MongoDB 启动后告警

在系统上安装mongodb之后报错。 
(安装教程地址: https://docs.mongodb.com/master/tutorial/install-mongodb-on-red-hat/)

 

 

 

 

错误信息: 
WARNING: /sys/kernel/mm/transparent_hugepage/enabled is ‘always’.We suggest setting it to ‘never’ 
WARNING: /sys/kernel/mm/transparent_hugepage/defrag is ‘always’.We suggest setting it to ‘never’

解决方案

前两个warning

 

sudo echo "never" > /sys/kernel/mm/transparent_hugepage/enabled
sudo echo "never" >  /sys/kernel/mm/transparent_hugepage/defrag

第三个warning

vim /etc/security/limits.conf
添加一下几行
mongod  soft  nofile  64000
mongod  hard  nofile  64000
mongod  soft  nproc  32000
mongod  hard  nproc  32000
 

重启mongod

sudo service mongod restart
 

成功
