创建目录(三个节点相同)

mkdit -p /data/mongodb/{data,log,key}

key的生成与权限(一个节点生成，拷贝到其他节点，权限要保证为400或者600)

openssl rand -base64 100 > /data/mongodb/key/key

chmod 600 /data/mongodb/key/key

scp /data/mongodb/key/key user@10.110.18.90:/data/mongodb/key/

scp /data/mongodb/key/key user@10.110.18.94:/data/mongodb/key/

启动mongodb实例(三个节点相同)

/usr/local/mongodb/bin/mongod -f /usr/local/mongodb/etc/mongod.conf

登陆最先启动的节点，初始化replset成员，并增加管理用户

/usr/local/mongodb/bin/mongo --host 127.0.0.1 --port 27017

rs.initiate(

　　{

　　_id: "pandatv_msg",

　　version: 1,

　　members: [

　　{ _id: 0, host : "10.110.18.89 :27017" },

　　{ _id: 1, host : "10.110.18.90 :27017" },

　　{ _id: 2, host : "10.110.18.94 :27017" }

　　]

　　})

use admin

db.createUser(

　　{

　　user: "admin",

　　pwd: "password",

　　roles: [ { "role" : "dbAdminAnyDatabase", "db" : "admin" }, { "role" : "userAdminAnyDatabase", "db" : "admin" }, { "role" : "clusterAdmin", "db" : "admin" }, { "role" : "readWriteAnyDatabase", "db" : "admin" } ]

　　}

　　)

use test

db.createUser(

{

user: "notify",

pwd: "password",

roles: [ { "role" : "dbOwner", "db" : "notify" } ]

}

)

至此，安装完成，看下replset状态

rs.status()

登陆其他节点验证

/usr/local/mongodb/bin/mongo --host 10.110.18.94 --port 27017 admin -uadmin -p

rs.status()

/usr/local/mongodb/bin/mongo --host 10.110.18.90 --port 27017 admin -uadmin -p

rs.status()
