1、环境描述
172.18.62.23 node1 shard服务器 172.18.62.24 node2 shard服务器 172.18.62.25 node3 配置服务器 172.18.62.26 node4 配置服务器 172.18.62.27 node5 路由服务器
2、启动容器
bs create mongodb bs ps
3、进入容器
docker exec -it mongodb_node1_1 bash docker exec -it mongodb_node2_1 bash docker exec -it mongodb_node3_1 bash docker exec -it mongodb_node4_1 bash docker exec -it mongodb_node5_1 bash
4、分别在容器安装mongodb
apt update apt upgrade apt install mongodb -y
5、修改配置文件
node1
dbpath=/var/lib/mongodb logpath=/var/log/mongodb/mongodb.log logappend=true bind_ip = 0.0.0.0 port = 27017 shardsvr=true journal=true
node2
dbpath=/var/lib/mongodb logpath=/var/log/mongodb/mongodb.log logappend=true bind_ip = 0.0.0.0 port = 27017 shardsvr=true journal=true
启动服务
/etc/init.d/mongodb start
node3
dbpath=/var/lib/mongodb logpath=/var/log/mongodb/mongodb.log logappend=true bind_ip = 0.0.0.0 port = 27017 replSet = configsrv/172.18.62.26:27017 configsvr=true journal=true
node4
dbpath=/var/lib/mongodb logpath=/var/log/mongodb/mongodb.log logappend=true bind_ip = 0.0.0.0 port = 27017 replSet = configsrv/172.18.62.25:27017 configsvr=true journal=true
启动服务
/etc/init.d/mongodb start
初始化副本集
>config =
{
_id: 'configsrv',
members:
[
{
"_id":1,
"host":"172.18.62.25:27017",
priority: 3
},
{
"_id":2,
"host":"172.18.62.26:27017",
priority: 2
}
]
}
node5
logpath=/var/log/mongodb/mongodb.log logappend=true bind_ip = 0.0.0.0 port = 27017 configdb=configsrv/172.18.62.25:27017,172.18.62.26:27017
启动服务
mongos -f /etc/mongodb.conf &
root@mongodb-node5:~# netstat -antp |grep mongo tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 1187/mongos tcp 0 0 172.18.62.27:39072 172.18.62.25:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:39062 172.18.62.25:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:39074 172.18.62.25:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:44610 172.18.62.26:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:44616 172.18.62.26:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:44620 172.18.62.26:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:44614 172.18.62.26:27017 ESTABLISHED 1187/mongos tcp 0 0 172.18.62.27:39068 172.18.62.25:27017 ESTABLISHED 1187/mongos
5、登录路由服务器，添加分片服务器
use admin
db.runCommand({addshard: "172.18.62.23:27017",allowLocal:true})
db.runCommand({addshard: "172.18.62.24:27017",allowLocal:true})
6、在路由服务器上设置针对哪个数据库进行分片
db.runCommand({enablesharding: "testdb"})
db.runCommand({shardcollection: "testdb.tb01",key:{id:1}})
7、测试结果，连接路由服务器存储数据
use testdb
function add(){
for(var i=0;i<20000;i++){
db.tb01.insert({"id":i+10,"name":"jim"})
}
}
add()
8、查看分片
use testdb sh.status()
mongos> sh.status()
