创建目录(三个节点相同)
mkdit -p /data/mongodb/
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

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
