mongodb - Replication Set搭建过程

1.创建目录

?

1 2 3 4

mkdir -p /mongodb/data/r1 mkdir -p /mongodb/data/r2 mkdir -p /mongodb/data/r3 mkdir -p /mongodb/mlog

2.启动三个实例，并声明实例属于复制集

?

1 2 3

./mongod --dbpath /mongodb/data/r1  --logpath /mongodb/mlog/r1.log --fork --port 27017 --replSet ybb --smallfiles ./mongod --dbpath /mongodb/data/r2  --logpath /mongodb/mlog/r2.log --fork --port 27018 --replSet ybb --smallfiles ./mongod --dbpath /mongodb/data/r3  --logpath /mongodb/mlog/r3.log --fork --port 27019 --replSet ybb --smallfiles

3.复制集初始化
这一步初始化的复制集只是包含当前节点

?

1 2 3 4 5 6 7

# ./mongo --port=27017 > rs.initiate() {         "info2" : "no configuration specified. Using a default configuration for the set",         "me" : "cc.example.com:27017",         "ok" : 1 }

4.验证复制集初始化配置

这一步初始化的复制集只是包含当前节点

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

ybb:OTHER> rs.conf() {         "_id" : "ybb",         "version" : 1,         "protocolVersion" : NumberLong(1),         "members" : [                 {                         "_id" : 0,                         "host" : "cc.example.com:27017",                         "arbiterOnly" : false,                         "buildIndexes" : true,                         "hidden" : false,                         "priority" : 1,                         "tags" : {                           },                         "slaveDelay" : NumberLong(0),                         "votes" : 1                 }         ],         "settings" : {                 "chainingAllowed" : true,                 "heartbeatIntervalMillis" : 2000,                 "heartbeatTimeoutSecs" : 10,                 "electionTimeoutMillis" : 10000,                 "getLastErrorModes" : {                   },                 "getLastErrorDefaults" : {                         "w" : 1,                         "wtimeout" : 0                 }         } } ybb:PRIMARY>

5.添加其它节点

?

1 2 3 4 5

ybb:PRIMARY> rs.add("cc.example.com:27018")rs.add("cc.example.com:27018") { "ok" : 1 } ybb:PRIMARY> rs.add("cc.example.com:27019")rs.add("cc.example.com:27019") { "ok" : 1 } ybb:PRIMARY>

6.检查复制集的状态

7.查看复制集的最新配置

?
