运维日常：Linux调用双版本PHP

Posted 2021-01-03

1.当前系统状态

[[email protected] ~]# php -v
PHP 5.6.31 (cli) (built: Nov 24 2017 12:37:03)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend Guard Loader v3.3, Copyright (c) 1998-2014, by Zend Technologies
[[email protected] ~]# uname -r
3.10.0-693.5.2.el7.x86_64

2.下载解压软件包

wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2
tar -xf php-7.1.6.tar.bz2
cd php-7.1.6

3.安装环境包，保证服务器的gcc和g++环境
yum -y install libxml2 libxml2-devel openssl openssl-devel curl curl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel pcre pcre-devel libxslt libxslt-devel bzip2 bzip2-devel

4.预编译，检查环境
./configure --prefix=/usr/local/php7 --with-curl --with-freetype-dir --with-gd --with-gettext --with-iconv-dir --with-kerberos --with-libdir=lib64 --with-libxml-dir --with-mysqli --with-openssl --with-pcre-regex --with-pdo-mysql --with-pdo-sqlite --with-pear --with-png-dir --with-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-gd-native-ttf --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip

5.编译安装

ln -s /usr/local/lib/libiconv.so.2 /usr/lib64/
make ZEND_EXTRA_LIBS=‘-liconv‘
make install

6.配置相关php文件（/usr/local/php7是安装目录，区别原来的PHP版本）

cp php.ini-development /usr/local/php7/lib/php.ini
cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
cp sapi/fpm/php-fpm /usr/local/bin/php7-fpm

7.设置php.ini文件

vim /usr/local/php7/lib/php.ini
cgi.fix_pathinfo=0

打开php配置文件找到cgi.fix_pathinfo配置项，这一项默认被注释并且值为1，根据官方文档的说明，这里为了当文件不存在时，阻止nginx将请求发送到后端的PHP-FPM模块，从而避免恶意脚本注入的×××，所以此项应该去掉注释并设置为0

8.查看启动进程管理用户

cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

vim /usr/local/php7/etc/php-fpm.d/www.conf
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user‘s group
;       will be used.
user = nobody
group = nobody

9.启动php-fpm服务

/usr/local/bin/php7-fpm
[[email protected] ~]# netstat -tunlp |grep 9000
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      23384/php-fpm: mast

10.设置nginx调用PHP7

vim /usr/local/nginx/conf/vhost/linuxview.conf
location ~ .php$ {
   #不能有下面这句 try_files ,不然报错500
   # try_files $uri /index.php =404;
   # fastcgi_split_path_info ^(.+.php)(/.+)$;
   # root      html;
   #这句注意 后面是127.0.0.1,不然调用不了
   fastcgi_pass  127.0.0.1:9000;
   #fastcgi_pass  unix:/tmp/php-cgi.sock;
   fastcgi_index index.php;
   include fastcgi_params;
   fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;   
}

11.重加载nginx服务

nginx -s reload

nginx：这个便捷命令是/usr/local/nginx/sbin/nginx 的别名，
命令如下：建议写入环境变量文件。
alias nginx=/usr/local/nginx/sbin/nginx
