PHP7
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。
Download
{% highlight console %} $ wget http://cn2.php.net/get/php-7.0.0.tar.gz/from/this/mirror $ mv mirror php7.tar.gz {% endhighlight %}
{% highlight console %} $ tar -zxvf php7.tar.gz $ cd php7 {% endhighlight %}
libxml
{% highlight console %} $ sudo apt-get install libxml2-dev {% endhighlight %}
OpenSSL
{% highlight console %} $ sudo apt-get install libcurl4-openssl-dev {% endhighlight %}
mcrypt
{% highlight console %} $ sudo apt-get install curl libmcrypt-dev {% endhighlight %}
GD
configure: error: png.h not found.
{% highlight console %} $ sudo apt-get install libpng12-dev {% endhighlight %}
configure
{% highlight console %} $ ./configure --enable-debug --with-mysql --with-gd --with-curl --enable-zip --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 {% endhighlight %}
PATH
{% highlight console %} $ cd ~ $ vim .zshrc # 或者其他的.bashrc什么的 {% endhighlight %}
加入以下内容在最后一行:
{% highlight bash %} $PATH=$PATH:/opt/php7/bin; {% endhighlight %}
php-fpm
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
{% highlight console %} $ 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 {% endhighlight %}
然后调整里面的东西
先给个pid取消注释
{% highlight console %} $ sudo vim /opt/php7/etc/php7-fpm.conf {% endhighlight %}
{% highlight console %} [...] pid = run/php-fpm.pid [...] {% endhighlight %}
改一下用户组和用户
{% highlight console %} $ sudo vim /opt/php7/etc/php7-fpm.d/www.conf {% endhighlight %}
{% highlight console %} user = YourUsername group = YourGroup {% endhighlight %}
然后创建文件：
{% highlight console %} $ sudo vim /etc/init.d/php7-fpm {% endhighlight %}
写入以下内容，注意一些文件名
{% highlight bash %}
! /bin/sh
BEGIN INIT INFO
Provides: php7-fpm
Required-Start: $all
Required-Stop: $all
Default-Start: 2 3 4 5
Default-Stop: 0 1 6
Short-Description: starts php7-fpm
Description: starts the PHP FastCGI Process Manager daemon
END INIT INFO
php_fpm_BIN=/opt/php7/sbin/php-fpm
php_fpm_CONF=/opt/php7/etc/php-fpm.conf
php_fpm_PID=/opt/php7/var/run/php-fpm.pid
php_opts="--fpm-config $php_fpm_CONF"
wait_for_pid () {
try=0
while test $try -lt 35 ; do
case "$1" in
'created')
if [ -f "$2" ] ; then
try=''
break
fi
;;
'removed')
if [ ! -f "$2" ] ; then
try=''
break
fi
;;
esac
echo -n .
try=expr $try + 1
sleep 1
done
}
case "$1" in
start)
echo -n "Starting php-fpm "
$php_fpm_BIN $php_opts
if [ "$?" != 0 ] ; then
echo " failed"
exit 1
fi
wait_for_pid created $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
stop)
echo -n "Gracefully shutting down php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -QUIT cat $php_fpm_PID
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed. Use force-exit"
exit 1
else
echo " done"
echo " done"
fi
;;
force-quit)
echo -n "Terminating php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -TERM cat $php_fpm_PID
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
restart)
$0 stop
$0 start
;;
reload)
echo -n "Reload service php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -USR2 cat $php_fpm_PID
echo " done"
;;
*)
echo "Usage: $0 {start|stop|force-quit|restart|reload}"
exit 1
;;
esac
{% endhighlight %}
赋权：
{% highlight console %} $ sudo chmod 755 /etc/init.d/php7-fpm $ sudo vim /lib/systemd/system/php7-fpm.service {% endhighlight %}
然后写入下面的内容：
{% highlight console %} [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 {% endhighlight %}
Run
试试看行不行：
{% highlight console %} $ php -v $ sudo /etc/init.d/php-fpm start {% endhighlight %}
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
{% highlight console %} $ sudo vim /etc/nginx/site-available/default {% endhighlight %}
改成这样
{% highlight console %} fastcgi_pass 127.0.0.1:9000 {% endhighlight %}
重启服务，走起！
{% highlight console %} $ sudo service nginx restart $ sudo service php7-fpm restart {% endhighlight %}
Swoole
按照他们的指导做就行了
{% highlight console %} $ git clone https://github.com/swoole/swoole-src.git $ cd swoole-src $ phpize $ ./configure $ make && sudo make install {% endhighlight %}
在php.ini里面写上扩展
{% highlight console %} $ sudo vim /opt/php7/lib/php.ini {% endhighlight %}
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
{% highlight console %} extension=swoole.so {% endhighlight %}
checkout it
试试看swoole有没有安装好
{% highlight console %} $ php -m | grep swoole {% endhighlight %}
有输出就是没问题，没输出就是有问题。
