PHP7

PHP7都出了，自然我是要安裝的，上次寫的那個編譯開發環境并沒有針對性的說PHP，就這次說清楚吧。

Download

$ 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

libxml

$ sudo apt-get install libxml2-dev

OpenSSL

$ sudo apt-get install libcurl4-openssl-dev

mcrypt

$ sudo apt-get install curl libmcrypt-dev

GD

configure: error: png.h not found.

$ sudo apt-get install libpng12-dev

configure

$ ./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

PATH

$ cd ~

$ vim .zshrc # 或者其他的.bashrc什么的

加入以下內容在最后一行:

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

php-fpm

這個步驟比較長，得有點兒耐心

首先找個php.ini文件，然后放到/opt/php7/lib里面，然后

給兩個文件改名

$ 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

然后調整里面的東西

先給個pid取消注釋

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

[...]

pid = run/php-fpm.pid

[...]

改一下用戶組和用戶

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

user = YourUsername

group = YourGroup

然后創建文件：

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

寫入以下內容，注意一些文件名

#! /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

賦權：

$ sudo chmod 755 /etc/init.d/php7-fpm

$ sudo vim /lib/systemd/system/php7-fpm.service

然后寫入下面的內容：

[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

試試fpm

試試看行不行：

$ php -v

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

沒有出錯就對了，出錯了請在下面留言，我看看怎么回事。

好了，到這里其實已經沒有問題了。但是剩下的Nginx也得稍微調整一下

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

改成這樣

fastcgi_pass 127.0.0.1:9000

重啟服務，走起！

$ sudo service nginx restart

$ sudo service php7-fpm restart

Swoole

$ git clone https://github.com/swoole/swoole-src.git

$ cd swoole-src

$ phpize

$ ./configure

$ make && sudo make install

在php.ini里面寫上擴展

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

隨便找個地方，不過我還是建議放到extension那邊，大概第900行左右

extension=swoole.so

檢查一下

試試看swoole有沒有安裝好

$ php -m | grep swoole

有輸出就是沒問題，沒輸出就是有問題。
