更新和安装依赖项
apt-get update
apt-get install -y bison autoconf build-essential pkg-config git-core libltdl-dev libbz2-dev libxml2-dev libxslt1-dev libssl-dev libicu-dev libpspell-dev libenchant-dev libmcrypt-dev libpng-dev libjpeg8-dev libfreetype6-dev libmysqlclient-dev libreadline-dev libcurl4-openssl-dev
删除任何现有的 php7 并重新创建 php7 和其他子目录
rm -rf /etc/php7
mkdir -p /etc/php7
mkdir -p /etc/php7/cli
mkdir -p /etc/php7/etc
删除当前工作目录中的所有 php-src 文件夹并从 git 分支重新安装
rm -rf php-src
git clone https://github.com/php/php-src.git --depth=1
将目录更改为 ext 以从 git 下载 pthread
cd php-src/ext
git clone https://github.com/krakjoe/pthreads -b master pthreads
返回 php-src 作为当前工作目录
cd ..
构建 php-src
./buildconf --force
设置配置选项，启用 zts、fpm 和其他适用于您自己情况的扩展
CONFIGURE_STRING="--prefix=/etc/php7 --with-bz2 --with-zlib --enable-zip --disable-cgi \
--enable-soap --enable-intl --with-mcrypt --with-openssl --with-readline --with-curl \
--enable-ftp --enable-mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd \
--enable-sockets --enable-pcntl --with-pspell --with-enchant --with-gettext \
--with-gd --enable-exif --with-jpeg-dir --with-png-dir --with-freetype-dir --with-xsl \
--enable-bcmath --enable-mbstring --enable-calendar --enable-simplexml --enable-json \
--enable-hash --enable-session --enable-xml --enable-wddx --enable-opcache \
--with-pcre-regex --with-config-file-path=/etc/php7/cli \
--with-config-file-scan-dir=/etc/php7/etc --enable-cli --enable-maintainer-zts \
--with-tsrm-pthreads --enable-debug --enable-fpm \
--with-fpm-user=www-data --with-fpm-group=www-data"
运行配置脚本并安装
./configure $CONFIGURE_STRING
make && make install
使以下帮助程序可执行
chmod o+x /etc/php7/bin/phpize
chmod o+x /etc/php7/bin/php-config
现在将目录更改为 pthreads 并运行 phpize
cd ext/pthreads*
/etc/php7/bin/phpize
设置pthreads的配置选项，但确保enable-pthreads=shared，这是配置的主要方面
./configure --prefix='/etc/php7' --with-libdir='/lib/x86_64-linux-gnu' \
--enable-pthreads=shared --with-php-config='/etc/php7/bin/php-config'
make && make install
FPM 安装涉及将配置文件复制到适当的位置并在必要时进行更改。
#back to current working directory php-src
cd ../../
#php.ini to be used by fpm-fcgi
cp -r php.ini-production /etc/php7/cli/php.ini
sed -i 's/;date.timezone =.*/date.timezone = Africa\/Lagos/' /etc/php7/cli/php.ini
cp /etc/php7/etc/php-fpm.conf.default /etc/php7/etc/php-fpm.conf
cp /etc/php7/etc/php-fpm.d/www.conf.default /etc/php7/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php7-fpm
sed -i 's/Provides: php-fpm/Provides: php7-fpm/' /etc/init.d/php7-fpm
sed -i 's#^php_fpm_BIN=.*#php_fpm_BIN=/usr/sbin/php7-fpm#' /etc/init.d/php7-fpm
sed -i 's#^php_fpm_CONF=.*#php_fpm_CONF=/etc/php7/etc/php-fpm.conf#' /etc/init.d/php7-fpm
sed -i 's#^php_fpm_PID=.*#php_fpm_PID=/var/run/php7-fpm.pid#' /etc/init.d/php7-fpm
将 pthreads.so 添加到 php-cli.ini，这将由命令行界面 (CLI) 使用
cp php.ini-production /etc/php7/cli/php-cli.ini
echo "extension=pthreads.so" > /etc/php7/cli/php-cli.ini
添加其他扩展和链接二进制文件
echo "zend_extension=opcache.so" >> /etc/php7/cli/php.ini
ln --symbolic /etc/php7/bin/php /usr/bin/php
ln --symbolic /etc/php7/sbin/php-fpm /usr/sbin/php7-fpm
chmod +x /etc/init.d/php7-fpm
update-rc.d php7-fpm defaults
service php7-fpm start
确保以下内容与 /etc/php7/etc/php-fpm.conf 中的内容相同
pid = /var/run/php7-fpm.pid
error_log = /var/log/php7-fpm.log
include=/etc/php7/etc/php-fpm.d/*.conf
确保以下内容与 /etc/php7/etc/php-fpm.d/www.conf 中的内容相同
user = www-data
group = www-data
listen = /var/run/php7-fpm.sock
listen.owner = www-data
listen.group = www-data
listen.mode = 0660
listen.allowed_clients = 127.0.0.1
security.limit_extensions = .php .php3 .php4 .php5 .php7
确保以下内容与 /etc/php7/cli/php.ini 中的内容相同
cgi.fix_pathinfo=1
要与 Nginx 一起使用，请在 nginx/sites-available/default 中执行以下操作
upstream php7-fpm {
server unix:/var/run/php7-fpm.sock;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
root /usr/share/nginx/html;
# Add index.php to the list if you are using PHP
index index.html index.htm;
server_name localhost;
location / {
try_files $uri $uri/ =404;
}
location ~ [^/]\.php(/|$) {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass php7-fpm;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
service nginx restart
要使用 pthreads，请记住它是通过命令行界面运行的。假设 thread.php 是您的并行编程代码，您无法通过使用浏览器执行 localhost/path/to/thread.php 以 sapi/fpm 模式运行它
<?php
//thread.php
class Part extends Threaded{ public function run(){} }
$parts = new Part();
for($i=0;$i<4;$i++) $parts[] = $i;
?>
相反，您可以通过“system”等命令行方法创建一个文件来执行代码 thread.php
<?php
system("php /path/to/thread.php");
?>
