php安装扩展的几种方法
注意
与Apache+PHP或者Nginx+PHP的运行模式不同,WorkerMan是基于PHP命令行 PHP CLI 运行的,使用的是不同的PHP可执行程序,使用的php.ini文件也可能不同。所以在网页中打印phpinfo()
看到安装了某个扩展,不代表命令行的PHP CLI也安装了对应的扩展。
如何确定PHP CLI安装了哪些扩展
运行 php -m
会列出命令行 PHP CLI 已经安装的扩展,结果类似如下:
~# php -m [PHP Modules] libevent posix pcntl ...
如何确定PHP CLI 的php.ini文件的位置
当我们安装扩展时,可能需要手动配置php.ini文件,把扩展加进去,所以要确认PHP CLI的php.ini文件的位置。可以运行php --ini
查找PHP CLI的ini文件位置,结果类似如下(各个系统显示结果会有差异):
~# php --ini Configuration File (php.ini) Path: /etc/php5/cli Loaded Configuration File: /etc/php5/cli/php.ini Scan for additional .ini files in: /etc/php5/cli/conf.d Additional .ini files parsed: /etc/php5/cli/conf.d/apc.ini, /etc/php5/cli/conf.d/libevent.ini, /etc/php5/cli/conf.d/memcached.ini, /etc/php5/cli/conf.d/MySQL.ini, /etc/php5/cli/conf.d/pdo.ini, /etc/php5/cli/conf.d/pdo_mysql.ini ...
给PHP CLI安装扩展(安装memcached扩展为例)
方法一、使用apt或者yum命令安装
如果PHP是通过 apt 或者 yum 命令安装的,则扩展也可以通过 apt 或者 yum 安装
debian/ubuntu等系统apt安装PHP扩展方法(非root用户需要加sudo命令)
1、利用apt-cache search
查找扩展包
~# apt-cache search memcached php php-apc - APC (Alternative PHP Cache) module for PHP 5 php5-memcached - memcached module for php5
2、使用apt-get install
安装扩展包
~# apt-get install -y php5-memcached Reading package lists... Done Reading state information... Done ...
centos等系统yum安装PHP扩展方法
1、利用yum search
查找扩展包
~# yum search memcached php php-pecl-memcached - memcached module for php5
2、使用yum install
安装扩展包
~# yum install -y php-pecl-memcached Reading package lists... Done Reading state information... Done ...
说明:
使用apt或者yum安装PHP扩展会自动配置php.ini文件,安装完直接可用,十分方便。缺点是有些扩展在apt或者yum中没有对应的扩展安装包。
方法二、使用pecl安装
使用pecl install
命令安装扩展
1、pecl install
安装
~# pecl install memcached downloading memcached-2.2.0.tgz ... Starting to download memcached-2.2.0.tgz (70,449 bytes) ....
方法三、使用phpzip安装模块
一、环境介绍
[root@ghzz ~]# cat /etc/redhat-release CentOS release 6.5 (Final) You have new mail in /var/spool/mail/root [root@ghzz ~]# php -v Zend Guard Loader requires Zend Engine API version 220121212. The Zend Engine API version 220131226 which is installed, is newer. Contact Zend Technologies at http://www.zend.com/ for a later version of Zend Guard Loader. PHP 5.6.14 (cli) (built: Jul 7 2016 12:43:11) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies
二、查找模块
方法一:去php安装路径下ext目录下都是模块
cd /root/software/php-5.6.14/ext/exif
如果找不到 find ./ -type d -name "php*" 去查找
###这个模块,应该是php安装包内自带的,但是./configure编译安装的时候没有加载的包
方法二:php官网
PHP官网地址:http://pecl.php.net/packages.php
三、编译安装 (加载模块)
1)进入php存储模块目录
[root@ghzz lsolesen-pel-56d1b7f]# cd /root/software/php-5.6.14/ext/exif ##测试环境 ##如果找不到 find ./ -type f -name "php-*" 去查找 [root@ghzz exif]# ll 总用量 196 -rw-r--r-- 1 1000 1000 333 9月 30 2015 config.m4 -rw-r--r-- 1 1000 1000 308 9月 30 2015 config.w32 -rw-r--r-- 1 1000 1000 36 9月 30 2015 CREDITS -rw-r--r-- 1 1000 1000 496 9月 30 2015 example.php -rw-r--r-- 1 1000 1000 145331 9月 30 2015 exif.c -rw-r--r-- 1 1000 1000 4933 9月 30 2015 exif.dsp -rw-r--r-- 1 1000 1000 1953 9月 30 2015 package.xml -rw-r--r-- 1 1000 1000 1463 9月 30 2015 php_exif.h -rw-r--r-- 1 1000 1000 29 9月 30 2015 test.php drwxr-xr-x 2 1000 1000 4096 9月 30 2015 tests -rw-r--r-- 1 1000 1000 11232 9月 30 2015 test.txt
2)使用phpize添加php动态模块
作用:使用phpize生成
