PHP 安装扩展

• 安装libevent

#tar –zxvf libevent-1.4.12-stable.tar.gz

#cd libevent-1.4.12

#./configure--prefix=/usr/local/servers/libevent

#make&& make install

• 安装memcache

先安装libevent

#tar –zxvflibevent-1.4.12-stable.tar.gz

#cdlibevent-1.4.12-stable

#./configure--prefix=/usr/local/servers/libevent

#make

#makeinstall

然后安装memcached，同时需要安装中指定libevent的安装位置

#tar -zxvf memcached-1.2.6.tar.gz

#cd memcached-1.2.6

#./configure--prefix=/usr/local/servers/memcached--with-libevent=/usr/local/servers/libevent

#make

#make install
#usr/local/servers/memcached/bin/memcached -d -m 128 -l localhost -p 11211 -uroot （启动memcached）

然后安装memcache

#tar -zxvf memcache-3.0.8.tgz

#cd memcache-3.0.8

#/usr/local/php5/bin/phpize
#./configure -enable-memcache=/usr/local/servers/memcached--with-php-config=/usr/local/php5/bin/php-config

#make

#make install

#ll /usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/  

安装完成后也有类似memcache的提示
在/usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/ 路径下会出现memcached.so
编辑 php.ini添加如下
extension=/usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/memcache.so

extension=memcache.so

重启php-fpm查看php是否支持了memcached

• php-fpm的启动参数

复制代码代码如下:

测试php-fpm配置
#/usr/local/php5/sbin/php-fpm -t
#/usr/local/php5/sbin/php5-fpm -c /usr/local/php5/etc/php.ini -y /usr/local/php5/etc/php5-fpm.conf-t
（指定路径）
启动php-fpm
#/usr/local/php5/sbin/php-fpm

/usr/local/php5/sbin/php5-fpm -c /usr/local/php5/etc/php.ini -y /usr/local/php5/etc/php-fpm.conf

更改目录文件存放在

#vim /etc//rc.d/init.d/php-fpm

prefix=/usr/local/php5

• PHP5.0以上版本自带memcache扩展

先把之前的php.ini配置文件备份一下

#cp php.ini php.ini.bak

重新./configure

#./configure --prefix=/usr/local/php5--with-config-file-path=/usr/local/php5/etc --with-mysql=/usr/local/mysql--with-mysql-sock=/tmp/mysql.sock --with-gd --with-iconv --with-zlib--enable-xml --enable-magic-quotes --enable-safe-mode --enable-bcmath --enable-shmop--enable-sysvsem --enable-inline-optimization --with-curlwrappers--enable-mbregex --enable-fpm --enable-mbstring --enable-ftp--enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets--with-xmlrpc --enable-zip --enable-soap --with-pear --with-gettext--enable-session --with-mcrypt --with-curl --enable-pod --with-pdo-mysql--with-pdo-mysql=mysqlnd --without-pod-sqlite

这时会报错：

make: ***[sapi/cli/PHP] Error 1

解决;

Vim Makefile

在EXTRA_LIBS = -lcrypt-lcrypt -lrt -lmysqlclient_r -lgd -lfreetype -lpng -lz -ljpeg -lz -lresolv -lm -ldl-lnsl -lxml2 -lz -lm -lxml2-lz -lm -lmysqlclient_r -lz -lcrypt -lnsl -lm -lxml2-lz -lm -lxml2 -lz -lm -lcrypt -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm–lcrypt

在最后加上-liconv

#make

#make install

#cd /usr/local/php5/bin

#./pecl install memcache

重新启动nginx php-fpm

进去phpinfo进去查看

• 或者用（用php自带扩展安装）

#/usr/local/php5/bin/php –m

出现如下扩展

# /usr/local/php5/bin/php -m

• 安装PDO_mysql

#tar –zxvfPDO_MYSQL-1.0.2.tgz

#cdPDO_MYSQL-1.0.2

#/usr/local/php5/bin/phpize

#./configure--with-php-config=/usr/local/php5/bin/php-config-with-pdo-mysql=/usr/local/mysql/

在make之前还要做一个mysql的header文件的软连接。因为mysql安装的时候指定了目录，不做软连接的话，还是找不到header文件

#ln -s/usr/local/mysql/include/* /usr/local/include/

#make

#makeinstall

#ll/usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/

会有一个pdo_mysql.so

#vim/etc/php.ini

添加

extension=/usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/pdo_mysql.so

extension=pdo_mysql.so

可以通过

#/usr/local/php5/bin/php -m

• Php增加mysqli扩展

php安装包里就自带，找到你php运行的版本，我是php-5.5.12，具体方法如下：

#cd /php-5.5.12/ext

注（/ext）里面有如下扩展：
