建立資料庫資料夾以及日誌資料夾

[root@localhost mongodb]# pwd
/usr/local/mongodb
[root@localhost mongodb]# mkdir -p data
[root@localhost mongodb]# mkdir -p log
[root@localhost mongodb]# touch log/mongodb.log
[root@localhost mongodb]# 

建立資料庫配置檔案

在 /usr/local/mongodb/bin 路徑下建立資料庫配置檔案mongodb.conf，並新增以下內容

# 資料庫路徑
dbpath=/usr/local/mongodb/data
# 日誌檔案路徑
logpath=/usr/local/mongodb/log/mongodb.log
# 表示日誌檔案末尾追加日誌
logappend=true
# 啟用埠號
port=27017
# 是否在後臺執行
fork=true

看到以上資訊證明mongoDB安裝成功

啟動mongoDB

root@localhost:/usr/local/mongodb/bin# mongod -f ./mongodb.conf
about to fork child process, waiting until server is ready for connections.
forked process: 1302
child process started successfully, parent exiting

看到以上訊息代表啟動成功

登入mongoDB

./mongo   登入

關閉mongoDB服務

注意：關閉的時候一定要正常關閉，否則下次會無法啟動服務，並且報錯。

這是我未正常關閉的後果，服務無法啟動，報錯如下：

about to fork child process, waiting until server is ready for connections.
forked process: 1268
ERROR: child process failed, exited with error number 1
To see additional information in this output, start without the "--fork" option.

正常關閉步驟：

> use admin
switched to db admin
> db.shutdownServer();
