PHP的mongodb扩展

在这里插入图片描述
在这里插入图片描述
1)下载最新的PHP MongoDB扩展源码，源码可以在
http://pecl.php.net/package/mongo下载.
2）解压,进入安装目录
wget http://pecl.php.net/get/mongo-1.5.4.tgz
tar -zxvf mongo-1.5.4.tgz
cd mongo-1.5.4
3)进入文件夹后，首先运行phpize来编译扩展的环境
[root@localhost mongo-1.5.4]# phpize
Configuring for:
PHP Api Version: 20121113
Zend Module Api No: 20121212
Zend Extension Api No: 220121212
3) cd
4)运行后，我们运行./configure脚本来进行配置
./configure --with-php-config=/usr/local/php/bin/php-config && make && make install
–with-php-config 这个参数是告诉配置脚本 php-config 这个程序的路径
5)完成后，请编辑你php.ini文件增加一行 /usr/local/php/etc/php.ini
extension=mongo.so
一般默认的编译php的ini文件/usr/local/php/etc/php.ini
重启Apache/Nginx[或者/etc/init.d/php-fpm restart打开 phpinfo
看到mongo模块，证明MongoDB的php扩展安装成功。
二.PHP的mongo的扩展
1、安装mongo扩展
wget http://pecl.php.net/get/mongo-1.6.11.tgz
tar zxvf mongo-1.6.11.tgz
cd mongo-1.6.11
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config
make && make install

32位系统在 Installing shared extensions:     /usr/lib/php/modules/
64位系统在 Installing shared extensions:     /usr/lib64/php/modules/
2、php加载扩展
vi /etc/php.ini 
extension_dir = "/usr/lib64/php/modules"
extension="mongo.so"
:wq!  保存退出
3、重新加载php-fpm
service php-fpm reload
## Mongodb副本集

## Mongodb副本集搭建
以mongo1为主库，mongo2，mongo3为从库进行集合搭建。设定mongo1中原本有数据
在mongo1建测试数据
进入mongo1的数据库 
并在数据库中新建了一个集合test并在其中插入一条数据

[root@localhost ~]# mongo

删除mongo2，mongo3中的所有数据库
分别进入mongo2，mongo3 
删除所有数据库（包括admin和local）

创建集合
分别在mongo1，mongo2和mongo3上启动命名为sbc的mongod服务

mongo1：

[root@localhost ~]# mongod --replSet sbc -f /etc/mongod.conf --fork
about to fork child process, waiting until server is ready for connections.
forked process: 73721
child process started successfully, parent exiting

mongo2：

[root@localhost ~]# mongod --replSet sbc -f /etc/mongod.conf --fork
about to fork child process, waiting until server is ready for connections.
forked process: 96907
child process started successfully, parent exiting
mongo3：

[root@localhost ~]# mongod --replSet sbc -f /etc/mongod.conf --fork
about to fork child process, waiting until server is ready for connections.
forked process: 96105
child process started successfully, parent exiting

配置集合
在mongo1端进行集合配置

config文件配置
进入mongo1的mongodb数据库服务，声明配置文件

        }
    ],
    "ok" : 1

可以看出mongo1为主节点，mongo2和mongo3为从节点，集群状态正常，搭建完成
