ProxmoxVE上新装的CentOS7.4虚拟机，安装MongoDB6。

安装步骤：

2.1 配置yum源

1.  
   # 创建mongodb yum源（https://www.mongodb.com/docs/manual/tutorial/install-mongodb-on-red-hat/））
2.  
   [root@host ~]# cd /etc/yum.repos.d/
3.  
   [root@host yum.repos.d]# vi mongodb-org-6.0.repo
4.  
   写入
5.  
   [mongodb-org-6.0]
6.  
   name=MongoDB Repository
7.  
   baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
8.  
   gpgcheck=1
9.  
   enabled=1
10.  
    gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc

2.2 安装MongoDB

[root@host yum.repos.d]# yum install -y mongodb-org

2.3 启

动MongoDB

[root@host yum.repos.d]# systemctl start mongod

启动MongoDB，测试mongosh连接时连接报错

1.  
   [root@host yum.repos.d]# mongosh
2.  
   Current Mongosh Log ID: 64d1c1a5ad16cdb9245f8893
3.  
   Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh 1.10.3
4.  
   MongoNetworkError: connect ECONNREFUSED 127.0.0.1:27017
5.  
   [root@host yum.repos.d]#

参照MongoDB官方文档，将CPU模式改为SandyBridge

重启服务器后，再次启动mongo，成功

1.  
   [root@host ~]# mongosh
2.  
   Current Mongosh Log ID: 64d0b3d80866e4ace3bc9c6f
3.  
   Connecting to: mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh 1.10.3
4.  
   Using MongoDB: 6.0.8
5.  
   Using Mongosh: 1.10.3
6.  
    
7.  
   For mongosh info see: https://docs.mongodb.com/mongodb-shell/

消除2个错误提示

1.  
   [root@host ~]# echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
2.  
   [root@host ~]# echo "never" > /sys/kernel/mm/transparent_hugepage/defrag
3.  
   [root@host ~]# systemctl stop mongod
4.  
   [root@host ~]# systemctl start mongod

完成。
