CentOS 7上PHP默认是以apache或者nobody的身份运行的,这种方式下由于PHP运行需要的权限比较大,会有安全隐患,还可能会受到服务器其他用户影响。
通过phpinfo查看PHP信息如下:
apache运行php
可以看出来,PHP目前是作为Apache的一部分在运行,而不会为每个脚本运行一个独立进程。如果希望PHP脚本运行时是以当前用户的身份而不是Apache,可以通过部署suPHP来实现。接下来介绍如何在CentOS 7上安装suPHP。
先配置安装suphp所需的环境:
yum -y groupinstall 'Development Tools'
yum -y install apr-devel
yum -y install httpd-devel
下载suphp安装包:
mkdir temp
cd temp
wget http://suphp.org/download/suphp-0.7.2.tar.gz
tar zxvf suphp-0.7.2.tar.gz
下载并安装suphp补丁:
wget -O patchingsuphp.patch https://www.webhostinghero.com/downloads/php/suphp.patch
patch -Np1 -d suphp-0.7.2 < patchingsuphp.patch
cd suphp-0.7.2
autoreconf -if
运行./configure:
./configure --prefix=/usr/ --sysconfdir=/etc/ --with-apr=/usr
/bin/apr-1-config --with-apache-user=apache --with-setid-mode=owner
--with-logfile=/var/log/httpd/suphp_log
编译并安装:
make
make install
在Apache配置目录下创建suphp.conf
vi /etc/httpd/conf.d/suphp.conf
并写入:
LoadModule suphp_module modules/mod_suphp.so
/etc目录下创建suphp.conf配置文件:
vi /etc/suphp.conf
并写入配置文件内容如下:
[global]
;Path to logfile
logfile=/var/log/httpd/suphp.log
;Loglevel
loglevel=info
;User Apache is running as
webserver_user=apache
;Path all scripts have to be in
docroot=/
;Path to chroot() to before executing script
;chroot=/mychroot
; Security options
allow_file_group_writeable=true
allow_file_others_writeable=false
allow_directory_group_writeable=true
allow_directory_others_writeable=false
;Check wheter script is within DOCUMENT_ROOT
check_vhost_docroot=true
;Send minor error messages to browser
errors_to_browser=false
;PATH environment variable
env_path=/bin:/usr/bin
;Umask to set, specify in octal notation
umask=0077
; Minimum UID
min_uid=100
; Minimum GID
min_gid=100[handlers]
;Handler for php-scripts
x-httpd-suphp="php:/usr/bin/php-cgi"
;Handler for CGI-scripts
x-suphp-cgi="execute:!self"
如果希望domainname这个目录以用户user身份运行,那么修改目录所有者属性为user,如下:
chown -R [user].[user] /var/www/html/[domainname]
最后在Apache配置文件中找到相应域名,并开启suphp:
<FilesMatch ".+\.ph(p[345]?|t|tml)$">
SetHandler None
