PHP7都出了，自然我是要安装的，上次写的那个编译开发环境并没有针对性的说PHP，就这次说清楚吧。

$ wget http://cn2.php.net/get/php-7.0.0.tar.gz/from/this/mirror
$ mv mirror php7.tar.gz

$ tar -zxvf php7.tar.gz
$ cd php7

$ sudo apt-get install libxml2-dev

$ sudo apt-get install libcurl4-openssl-dev

$ sudo apt-get install curl libmcrypt-dev

configure: error: png.h not found.

$ sudo apt-get install libpng12-dev

$ ./configure --enable-debug --with-mysql --with-gd --with-curl --prefix=/opt/php7 --enable-fpm --enable-cgi --with-openssl --enable-mbstring --with-mcrypt --with-pdo-mysql --with-mysql-sock=/var/run/mysqld/mysqld.sock
$ make -j 4
$ sudo make install

$ cd ~
$ vim .zshrc # 或者其他的.bashrc什么的

加入以下内容在最后一行:

$PATH=$PATH:/opt/php7/bin;

这个步骤比较长，得有点儿耐心

首先找个php.ini文件，然后放到/opt/php7/lib里面，然后

给两个文件改名

$ suo cp /opt/php7/etc/php-fpm.conf.default /opt/php7/etc/php-fpm.conf
$ suo cp /opt/php7/etc/php-fpm.d/www.conf.default /opt/php7/etc/php-fpm.d/www.conf

然后调整里面的东西

先给个pid取消注释

$ sudo vim /opt/php7/etc/php7-fpm.conf

[...]
pid = run/php-fpm.pid
[...]

改一下用户组和用户

$ sudo vim /opt/php7/etc/php7-fpm.d/www.conf

user = YourUsername
group = YourGroup

然后创建文件：

$ sudo vim /etc/init.d/php7-fpm

写入以下内容，注意一些文件名

#! /bin/sh

        *)
                echo "Usage: $0 {start|stop|force-quit|restart|reload}"
                exit 1
        ;;
esac

赋权：

$ sudo chmod 755 /etc/init.d/php7-fpm
$ sudo vim /lib/systemd/system/php7-fpm.service

然后写入下面的内容：

[Unit]
Description=The PHP 7 FastCGI Process Manager
After=network.target

[Service]
Type=simple
PIDFile=/opt/php7/var/run/php-fpm.pid
ExecStart=/opt/php7/sbin/php-fpm --nodaemonize --fpm-config /opt/php7/etc/php-fpm.conf
ExecReload=/bin/kill -USR2 $MAINPID

[Install]
WantedBy=multi-user.target

试试看行不行：

$ php -v
$ sudo /etc/init.d/php-fpm start

没有出错就对了，出错了请在下面留言，我看看怎么回事。

好了，到这里其实已经没有问题了。但是剩下的Nginx也得稍微调整一下

$ sudo vim /etc/nginx/site-available/default

改成这样

fastcgi_pass 127.0.0.1:9000

重启服务，走起！

$ sudo service nginx restart
$ sudo service php7-fpm restart

按照他们的指导做就行了

$ git clone https://github.com/swoole/swoole-src.git
$ cd swoole-src
$ phpize
$ ./configure
$ make && sudo make install

在php.ini里面写上扩展

$ sudo vim /opt/php7/lib/php.ini

随便找个地方，不过我还是建议放到extension那边，大概第900行左右

extension=swoole.so

试试看swoole有没有安装好

$ php -m | grep swoole

有输出就是没问题，没输出就是有问题。
