建议安装之前先看看安装帮助文件INSTALL

解压安装

# tar zxvf php-7.0.0RC1.tar.gz
# cd php-7.0.0RC1

首先查看安装帮助

# ./configure   --help
 ./configure --prefix=/usr/local/php \

 --with-recode=/usr \
 --with-ldap \
 --with-pear \
 --with-fpm-user=nobody \
 --with-fpm-group=nobody \
 --with-apxs2=/usr/sbin/apxs  # 如果需要apache支持，请设置此项，apxs2或apxs通常在apache的bin目录下

如果配置错误，需要安装需要的模块，直接yum一并安装依赖库

# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel pcre-devel gmp gmp-devel openssl \
openssl-devel curl curl-devel readline readline-devel libXpm-devel openldap openldap-devel\
recode recode-devel

注意：安装php7beta3的时候有几处配置不过去，需要yum一下，现在php-7.0.0RC1已经不用这样了。

# yum -y install curl-devel
# yum -y install libxslt-devel

编译安装

# make &&  make install

配置文件

# cp php.ini-development /usr/local/php/lib/php.ini
# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
# cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm

需要注意的是 php7中www.conf这个配置文件配置phpfpm的端口号等信息，如果你修改默认的9000端口号需在这里改，再改nginx的配置

启动

#  /etc/init.d/php-fpm

连接mysql

连接mysql提示 Warning: mysqli::real_connect(): (HY000/2002): No such file or directory
检查phpinfo输出信息中

mysql.default_socket
mysqli.default_socket
pdo_mysql.default_socket

三者的值
命令模式下启动mysql,输入status命令
查看UNIX socket的值是否一致
不一致则修改php.ini,重启nginx或者apache则可.

ps -ef|grep php-fpm
kill -9 324

问题总结

1. 提示 configure: error: Cannot find ldap libraries in /usr/lib cp -frp /usr/lib64/libldap* /usr/lib/
