编译安装php-fpm
之前的服务器一直使用的lnmp自动化安装脚本来安装nginx, php-fpm等服务器环境，lnmp脚本有个缺点就是你可以一次性安装nginx, php-fpm, MySQL，但是你不能去分别安装这些服务，而且nginx貌似还不能自己加模块的样子。所以，喜欢瞎折腾的我边学边试了一把自己编译安装这些环境，记录一下，以便备忘。
因为从网上看到php7的执行效率比php5高了一倍的消息，所以给我的网站马上换上了php7，在这里编译安装的是php7.1.3
wget http://cn2.php.net/get/php-7.1.3.tar.bz2/from/this/mirrortar xvf mirror && cd php-7.1.3
apt-get install libkrb5-dev \libc-client2007e \libc-client2007e-dev \libcurl4-openssl-dev \libbz2-dev \libjpeg-dev \libmcrypt-dev \libxslt1-dev \libxslt1.1 \libpq-dev \libpng12-dev \libfreetype6-dev \build-essential \git \libopenssl-dev
ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib
./configure \--prefix=/usr/local/php \--with-config-file-path=/usr/local/php/etc \--with-zlib-dir \--with-freetype-dir \--enable-mbstring \--with-libxml-dir=/usr \--enable-soap \--enable-calendar \--with-curl \--with-mcrypt \--with-zlib \--with-gd \--disable-rpath \--enable-inline-optimization \--with-bz2 \--with-zlib \--enable-sockets \--enable-sysvsem \--enable-sysvshm \--enable-pcntl \--enable-mbregex \--enable-exif \--enable-bcmath \--with-mhash \--enable-zip \--with-pcre-regex \--with-pdo-mysql \--with-mysqli \--with-mysql-sock=/var/run/mysqld/mysqld.sock \--with-jpeg-dir=/usr \--with-png-dir=/usr \--enable-gd-native-ttf \--with-openssl \--with-fpm-user=www-data \--with-fpm-group=www-data \--enable-ftp \--with-imap \--with-imap-ssl \--with-kerberos \--with-gettext \--with-xmlrpc \--with-xsl \--enable-opcache \--enable-fpm
跟编译安装Nginx一样，如果它提示缺少什么模块的话，那就可以使用如下命令解决
apt-get install lib缺少的模块名-dev # 例如libssl-dev
make && make install
ln -sf /usr/local/php/sbin/php-fpm /usr/bin/php
创建软连接之后我们就可以在shell里使用php命令来直接执行了
在这里直接将默认的配置文件拷贝了一下
mv /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.confmv /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.confcp ./php.ini-production /usr/local/php/etc/php.ini
添加服务之后，我们就可以使用service命令来方便管理了：
vi /etc/init.d/php-fpm
添加如下代码：