[root@ghzz exif]# /usr/local/php/bin/phpize Configuring for: PHP Api Version: 20131106 Zend Module Api No: 20131226 Zend Extension Api No: 220131226 [root@ghzz exif]# ./configure -with-php-config=/usr/local/php/bin/php-config checking for grep that handles long lines and -e... /bin/grep #。。。省略若干字段 checking whether stripping libraries is possible... yes checking if libtool supports shared libraries... yes checking whether to build shared libraries... yes checking whether to build static libraries... no creating libtool appending configuration tag "CXX" to libtool configure: creating ./config.status config.status: creating config.h [root@ghzz exif]# make && make install /bin/sh /root/software/php-5.6.14/ext/exif/libtool --mode=compile cc -I. -I/root/software/php-5.6.14/ext/exif -DPHP_ATOM_INC -I/root/software/php-5.6.14/ext/exif/include -I/root/software/php-5.6.14/ext/exif/main -I/root/software/php-5.6.14/ext/exif -I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /root/software/php-5.6.14/ext/exif/exif.c -o exif.lo mkdir .libs cc -I. -I/root/software/php-5.6.14/ext/exif -DPHP_ATOM_INC -I/root/software/php-5.6.14/ext/exif/include -I/root/software/php-5.6.14/ext/exif/main -I/root/software/php-5.6.14/ext/exif -I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /root/software/php-5.6.14/ext/exif/exif.c -fPIC -DPIC -o .libs/exif.o /bin/sh /root/software/php-5.6.14/ext/exif/libtool --mode=link cc -DPHP_ATOM_INC -I/root/software/php-5.6.14/ext/exif/include -I/root/software/php-5.6.14/ext/exif/main -I/root/software/php-5.6.14/ext/exif -I/usr/local/php/include/php -I/usr/local/php/include/php/main -I/usr/local/php/include/php/TSRM -I/usr/local/php/include/php/Zend -I/usr/local/php/include/php/ext -I/usr/local/php/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -o exif.la -export-dynamic -avoid-version -prefer-pic -module -rpath /root/software/php-5.6.14/ext/exif/modules exif.lo cc -shared .libs/exif.o -Wl,-soname -Wl,exif.so -o .libs/exif.so creating exif.la (cd .libs && rm -f exif.la && ln -s ../exif.la exif.la) /bin/sh /root/software/php-5.6.14/ext/exif/libtool --mode=install cp ./exif.la /root/software/php-5.6.14/ext/exif/modules cp ./.libs/exif.so /root/software/php-5.6.14/ext/exif/modules/exif.so cp ./.libs/exif.lai /root/software/php-5.6.14/ext/exif/modules/exif.la PATH="$PATH:/sbin" ldconfig -n /root/software/php-5.6.14/ext/exif/modules ---------------------------------------------------------------------- Libraries have been installed in: /root/software/php-5.6.14/ext/exif/modules If you ever happen to want to link against installed libraries in a given directory, LIBDIR, you must either use libtool, and specify the full pathname of the library, or use the `-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the `LD_RUN_PATH' environment variable during linking - use the `-Wl,--rpath -Wl,LIBDIR' linker flag - have your system administrator add LIBDIR to `/etc/ld.so.conf' See any operating system documentation about shared libraries for more information, such as the ld(1) and ld.so(8) manual pages. ---------------------------------------------------------------------- Build complete. Don't forget to run 'make test'. Installing shared extensions: /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/ [root@ghzz exif]# vi /usr/local/php/etc/php.ini ##如果文件路径不存在,就去安装目录查找php.ini文件 查找:extension = 再最后一个extension= 后面添加上extension = “exif.so” [root@ghzz ext]# grep -n "exif.so" /usr/local/php/etc/php.ini 743:extension = "exif.so" [root@ghzz exif]# /etc/init.d/php-fpm restart ##重启加载php模块
四、此时可能出现模块加载报错
Gracefully shutting down php-fpm . done Starting php-fpm [06-Jan-2017 13:43:43] NOTICE: PHP message: PHP Warning: PHP Startup: Invalid library (maybe not a PHP library) ‘fileinfo.so’ in Unknown on line 0 重新执行上面的操作还是一直报这个错误
解决方法
到你的模块安装目录,我这里是:
cd /****/soft/lnmp1.2-full/src/php-5.6.14/ext/exif make clean
在重新执行上面的全部命令,安装就成功了
报错原因:
因为之前编译的库文件.so存在异常,所以没有将新的写入,有冲突,需要清空后重新编译,即可启动
五、检查模块运行情况及效果
[root@ghzz ext]# php -m|grep exif exif
