2.3 启

动MongoDB

ProxmoxVE上新装的CentOS7.4虚拟机，安装MongoDB6。

安装步骤：

2.1 配置yum源

# 创建mongodb yum源（https://www.mongodb.com/docs/manual/tutorial/install-mongodb-on-red-hat/））
[root@host ~]# cd /etc/yum.repos.d/
[root@host yum.repos.d]# vi mongodb-org-6.0.repo
写入
[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
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

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

[root@host ~]# mongosh
Current Mongosh Log ID: 64d0b3d80866e4ace3bc9c6f
Connecting to:          mongodb://127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.10.3
Using MongoDB:          6.0.8
Using Mongosh:          1.10.3

消除2个错误提示

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

完成。
