开始部署​

MongoDB Replica Set Node01​

  1. 下载 mongodb 安装包并解压到安装目录

    wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.4.29.tgz
    tar -zxvf mongodb-linux-x86_64-rhel70-4.4.29.tgz
    mv mongodb-linux-x86_64-rhel70-4.4.29 /usr/local/mongodb

  2. 创建 mongodb 用户

    useradd -M -s /sbin/nologin mongodb

  3. 创建数据、日志目录并授予权限

    mkdir -p /data/mongodb/ /data/logs/mongodb
    echo '1/3GWm7LjfCX/K2NOhv0evgBWan+KNX' > /data/mongodb/keyfile
    chmod 400 /data/mongodb/keyfile
    chown -R mongodb:mongodb /usr/local/mongodb/ /data/mongodb/ /data/logs

  4. 配置 systemd 管理文件

    cat > /etc/systemd/system/mongodb.service <<EOF
    [Unit]
    Description=MongoDB
    [Service]
    User=mongodb
    Group=mongodb
    LimitNOFILE=1000000
    LimitNPROC=1000000
    ExecStart=/usr/local/mongodb/bin/mongod --logpath /data/logs/mongodb/mongodb.log --dbpath /data/mongodb --auth --keyFile /data/mongodb/keyfile --port 27017 --replSet local-mongodb-one --bind_ip 0.0.0.0
    ExecStop=/usr/bin/kill \$MAINPID
    Restart=on-failure
    [Install]
    WantedBy=multi-user.target
    EOF

  5. 加入开机自启动

    # 安装后还没创建用户，所以先不用 systemctl start mongodb 启动服务
    systemctl daemon-reload
    systemctl enable mongodb

创建数据库用户​

在 MongoDB Replica Set Node01 节点上操作

  1. 临时启动一个未开启连接认证的 mongodb 服务

    su -c '/usr/local/mongodb/bin/mongod --fork --logpath /data/logs/mongodb/mongodb.log --dbpath /data/mongodb --noauth  --port 27017' -s /bin/bash mongodb

  2. 创建用户

    • 命令中指定的 mongodb admin 库权限 root 用户密码为 12345678 ，实际部署时注意替换
    • 命令中指定的 mongodb 业务库权限 mingdao 用户密码为 123456 ，实际部署时注意替换

  3. 关闭临时启动的 MongoDB

    kill $(pgrep -f 'mongod')

启动 MongoDB​

三台部署 mongodb 的服务器上操作

systemctl start mongodb

配置副本集​

在 MongoDB Replica Set Node01 节点上操作

  1. 登录 mongodb

    /usr/local/mongodb/bin/mongo -u root -p 12345678 --authenticationDatabase admin

  2. 配置副本集

    rs.initiate({_id: "local-mongodb-one",members:[ {_id : 1, host : "192.168.10.4:27017"},{_id : 2, host : "192.168.10.5:27017"},{_id : 3, host : "192.168.10.6:27017"} ]})
    • rs.initiate 语句中的各节点IP，在实际部署时注意替换

  3. 确认副本集状态

    rs.status()

    # 输出结果中，正常为一个节点 PRIMARY，两个 SECONDARY 状态
