准备基本环境

服务器node1(10.0.3.1) 服务器node2(10.0.3.2) 服务器node3(10.0.3.3)
mongos 20000 mongos 20000 mongos 20000
config server 21000 config server 21000 config server 21000
shard server1 主节点27001 shard server1 副节点 27001 shard server1 仲裁27001
shard server2 仲裁27002 shard server2 主节点27002 shard server2 副节点27002
shard server3 副节点27003 shard server3 仲裁27003 shard server3 主节点27003

搭建步骤

三台设备均操作

  • 3台设备修改 hosts 文件
[mongod@mongodb-node-1 ~]$ cat /etc/hosts
10.0.3.1	mongodb-node-1
10.0.3.2	mongodb-node-2
10.0.3.3	mongodb-node-3
  • 3台设备创建数据目录和日志目录
[mongod@mongodb-node-1 ~]$ mkdir -p /export/mongodb-4.4.18/cluster/{config,mongos,shard1,shard2,shard3}/{data,logs}
  • 3台设备安装mongodb tar包所需依赖
[mongod@mongodb-node-1 ~]$ yum install -y libcurl openssl xz-libs
  • 3台设备下载mongodb二进制包并解压
[root@mongodb-node-1 ~]#  wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-4.4.18.tgz 
[root@mongodb-node-1 ~]# tar -xf mongodb-linux-x86_64-rhel70-4.4.18.tgz -C /export/
[root@mongodb-node-1 ~]# cd /export/
[root@mongodb-node-1 export]# mv mongodb-linux-x86_64-rhel70-4.4.18 mongodb-4.4.18
  • 3台设备配置环境变量
[root@mongodb-node-1 export]# cat /etc/profile.d/mongodb.sh 
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/export/mongodb-4.4.18/bin

source /etc/profile.d/mongodb.sh
mongo --version
  • 3台设备创建mongodb启动用户
[root@mongodb-node-1 ~]# useradd  -d /export/mongod mongod
[root@mongodb-node-1 ~]# chown mongod:mongod /export/mongodb-4.4.18/ -R
