php 几个扩展(extension)的安装笔记

centos下安装php扩展时遇到的问题

1.imap

cd /root/php-5.6.27/ext/imap

/usr/local/php/bin/phpize

./configure --prefix=/usr/local/imap

错误1

configure: error: utf8_mime2text() has new signature, but U8T_CANONICAL is missing. This should not happen. Check config.log for additional information.

解决方法

yum install libc-client-devel -y

错误2

configure: error: Cannot find imap library (libc-client.a). Please check your c-client installation.

解决方法

ln -s /usr/lib64/libc-client.so /usr/lib/libc-client.so

错误3

configure: error: This c-client library is built with Kerberos support.Add --with-kerberos to your configure line. Check config.log for details.

解决方法

./configure --prefix=/usr/local/imap --with-kerberos

错误4

configure: error: This c-client library is built with SSL support.Add --with-imap-ssl to your configure line. Check config.log for details.

解决方法

./configure --prefix=/usr/local/imap --with-kerberos --with-imap-ssl

make && make install

2.opcache

复制代码

cd /root/php-5.6.27/ext/opcache

/usr/local/php/bin/phpize

./configure --prefix=/usr/local/opcache

make && make install

echo "extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/opcache.so" >> /etc/php.ini

service php-fpm restart

复制代码

错误1

Gracefully shutting down php-fpm . done

Starting php-fpm [15-Jan-2018 13:45:26] NOTICE: PHP message: PHP Warning: PHP Startup: Invalid library (appears to be a Zend Extension, try loading using zend_extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/opcache.so from php.ini) in Unknown on line 0

done

解决方法

把extension改成zend_extension

echo "zend_extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/opcache.so" >> /etc/php.ini

3.apcu

默认没有apcu的扩展包，需要额外下载

github地址

https://github.com/krakjoe/apcu

php 5.6版本，下载4.0.11版本的apcu

https://codeload.github.com/krakjoe/apcu/tar.gz/v4.0.11

然后是正常安装

4.gd

首先安装：jpegsrc，freetype，libpng

tar xf jpegsrc.v9.tar.gz

cd jpeg-9/

CFLAGS="-O3 -fPIC" ./configure --prefix=/usr/local/jpeg

make && make install

tar zxf freetype-2.7.1.tar.gz

cd freetype-2.7.1

./configure --prefix=/usr/local/freetype

make && make install

tar zxf libpng-1.6.29.tar.gz

cd libpng-1.6.29

CFLAGS="-O3 -fPIC" ./configure --prefix=/usr/local/libpng

make && make install

然后编译gd库

cd /root/php-5.6.27/ext/gd/

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config --with-jpeg-dir=/usr/local/jpeg --with-png-dir=/usr/local/libpng --with-freetype-dir=/usr/local/freetype

make && make install

复制最后显示的一行 /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/

在/etc/php.ini最后一行添加

echo "extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/gd.so" >> /etc/php.ini

5.ldap

php-ldap模块作用就是实现ldap认证，因此需要安装openldap openldap-devel

yum install openldap

yum install openldap-devel

拷贝库文件

cp -frp /usr/lib64/libldap* /usr/lib/

编译安装php-ldap模块

cd /usr/local/src/php-7.0.21/ext/ldap/

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make

make install

然后在php的php.ini的配置文件添加

echo "extension = /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/ldap.so" >> /etc/php.ini
