技術標籤：MongoDB實踐mongodb

一、安裝

下載地址：https://www.mongodb.com/try/download/community
下載的包名為：mongodb-linux-x86_64-4.0.21.tgz
解壓：

[[email protected] ~]# tar -zxf mongodb-linux-x86_64-4.0.21.tgz

建立執行MongoDB的普通使用者：

[[email protected] ~]# useradd mongod
[[email protected] ~]# passwd mongod

建立需要的目錄：

[
 
[email protected] ~]# mkdir -p /usr/local/mongodb/{conf,data,log}

將解壓出來的bin目錄，移動到/usr/local/mongodb目錄下：

[[email protected] ~]# mv mongodb-linux-x86_64-4.0.21/bin/ /usr/local/mongodb/
[email protected] ~]# ls /usr/local/mongodb/
bin  conf  data  log

修改目錄許可權：

[[email protected] ~]# chown -R mongod:mongod /usr/local/mongodb/
 

設定環境變數：

[[email protected] ~]# vim /etc/profile.d/mongod.sh
export PATH=/usr/local/mongodb/bin:$PATH
[[email protected] ~]# source /etc/profile

二、配置檔案

MongoDB的配置檔案，遵循YAML格式：

[[email protected] ~]# vim /usr/local/mongodb/conf/mongodb.conf
# 日誌相關
systemLog:
  destination: file
  logAppend: true
  path: /usr/local/mongodb/log/mongodb.log

# 資料儲存相關
storage:
  dbPath: /usr/local/mongodb/data
  journal:
    enabled: true

# 程序控制
processManagement:
  fork: true
  pidFilePath: /usr/local/mongodb/data/mongodb.pid
  timeZoneInfo: /usr/share/zoneinfo

# 網路配置相關
net:
  port: 27017
  bindIp: 0.0.0.0
 

官方推薦使用普通使用者執行MongoDB，啟動MongoDB：

[[email protected] ~]# su - mongod
[[email protected] ~]$ mongod -f /usr/local/mongodb/conf/mongodb.conf

停止MongoDB：

[[email protected] ~]$ mongod -f /usr/local/mongodb/conf/mongodb.conf --shutdown

三、使用systemd管理MongoDB

[[email protected] ~]# vim /usr/lib/systemd/system/mongod.service
[Unit]
Description=MongoDB 4.0.21

[Service]
User=mongod
Restart=on-failure
Type=forking
ExecStart=/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongodb.conf
ExecStop=/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/conf/mongodb.conf --shutdown
ExecReload=/bin/kill -s HUP $MAINPID

[Install]
WantedBy=multi-user.target

使用systemd啟動MongoDB：

[[email protected] ~]# systemctl daemon-reload   #更新配置
[[email protected] ~]# systemctl enable mongod   #開機自啟動
[[email protected] ~]# systemctl start mongod    #啟動MongoDB
[[email protected] ~]# systemctl status mongod   #檢視MongoDB狀態
