php7編譯安裝與php5共存

1.下載  

wget  http://php.net/get/php-7.0.5.tar.gz/from/a/mirror

2.解壓

tar zxvf php-7.0.5.tar.gz
cd php-7.0.5

3.安裝，因爲本來5.5安裝在 /usr/local/php 下面，因此新版的php7 我就安裝到 /usr/local/php7 了

./configure --prefix=/usr/local/php7 \
 --with-curl \
 --with-freetype-dir \
 --with-gd \
 --with-gettext \
 --with-iconv-dir \
 --with-kerberos \
 --with-libdir=lib64 \
 --with-libxml-dir \
 --with-mysqli \
 --with-openssl \
 --with-pcre-regex \
 --with-pdo-mysql \
 --with-pdo-sqlite \
 --with-pear \
 --with-png-dir \
 --with-xmlrpc \
 --with-xsl \
 --with-zlib \
 --enable-fpm \
 --enable-bcmath \
 --enable-libxml \
 --enable-inline-optimization \
 --enable-gd-native-ttf \
 --enable-mbregex \
 --enable-mbstring \
 --enable-opcache \
 --enable-pcntl \
 --enable-shmop \
 --enable-soap \
 --enable-sockets \
 --enable-sysvsem \
 --enable-xml \
 --enable-zip

4.配置

cp php.ini-production /usr/local/php7/etc/php.ini
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm7

php7中www.conf這個配置文件配置phpfpm的端口號，修改 usr/local/php7/etc/php-fpm.d/www.conf

5.出現錯誤

    xsl 相關錯誤
    現象：configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution
    解決辦法：yum install -y libxslt libxslt-devel libxml2 libxml2-devel
