一、环境说明
1、我们prod环境MongoDB的集群架构是做的分片集群的部署,但是目前我们没有分片,即所有数据都在一个分片上,后期如果数量大,需要分配,集群随时可以分片,对业务方透明
2、各个角色的部署情况
角色 | IP | 端口 | 复制集名称 |
---|---|---|---|
mongos | 172.21.244.101,172.21.244.102,172.21.244.94 | 27000 | 无 |
config server | 172.21.244.101,172.21.244.102,172.21.244.94 | 27100 | repl_configsvr |
存储节点(shard) | 172.21.244.101,172.21.244.102,172.21.244.94 | 27101 | shard1 |
3、MongoDB版本
mongos> db.version() 4.0.4-62-g7e345a7
二、基础信息准备
0、系统优化
echo "never" >/sys/kernel/mm/transparent_hugepage/enabled echo "never" >/sys/kernel/mm/transparent_hugepage/defrag
1、下载MongoDB二进制文件
cd /chj/app wget ops.chehejia.com:9090/pkg/chj_mongodb_4.0.4.tar.gz tar -zxvf chj_mongodb_4.0.4.tar.gz
2、相关目录建立
#建立base目录 mkdir /chj/data/mongodb/chj_db #把MongoDB二进制文件移动到base目录下的bin文件夹 mv chj_mongodb_4.0.4/bin /chj/data/mongodb/chj_db/bin #建立认证文件目录 mkdir /chj/data/mongodb/chj_db/auth #建立配置文件目录 mkdir /chj/data/mongodb/chj_db/conf #建立config server的data和日志目录 mkdir /chj/data/mongodb/chj_db/config/data -p mkdir /chj/data/mongodb/chj_db/config/log #建立mongos的日志目录 mkdir /chj/data/mongodb/chj_db/mongos/log -p #建立数据节点data和日志目录 mkdir /chj/data/mongodb/chj_db/shard1/data -p mkdir /chj/data/mongodb/chj_db/shard1/log
3、相关配置文件编写
A、mongos的配置文件编写
vim /chj/data/mongodb/chj_db/conf/mongos.conf systemLog: destination: file logAppend: true path: /chj/data/mongodb/chj_db/mongos/log/mongos.log processManagement: fork: true # fork and run in background pidFilePath: /chj/data/mongodb/chj_db/mongos/log/mongos.pid # location of pidfile timeZoneInfo: /usr/share/zoneinfo net: port: 27000 bindIpAll: true maxIncomingConnections: 1000 unixDomainSocket: enabled: true pathPrefix: /chj/data/mongodb/chj_db/mongos/log filePermissions: 0700 security: keyFile: /chj/data/mongodb/chj_db/auth/keyfile.key # authorization: enabled #replication: sharding: configDB: repl_configsvr/172.21.244.101:27100,172.21.244.102:27100,172.21.244.94:27100
B、config server的配置文件编写
vim /chj/data/mongodb/chj_db/conf/config.conf systemLog: destination: file logAppend: true path: /chj/data/mongodb/chj_db/config/log/congigsrv.log storage: dbPath: /chj/data/mongodb/chj_db/config/data journal: enabled: true wiredTiger: engineConfig: directoryForIndexes: true processManagement: fork: true # fork and run in background pidFilePath: /chj/data/mongodb/chj_db/config/log/configsrv.pid # location of pidfile timeZoneInfo: /usr/share/zoneinfo net: port: 27100 bindIp: 0.0.0.0 # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting. #bindIpAll: true maxIncomingConnections: 1000 unixDomainSocket: enabled: true pathPrefix: /chj/data/mongodb/chj_db/config/data filePermissions: 0700 security: keyFile: /chj/data/mongodb/chj_db/auth/keyfile.key authorization: enabled replication: replSetName: repl_configsvr sharding: clusterRole: configsvr
C、存储节点的配置文件编写
vim /chj/data/mongodb/chj_db/conf/shard1.conf systemLog: destination: file logAppend: true path: /chj/data/mongodb/chj_db/shard1/log/shard1.log storage: dbPath: /chj/data/mongodb/chj_db/shard1/data journal: enabled: true wiredTiger: engineConfig: directoryForIndexes: true processManagement: fork: true # fork and run in background pidFilePath: /chj/data/mongodb/chj_db/shard1/log/shard1.pid # location of pidfile timeZoneInfo: /usr/share/zoneinfo net: port: 27101 bindIp: 0.0.0.0 # Enter 0.0.0.0,:: to bind to all IPv4 and IPv6 addresses or, alternatively, use the net.bindIpAll setting. #bindIpAll: true maxIncomingConnections: 1000 unixDomainSocket: enabled: true pathPrefix: /chj/data/mongodb/chj_db/shard1/data filePermissions: 0700 security: keyFile: /chj/data/mongodb/chj_db/auth/keyfile.key authorization: enabled replication: replSetName: shard1 sharding: clusterRole: shardsvr
4、生产key认证文件
echo "chj123456" >/chj/data/mongodb/chj_db/auth/keyfile.key #设置文件的权限为400,不然服务无法启动 chmod 400 /chj/data/mongodb/chj_db/auth/keyfile.key
