添加的庫文件路徑一定要和系統平臺arch一致，32bit的系統直接添加【/usr/local/lib】即可，64bit系統要填加【/usr/local/lib64.】否則依舊會報錯，本文將詳細介紹centos7下如何安裝PHP7。

一、官網安裝方法：

http://php.net/manual/zh/install.unix.nginx.php

二、編譯安裝

1.下載php7

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

或者直接網頁下載

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

2.解壓php7

tar -xvf php7.tar.gz

3.進入php目錄

cd /usr/local/src/php-7.1.20

4.安裝依賴包

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.編譯配置（如果出現錯誤，基本都是上一步的依賴文件沒有安裝所致）

./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

–with-libmbfl

–with-onig

–with-mysqli=mysqlnd

–with-zlib-dir

–with-pdo-sqlite

–with-readline

–enable-session

–enable-shmop

–enable-simplexml

–enable-sysvmsg

–enable-sysvsem

–enable-wddx

–with-libxml-dir

–with-xsl

–with-pear

–enable-opcache

報錯解決

最實用的解決辦法如下:

問題：

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

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

解決：解決辦法：

vim /etc/ld.so.conf.d/local.conf # 編輯庫文件

/usr/local/lib # 添加該行

ldconfig -v # 使之生效

注意事項：

這里添加的庫文件路徑一定要和你系統平臺arch一致，32bit的系統直接添加/usr/local/lib即可，64bit系統要填加/usr/local/lib64.否則依舊會報錯，我當時就是添加了/usr/local/lib死活編輯不了，后來更改為/usr/local/lib64才可以。

6.正式安裝

make && make install

7.配置環境變量

vi /etc/profile

PATH=$PATH:/usr/local/php/bin

export PATH

source /etc/profile

8.配置php-fpm

cp php.ini-production /usr/local/php/etc/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 sapi/fpm/init.d.php-fpm /usr/local/php/etc/php-fpm

chmod +x /usr/local/php/etc/php-fpm

ln /usr/local/php/etc/php.ini /etc/php.ini

9、創建www用戶

useradd www

10、配置啟動項參數

vim /usr/local/php/etc/php-fpm.d/www.conf

pm.max_children = 500

pm.start_servers = 105

pm.min_spare_servers = 10

pm.max_spare_servers = 200

11.啟動php-fpm

/usr/local/php/etc/php-fpm start

設置 php-fpm開機啟動

cp /usr/local/src/php-5.5.14/sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm #拷貝php-fpm到啟動目錄

chmod +x /etc/rc.d/init.d/php-fpm #添加執行權限

chkconfig php-fpm on #設置開機啟動

service php-fpm start

pkill php-fpm 強制關閉
