php添加扩展模块

 给PHP增加SNMP模块

cd /usr/local/src/
tar zxf php-5.3.10.tar.gz
cd php-5.3.10/ext/snmp
#运行phpize生成configure
/usr/local/php/bin/phpize
#编译,指定php-config
./configure --with-php-config=/usr/local/php/bin/php-config
编译错误缺少包
yum install net-snmp net-snmp-devel
#继续编译
./configure --with-php-config=/usr/local/php/bin/php-config
make;make install
#建立一个目录来存放扩展的模块
mkdir /usr/local/php/etc/ext
#复制snmp.so到模块目录
cp /usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/snmp.so /usr/local/php/etc/ext/
#编辑php.ini文件,指定PHP到哪个目录读模块
vi /usr/local/php/lib/php.ini
extension_dir="/usr/local/php/etc/ext"
#Load模块
extension=snmp.so
#保存退出
重启apache
/usr/local/apache/bin/apachectl graceful
再用/usr/local/php/bin/php -m|grep ftp查看是否有snmp.so
