xxf ~]$ [mdb@xxf ~]$ mongod --logpath=/data/log/L.log --fork about to fork child process, waiting until server is ready for connections. forked process: 3529 child process started successfully, parent exiting [mdb@xxf ~]$ |
3：配置文件
1）常看刚刚创建好的配置文件
|
1 2 3 4 5 |
[mdb@xxf ~]$ cat mongodb.cfg dbpath=/data/db/ logpath=/data/log/L.log [mdb@xxf ~]$ |
2）利用配置文件启动数据库
|
1 2 3 4 5 |
[mdb@xxf ~]$ mongod -f mongodb.cfg -fork about to fork child process, waiting until server is ready for connections. forked process: 4452 child process started successfully, parent exiting [mdb@xxf ~]$ |
或者
|
1 2 3 4 5 |
[mdb@xxf ~]$ mongod --config mongodb.cfg -fork about to fork child process, waiting until server is ready for connections. forked process: 4500 child process started successfully, parent exiting [mdb@xxf ~]$ |
