nginx 反向代理 与 Apache backend的配置联合配置

 

nginx 反向代理 与 Apache backend的配置联合配置:
说明: nginx 将http映射到Apache上的特定子目录。
配置方法步骤:
1.  设置域名, 子域名映射到指定服务器ip,
2. nginx设置好server ,以及对应的目录, 或者 转发到指定Apache端口。
server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;
 
        root /usr/share/nginx/html;
        index index.html index.htm;
 
        # Make site accessible from http://localhost/
        server_name localhost;
 
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
                # Uncomment to enable naxsi on this location
                # include /etc/nginx/naxsi.rules
        }
 
        # Only for nginx-naxsi used with nginx-naxsi-ui : process denied requests
        #location /RequestDenied {
        #       proxy_pass http://127.0.0.1:8080;
        #}
#error_page 404 /404.html;
 
        # redirect server error pages to the static page /50x.html
        #
        #error_page 500 502 503 504 /50x.html;
        #location = /50x.html {
        #       root /usr/share/nginx/html;
        #}
 
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #       fastcgi_split_path_info ^(.+\.php)(/.+)$;
        #       # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
        #
        #       # With php5-cgi alone:
        #       fastcgi_pass 127.0.0.1:9000;
        #       # With php5-fpm:
        #       fastcgi_pass unix:/var/run/php5-fpm.sock;
        #       fastcgi_index index.php;
 #       include fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #       deny all;
        #}
}

server{
        listen 80;
        server_name   nginx.xxxx.com;
        location / {
                root    /usr/share/nginx/html/www.xxxx.com;
                index   index.html;
        }
}

server{
        listen    80;
        server_name     www.xxxx.com apache.xxxx.com;
        index   index.html;
        location / {
                proxy_pass http://localhost:8080/www.xxxx.com/;
                proxy_redirect default;
        }
}
 
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#       listen 8000;
#       listen somename:8080;
#       server_name somename alias another.alias;
#       root html;
#       index index.html index.htm;
#
#       location / {
#               try_files $uri $uri/ =404;
#       }
#}
 
3. Apache 设置好ports.conf , 设置为2中相同(8080), 另外注意配置 sites_enable文件夹下的文件中的端口。
 
<VirtualHost *:8080>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        ServerName www.xxxx.com
 
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html
 
        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn
 
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
 
4. 启动nginx 加载新配置, 重启Apache
 4.1  启动nginx,只需nginx即可,若是修改配置后重新启动,则需要nginx -s reload.  关闭: nginx -s stop
 4.2  apache2ctl restart
 
5. 查看端口占用情况: netstat -anop | grep 80
 
6. Apache 的 mod_expires 与 mod_cache
Apache的过期策略可以通过apache的mod_expires和mod_headers两个模块设置:
 
1)模块mod_expires设置:
允许通过配置文件控制HTTP的"Expires"和"Cache-Control"头内容
mod_expires 模块的主要作用是自动生成页面头部信息中的 Expires 标签和 Cache-Control 标签,从而降低客户端的访问频率和次数,达到减少不必要流量和增加访问速度的目的
mod_expires 是 apache 众多模块中配置比较简单的一个,它一共只有三条指令
ExpiresActive 指令:打开或关闭产生”Expires:”和”Cache-Control:”头的功能。
ExpiresByType 指令:指定MIME类型的文档(例如:text/html)的过期时间。
ExpiresDefault 指令:默认所有文档的过期时间。
 
过期时间的写法
“access plus 1 month”
“access plus 4 weeks”
“now plus 30 days”
“modification plus 5 hours 3 minutes”
A2592000
M604800
access、now及A 三种写法的意义相同,指过期时间从访问时开始计算。
modification及M 的意义相同,指过期时间是以被访问文件的最后修改时间开始计算。
所以,后一种写法只对静态文件起作用,而由脚本生成的动态页面不受它的作用
 
配置实例:
 
    ExpiresActive On(开启mod_expires功能)
    ExpiresDefault "access plus 6 months"(默认的过期时间是6个月)
    ExpiresByType image/* "access plus 10 years"(图片的文件类型缓存时间为10年)
    ExpiresByType text/* "access plus 10 years"(文本类型缓存时间为10年)
    ExpiresByType application/* "access plus 30 minutes"(application文件类型缓存30分钟)
 
验证:image/jpeg 缓存时间为315360000s(10年)
 
 
如果将image/jpeg设置为不缓存(将max-age设置为0s):
 
#   ExpiresByType image/* "access plus 10 years"
ExpiresByType image/*  A0
 
2)模块mod_headers设置:
 
   # YEAR(flv,gif,ico文件类型的缓存时间为1年)
 
Header set Cache-Control “max-age=2592000″
 
 
# WEEK(pdf.swf,js,css缓存时间为一周)
 
Header set Cache-Control “max-age=604800″
 
 
# NEVER CACHE(jsp.swf,ico文件类型不缓存)
 
Header set Expires “Thu, 01 Dec 2003 16:00:00 GMT”
Header set Cache-Control “no-store, no-cache, must-revalidate”
Header set Pragma “no-cache”
