编译安装PHP
1.下载php7
cd /usr/local/src/
wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.1.tar.gz/from/this/mirror
2.解压PHP7
tar -xvf php7.tar.gz
3.进入PHP源文件目录
cd php-7.0.4
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
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc/--enable-fpm --with-fpm-user=nginx --with-fpm-group=nginx --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 --with-apxs2=/usr/local/apache/bin/apxs
注意：--with-apxs2=/usr/local/apache/bin/apxs 一定要否则apache识别不到PHP
6.编译安装
make && make install
7.配置环境变量
vi /etc/profile
在末尾追加
PATH=$PATH:/usr/local/php/bin
export PATH
执行命令立即生效
source /etc/profile
修改Apache配置（让Apache可以编译PHP文件）
在配置文件httpd.conf追加以下代码
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
定位到DirectoryIndex 添加index.php
重启Apache
注意：启动报
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
#vim /web/apache/conf/httpd.conf (在这里/web/apahce是我安装apache的目录，你默认安装的话应该是/usr/local/apache2/icons)
找到#ServerName www.example.com:80 把#去掉，再重启apache即可没事了。
现象：
bogon:~/webserver/httpd-2.0.59 # /usr/local/apache2/bin/apachectl start
httpd: Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
httpd (pid 20183) already running
這個問題應該是沒有在 /etc/httpd/conf/httpd.conf 中設定 ServerName
vi /usr/local/apache2/conf/httpd.conf
最简单的，修改httpd.conf文件，增加:
ServerName www.example.com:80
我的改为:
ServerName localhost:80
再次启动就正常了!
