<h2>Disable Transparent Huge Pages</h2>
通过启动脚本可以在每次启动时关闭THP
vim /etc/init.d/disable-transparent-hugepages
#以下为脚本内容
#!/bin/bash
### BEGIN INIT INFO

      thp_path=/sys/kernel/mm/redhat_transparent_hugepage

<h1>1、Install the Ops Manager Application Database</h1>
Ops Manager需要先安装mongodb，创建其数据库副本集后才能部署安装。
官方的yum源比较慢，推荐使用阿里云yum源
# 阿里云repo
cat > /etc/yum.repos.d/mongodb-org-3.4.repo << EOF

name=MongoDB Repository
#baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/3.4/x86_64/
baseurl=https://mirrors.aliyun.com/mongodb/yum/redhat/\$releasever/mongodb-org/3.4/x86_64/
gpgcheck=0
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-3.4.asc
EOF
 
<h2>安装mongod</h2>
在每台节点上执行以下步骤
yum install -y mongodb-org
修改配置
vim /etc/mongod.conf
#修改为数据分区，需创建该目录，并确保mongod用户可读写
# Where and how to store data.
storage:
  dbPath: /data/mongo  
  journal:
    enabled: true
 
#默认监听本地lo，注释掉
# network interfaces
net:
  port: 27017
#  bindIp: 127.0.0.1  # Listen to local interface only, comment to listen on all interfaces.
启动服务
mkdir -p /data/mongo
chown -R mongod:mongod /data
systemctl start mongod.service
 
<h2>部署Ops Manager副本集</h2>
通过修改配置文件的方式创建Ops Manager所需副本集。
注：也可以通过命令行方式指定副本集启动。修改配置文件的方式便于通过init script管理。
在所有节点上修改配置
vim mongod.conf
#添加以下内容
replication:
  replSetName: rs_ops_manager
 
#重启生效
systemctl start mongod.service
在任一节点上执行mongo shell，添加副本集节点，此处使用node1节点
mongo --host localhost --port 27017
 
#Initiate the replica set
rs.initiate()
#display the replica set configuration object
rs.conf()
#Add the remaining members to the replica set
rs.add("mydb2")
rs.add("mydb3")
#Check the status of the replica set
rs.status()
 
<h1>2、Install Ops Manager</h1>
#下载安装wget -c https://downloads.mongodb.com/on-prem-mms/rpm/mongodb-mms-3.4.15.646-1.x86_64.rpm
rpm -ivh mongodb-mms-<version>.x86_64.rpm
Configure the Ops Manager connection to the Ops Manager Application Database
vim /opt/mongodb/mms/conf/conf-mms.properties
#设置mongo.mongoUri
mongo.mongoUri=mongodb://mydb1:27017,mydb2:27017,mydb3:27017/?replicaSet=rs_ops_manager /etc/init.d/mongodb-mms start

<h1>3、配置MongoDB Ops Manager</h1>
3.1 打开Ops管理界面
通过服务ops的8080端口，即可打开web管理界面，如下图所示:
