php安裝步驟：
1. 下載php-7.0.14.tar.gz简软，并將其解壓：
$ tar -zvxf php-7.0.14.tar.gz
2. 安裝相關(guān)依賴包：
$ apt-get install -y libxml2 libxml2-dev openssl libcurl4-gnutls-dev libjpeg-dev libpng12-dev libfreetype6-dev
3. 執(zhí)行：ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib
注：否則會報(bào)錯：configure: error: Cannot find OpenSSL's libraries
4. 編譯：
$ cd php-7.0.14
$ ./configure --with-openssl --with-mysqli=shared,mysqlnd --with-pdo-MySQL=shared,mysqlnd \
--with-gd --with-iconv --with-zlib --enable-zip \
--enable-inline-optimization --disable-debug --disable-rpath --enable-shared --enable-xml \
--enable-bcmath --enable-shmop --enable-sysvsem --enable-mbregex --enable-mbstring \
--enable-gd-native-ttf --enable-pcntl --enable-sockets --with-xmlrpc --enable-soap \
--without-pear --with-gettext --enable-session --with-curl --with-jpeg-dir --with-freetype-dir --enable-opcache --enable-fpm \
--enable-fastcgi --without-gdbm --disable-fileinfo
5. 安裝：
$ make && make install
成功：
php-fpm配置
$ cd php-7.0.14
$ cp php.ini-production /usr/local/etc/php.ini
在php.ini中添加一行：cgi.fix_pathinfo=0$ cp /usr/local/etc/php-fpm.conf.default /usr/local/etc/php-fpm.conf
$ cp /usr/local/etc/php-fpm.d/www.conf.default /usr/local/etc/php-fpm.d/www.conf$ vi /usr/local/etc/php-fpm.d/www.conf
將group = nobody修改為 group = ,即將nobody刪除。否則在后面執(zhí)行service php-fpm start時會報(bào)錯望忆，即Starting php-fpm [10-Feb-2017 06:32:10] ERROR: [pool www] cannot get gid for group 'nobody'
（可直接執(zhí)行：sed -i "s/group = nobody/group = /g" /usr/local/etc/php-fpm.d/www.conf）$ vi /usr/local/etc/php-fpm.conf
將php-fpm.conf最后一行的include=NONE/etc/php-fpm.d/.conf修改為include=etc/php-fpm.d/.conf
（注：此時可以使用命令進(jìn)行測試：
$ /usr/local/sbin/php-fpm -t
輸出：NOTICE: configuration file /usr/local/etc/php-fpm.conf test is successful 即配置正確）$ cp /root/php-7.0.14/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
$ chmod 755 /etc/init.d/php-fpm
$ service php-fpm start
輸出：Starting php-fpm done
測試是否能解析php文件：
注：先要安裝nginx，具體步聚見http://www.reibang.com/p/6b70db035b95
- 在/usr/local/nginx/html/文件夾下創(chuàng)建一個用于測試的php文件，如test.php:
<?php
phpinfo()
?>
- 啟動nginx（需要對腳本做修改），在瀏覽器中輸入
http://localhost/test.php称龙，看到以下頁面即成功。
