Detailed MongoDB master configuration _mongodb

One, MongoDB master server

192.168.1.5 MongoDB Primary Server
192.168.1.108 MongoDB from server

Second, MongoDB master server installation

[Root@localhost ~]# yum install Php-pecl-mongo MongoDB mongodb-devel mongodb-server 

Third, master-slave server configuration

1, Primary server 192.168.1.5 configuration

[Root@localhost ~]# cat/etc/mongodb.conf |awk ' {if ($!~/^$/&& $!~/^#/) {print $}} ' 
logpath=/var/log/mo Ngodb/mongodb.log 
fork = True 
logappend=true 
dbpath=/var/lib/mongodb 
pidfilepath=/var/run/ Mongodb/mongodb.pid 
master = true 
Source = 192.168.1.108 

Create a database directory

[Root@localhost lib]# mkdir-p/var/lib/mongodb [root@localhost lib]# chown mongodb:mongodb-r/var/lib/mongodb/ 
 

2, 192.168.1.108 configuration from server

[Root@localhost ~]# cat/etc/mongodb.conf |awk ' {if ($!~/^$/&& $!~/^#/) {print $}} ' 
logpath=/var/log/mo Ngodb/mongodb.log 
logappend=true 
fork = true 
port = 27017 
dbpath=/var/lib/mongodb 
pidfilepath= /var/run/mongodb/mongodb.pid 
slave = true 
Source = 192.168.1.5 

Create a database directory

[Root@localhost lib]# mkdir-p/var/lib/mongodb [root@localhost lib]# chown mongodb:mongodb-r/var/lib/mongodb/ 
 

There is a only in the original configuration, which can be used for selective synchronization of data, Only=test, to synchronize only the test database

3, start the master-slave server MongoDB

[Root@localhost www]#/etc/init.d/mongod start 

Four, test synchronization

Primary server 192.168.1.5

<?php 
$m = new Mongo (); 
$db = new MongoDB ($m, ' mydbname '); 
$log = $db->createcollection ("Logger", true, 10*1024); 
 
for ($i = 0; $i < 5 $i + +) { 
 $log->insert (Array ("Level" => WARN, "msg" => "Zhang Ying log Message # $i", "TS" => New Mongodate ()); 
} 
 
$msgs = $log->find (); 
 
foreach ($msgs as $msg) { 
 echo $msg [' msg ']. " <br> "; 
} 
$dbs = $m->listdbs (); 
 
Print_r ($dbs); 
 
? > 

192.168.1.108 from server

<?php 
$m = new Mongo (); 
$db = new MongoDB ($m, ' mydbname '); 
$log = $db->createcollection ("Logger", true, 10*1024); 
 
$msgs = $log->find (); 
 
foreach ($msgs as $msg) { 
 echo $msg [' msg ']. " <br> "; 
} 
$dbs = $m->listdbs (); 
 
Print_r ($dbs); 
 
? > 

If the display is the same, it means that the synchronization is successful, and we can also see if the synchronization is successful in other ways.

View the path to the database below the file is not the same size is not the same.

[Root@localhost www]# ll/var/lib/mongodb/

If all the same, it means that the synchronization is successful.

We can also view the log log to see if the synchronization was successful.
