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

一、官網(wǎng)安裝方法：

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

相關(guān)學(xué)習(xí)推薦：PHP 編程從入門到精通

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(wǎng)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(jìn)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(xiàn)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

–enable-opcache

報錯解決

最實(shí)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(xiàng)：

這里添加的庫文件路徑一定要和你系統(tǒng)平臺arch一致，32bit的系統(tǒng)直接添加/usr/local/lib即可，64bit系統(tǒng)要填加/usr/local/lib64.否則依舊會報錯，我當(dāng)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(huán)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(chuàng)建www用戶

useradd www

10、配置啟動項(xiàng)參數(shù)

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(shè)置 php-fpm開機(jī)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(zhí)行權(quán)限

chkconfig php-fpm on #設(shè)置開機(jī)啟動

service php-fpm start

pkill php-fpm 強(qiáng)制關(guān)閉
