添加的库文件路径一定要和系统平台arch一致，32bit的系统直接添加【/usr/local/lib】即可，64bit系统要填加【/usr/local/lib64.】否则依旧会报错，本文将详细介绍centos7下如何安装PHP7。

一、官网安装方法：

二、编译安装

1.下载php7

wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.20.tar.gz/from/this/mirror

或者直接网页下载

http://php.net/get/php-7.1.20.tar.gz/from/a/mirror

2.解压php7

tar -xvf php7.tar.gz

3.进入php目录

cd /usr/local/src/php-7.1.20

4.安装依赖包

yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

5.编译配置（如果出现错误，基本都是上一步的依赖文件没有安装所致）

./configure \--prefix=/software/php \--with-config-file-path=/etc \--enable-fpm \--with-fpm-user=www \--with-fpm-group=www \--enable-inline-optimization \--disable-debug \--disable-rpath \--enable-shared \--enable-soap \--with-libxml-dir \--with-xmlrpc \--with-openssl \--with-mcrypt \--with-mhash \--with-pcre-regex \--with-sqlite3 \--with-zlib \--enable-bcmath \--with-iconv \--with-bz2 \--enable-calendar \--with-curl \--with-cdb \--enable-dom \--enable-exif \--enable-fileinfo \--enable-filter \--with-pcre-dir \--enable-ftp \--with-gd \--with-openssl-dir \--with-jpeg-dir \--with-png-dir \--with-zlib-dir \--with-freetype-dir \--enable-gd-native-ttf \--enable-gd-jis-conv \--with-gettext \--with-gmp \--with-mhash \--enable-json \--enable-mbstring \--enable-mbregex \--enable-mbregex-backtrack \--with-libmbfl \--with-onig \--enable-pdo \--with-mysqli=mysqlnd \--with-pdo-mysql=mysqlnd \--with-zlib-dir \--with-pdo-sqlite \--with-readline \--enable-session \--enable-shmop \--enable-simplexml \--enable-sockets \--enable-sysvmsg \--enable-sysvsem \--enable-sysvshm \--enable-wddx \--with-libxml-dir \--with-xsl \--enable-zip \--enable-mysqlnd-compression-support \--with-pear \--enable-opcache

报错解决

最实用的解决办法如下:

问题：

1:  wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/libmcrypt-2.5.7.tar.gz

2:  tar zxf libmcrypt-2.5.7.tar.gz

3:  ./configure --prefix=/usr/local

4:  make && make install

问题：configure: error: Don't know how to define struct flock on this system, set –enable-opcache=no

解决：解决办法：

vim /etc/ld.so.conf.d/local.conf

# 编辑库文件

/usr/local/lib

# 添加该行

ldconfig -v

# 使之生效

注意事项：

这里添加的库文件路径一定要和你系统平台arch一致，32bit的系统直接添加/usr/local/lib即可，64bit系统要填加/usr/local/lib64.否则依旧会报错，我当时就是添加了/usr/local/lib死活编辑不了，后来更改为/usr/local/lib64才可以。

6.正式安装

make && make install

7.配置环境变量

vi /etc/profilePATH=$PATH:/usr/local/php/binexport PATHsource /etc/profile

8.配置php-fpm

cp php.ini-production /usr/local/php/etc/php.inicp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confcp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.confcp sapi/fpm/init.d.php-fpm /usr/local/php/etc/php-fpmchmod +x /usr/local/php/etc/php-fpmln /usr/local/php/etc/php.ini /etc/php.ini

9、创建www用户

useradd www

10、配置启动项参数

vim /usr/local/php/etc/php-fpm.d/www.confpm.max_children = 500pm.start_servers = 105pm.min_spare_servers = 10pm.max_spare_servers = 200

11.启动php-fpm

/usr/local/php/etc/php-fpm start设置 php-fpm开机启动cp /usr/local/src/php-5.5.14/sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm #拷贝php-fpm到启动目录chmod +x /etc/rc.d/init.d/php-fpm #添加执行权限chkconfig php-fpm on #设置开机启动service php-fpm startpkill php-fpm 强制关闭
