mongodb-3.2.8 单机复制集安装

规划：

replSet 复制集名称： rs1

MongoDB数据库安装安装路径为：/usr/local/mongodb/

复制集成员IP与端口：

节点1： localhost:28010   （默认的primary节点）

节点2： localhost:20811

节点3： localhost:28012

复制集各节点的数据文件，日志文件，私钥文件路径：

节点1： /data/data/r0  , /data/log/r0.log , /data/key/r0

节点2： /data/data/r1  , /data/log/r1.log , /data/key/r1

节点3： /data/data/r2  , /data/log/r2.log , /data/key/r2

$mv mongodb-linux-x86_64-rhel70-3.2.8 mongodb

1） 创建数据文件存储路径

[root@node222 mongodb]# mkdir -p /data02/mongors/data/r0

[root@node222 mongodb]# mkdir -p /data02/mongors/data/r1

[root@node222 mongodb]# mkdir -p /data02/mongors/data/r2

2)创建日志文件路径

[root@node222 mongodb]# mkdir -p /data02/mongors/log

3)创建主从key文件

用于标识集群的私钥的完整路径，如果各个实例的key file内容不一致，程序将不能正常使用

[root@node222 mongodb]# mkdir -p /data02/mongors/key

[root@node222 mongodb]# echo "this is rs1  key" > /data02/mongors/key/r0

[root@node222 mongodb]# echo "this is rs1  key" > /data02/mongors/key/r1

[root@node222 mongodb]# echo "this is rs1  key" > /data02/mongors/key/r2

[root@node222 mongodb]# chmod 600 /data02/mongors/key/r*

4)启动3个实例

依次添加启动参数，其中三个MongoDB实例：

[root@node222 mongodb]# /usr/local/mongodb/bin/mongod --replSet rs1 --keyFile /data02/mongors/key/r0 --fork --port 28010 --dbpath /data02/mongors/data/r0 --logpath=/data02/mongors/log/r0.log --logappend

about to fork child process, waiting until server is ready for connections.

forked process: 16629

child process started successfully, parent exiting

[root@node222 mongodb]# /usr/local/mongodb/bin/mongod --replSet rs1 --keyFile /data02/mongors/key/r1 --fork --port 28011 --dbpath /data02/mongors/data/r1 --logpath=/data02/mongors/log/r1.log --logappend

about to fork child process, waiting until server is ready for connections.

forked process: 16666

child process started successfully, parent exiting

[root@node222 mongodb]# /usr/local/mongodb/bin/mongod --replSet rs1 --keyFile /data02/mongors/key/r2 --fork --port 28012 --dbpath /data02/mongors/data/r2 --logpath=/data02/mongors/log/r2.log --logappend

about to fork child process, waiting until server is ready for connections.

forked process: 16703

child process started successfully, parent exiting

[root@node222 mongodb]#

注：启动命令的参数分别为，mongod为主启动命令， replSet指定复制集名称为rs1，keyfile指定公钥文件 ，fork指定启动方式为deamo后台启动；port指定端口号，dbpath指定数据文件目录，logpath指定日志文件，logappend指定错误日志为日志追加模式；

通过进程和端口，验证启动状态：

[root@node222 mongodb]# ps -ef|grep mongo

root     16629     1  0 17:36 ?        00:00:00 /usr/local/mongodb/bin/mongod --replSet rs1 --keyFile /data02/mongors/key/r0 --fork --port 28010 --dbpath /data02/mongors/data/r0 --logpath=/data02/mongors/log/r0.log --logappend

root     16666     1  0 17:36 ?        00:00:00 /usr/local/mongodb/bin/mongod --replSet rs1 --keyFile /data02/mongors/key/r1 --fork --port 28011 --dbpath /data02/mongors/data/r1 --logpath=/data02/mongors/log/r1.log --logappend

root     16703     1  0 17:36 ?        00:00:00 /usr/local/mongodb/bin/mongod --replSet rs1 --keyFile /data02/mongors/key/r2 --fork --port 28012 --dbpath /data02/mongors/data/r2 --logpath=/data02/mongors/log/r2.log --logappend

root     16739 12972  0 17:37 pts/1    00:00:00 grep --color=auto mongo

[root@node222 mongodb]# netstat -tunlp |grep mong

tcp        0      0 0.0.0.0:28010           0.0.0.0:*               LISTEN      16629/mongod

tcp        0      0 0.0.0.0:28011           0.0.0.0:*               LISTEN      16666/mongod

tcp        0      0 0.0.0.0:28012           0.0.0.0:*               LISTEN      16703/mongod

[root@node222 mongodb]#

5)配置及初始化 Replica Sets

登录到primary服务器上：

# /usr/local/mongodb/bin/mongo -port 28010

配置复制集：

> config = {_id: 'rs1', members: [

{_id: 0, host: 'localhost:28010',priority:1},

{_id: 1, host: 'localhost:28011'},

{_id: 2, host: 'localhost:28012'}]

}

初始化配置，使上面的配置生效：

>  rs.initiate(config);

6)查看复制集状态

> rs.status()

在primary节点上查看复制集状态：

> rs.isMaster()

可以再primary节点进行各种添删改查等各种数据操作，其他非master节点不能进行各种数据操作，也不能发起复制集修改命令

过程如下：（securecrt执行时候总是会复制一下回显）

[root@node222 mongodb]#  /usr/local/mongodb/bin/mongo -port 28010

MongoDB shell version: 3.2.8

connecting to: 127.0.0.1:28010/test
