Linux下配置nginx支持.cgi，linuxnginx支持.cgi
Linux下配置nginx支持.cgi，linuxnginx支持.cgi
Linux下配置nginx支持.cgi说明：
操作系统：CentOS 6.x
web环境：php+nginx+mysql
nginx安装目录：/usr/local/nginx
nginx配置文件：/usr/local/nginx/conf/nginx.conf
nginx默认站点目录：/usr/local/nginx/html/
需求：让nginx能够解析.cgi后缀的文件
具体操作：
一、安装perl-fcgi依赖包，通过安装perl-fcgi来支持nginx运行.cgi
yum install perl-CPAN perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker
二、安装perl
cd /usr/local/src
wget http://www.cpan.org/src/5.0/perl-5.20.0.tar.gz #下载安装包，需要提前安装wget工具
tar -zxzf perl-5.20.0.tar.gz #解压
cd perl-5.20.0 #进入目录
./Configure -des -D prefix=/usr/local/perl #配置
make #编译
make install #安装
mv /usr/bin/perl /usr/bin/perl.bak #备份系统默认的perl
ln -s /usr/local/perl/bin/perl /usr/bin/perl #把刚刚安装好的新perl软连接到perl在系统中的默认位置
三、安装perl支持模块
1、安装perl fcgi模块
cd /usr/local/src
wget http://www.cpan.org/authors/id/F/FL/FLORA/FCGI-0.74.tar.gz
tar zxvf FCGI-0.74.tar.gz
cd FCGI-0.74
perl Makefile.PL #配置
make
make install
2、安装FCGI-ProcManager模块
cd /usr/local/src
wget http://www.cpan.org/authors/id/B/BO/BOBTFISH/FCGI-ProcManager-0.24.tar.gz
tar zxvf FCGI-ProcManager-0.24.tar.gz
cd FCGI-ProcManager-0.24
perl Makefile.PL
make
make install
3、安装IO模块
cd /usr/local/src
wget http://www.cpan.org/authors/id/G/GB/GBARR/IO-1.25.tar.gz
tar zxvf IO-1.25.tar.gz
cd IO-1.25
perl Makefile.PL
make
make install
4、安装IO::ALL模块
cd /usr/local/src
wget http://www.cpan.org/authors/id/I/IN/INGY/IO-All-0.79.tar.gz
tar zxvf IO-All-0.79.tar.gz
cd IO-All-0.79
perl Makefile.PL
make
make install
四、配置nginx支持.cgi
1、vi /usr/local/nginx/perl-fcgi.pl #编辑，添加以下代码
(以下是perl_fcgi.pl文件，可以去网上下载，把它放到nginx目录下)
#!/usr/bin/perl

备注：以上代码在拷贝的时候注意格式，否则出错。
2、vi /usr/local/nginx/start_perl_cgi.sh #编辑，添加以下代码，注意，这里nginx运行账户为www组的www用户
（这是个脚本文件，可以自己写，它是为了启动perl_cgi程序）

################################################
:wq! #保存退出
chmod 755 /usr/local/nginx/start_perl_cgi.sh #添加脚本执行权限
/usr/local/nginx/start_perl_cgi.sh start #启动perl_cgi
cd /usr/local/nginx/logs #查看此目录下是否已生成perl-fcgi.sock文件
#如果没有生成此文件，请检查以上步骤，直到有这个文件，才能继续下面的操作。
3、添加perl_fcgi.conf文件
cd /usr/local/nginx/conf
vi perl_fcgi.conf #编辑，添加以下代码
location ~ .*\.(pl|cgi)?$
{
gzip off;
fastcgi_pass unix:/usr/local/nginx/logs/perl-fcgi.sock;
fastcgi_index index.cgi;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_read_timeout 60;
}
:wq! #保存退出
4、修改nginx配置文件/usr/local/nginx/conf/nginx.conf
cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf-bak #备份原文件
vi /usr/local/nginx/conf/nginx.conf #编辑修改，在server段添加include perlfcgi.conf;
fastcgi_pass unix:/usr/local/nginx/logs/perl-fcgi.sock; (注意目录路径)
以下内容是虚拟主机nagios.artron.net.conf的内容，（以为此文档是解决nagios下让nginx能够解析.cgi后缀的文件） server
{
listen 80;
server_name 192.168.63.30;
index index.html index.htm index.php;
root /data/nagios/share;
auth_basic "Nagios Access";
auth_basic_user_file /data/nagios/etc/htpasswd;
location ~ .*\.(cgi|pl)?$ {
root /data/nagios/sbin;
rewrite ^/nagios/cgi-bin/(.*)\.cgi /$1.cgi break;
fastcgi_pass unix:/data/nginx/logs/perl-fcgi.sock;
fastcgi_param SCRIPT_FILENAME /data/nagios/sbin$fastcgi_script_name;
fastcgi_index index.cgi;
include fastcgi.conf;
fastcgi_read_timeout 60;
fastcgi_param REMOTE_USER $remote_user;
}
include perl_fcgi.conf;
location /nagios {
alias /data/nagios/share;
}
location /cgi-bin/images {
alias /data/nagios/share/images;
}
location /cgi-bin/stylesheets {
alias /data/nagios/share/stylesheets;
}
location /cgi-bin {
alias /data/nagios/sbin;
}
location ~ .*\.php$
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fcgi.conf;
}
}
