1. nginx模块

--add-module=../modules/ngx_devel_kit-0.2.18 
--add-module=../modules/set-misc-nginx-module-0.22rc8 
--add-module=../modules/srcache-nginx-module-0.22 
--add-module=../modules/redis-nginx-module-0.3.6 
--add-module=../modules/redis2-nginx-module-0.10

2. redis安装配置

# vim redis.conf
daemonize yes
pidfile /var/run/redis-6379.pid
port 6379
bind 127.0.0.1
timeout 0
tcp-keepalive 0
loglevel notice
logfile stdout
databases 16
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump.rdb
slave-serve-stale-data yes
slave-read-only yes
repl-disable-tcp-nodelay no
slave-priority 100
maxmemory 8096mb
maxmemory-policy volatile-ttl
appendonly no
appendfsync everysec
no-appendfsync-on-rewrite no
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
lua-time-limit 5000
slowlog-log-slower-than 10000
slowlog-max-len 128
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-entries 512
list-max-ziplist-value 64
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10
aof-rewrite-incremental-fsync yes

由于只把redis当做缓存使用,因此没有启用持久化。

3. nginx配置

# vim nginx.conf
http
{
    include    mime.types;
    default_type application/octet-stream;
 
    log_format main '$remote_addr - $remote_user [$time_local] "$request" '

                    '"$http_user_agent" "$http_x_forwarded_for" '
                    '"$gzip_ratio" $request_time $bytes_sent $request_length';
 
    log_format srcache_log '$remote_addr - $remote_user [$time_local] "$request" '

            srcache_fetch GET /redis $key;

        }
 
        include fastcgi_params;

     }
 
    location = /redis {

        set_md5 $redis_key $args;
        redis_pass redis;
    }
 
    location = /redis2 {

        set_unescape_uri $exptime $arg_exptime;
        set_unescape_uri $key $arg_key;

}

4. 测试
没有做缓存状态:

Nginx配置srcache_nginx模块搭配Redis建立缓存系统

有做缓存状态:

Nginx配置srcache_nginx模块搭配Redis建立缓存系统

5. 响应头状态
第一次请求:

Nginx配置srcache_nginx模块搭配Redis建立缓存系统

再次请求:

Nginx配置srcache_nginx模块搭配Redis建立缓存系统

6. 查看redis是否缓存以及过期时间

Nginx配置srcache_nginx模块搭配Redis建立缓存系统

PS:srcache-nginx-module模块指令说明:
srcache_fetch
语法:srcache_fetch <method> <uri> <args>"htmlcode">

srcache_store_hide_header X-Foo;
srcache_store_hide_header Last-Modified;
srcache_store_pass_header

语法:srcache_store_pass_header <header>
默认值:no
配置段:http, server, location, location if
默认情况下,除了以下头缓存所有响应头:

  • Connection
  • Keep-Alive
  • Proxy-Authenticate
  • Proxy-Authorization
  • TE
  • Trailers
  • Transfer-Encoding
  • Upgrade
  • Set-Cookie

可以缓存多个响应头,不区分大小写。如

srcache_store_pass_header Set-Cookie;
srcache_store_pass_header Proxy-Autenticate;

srcache_methods
语法:srcache_methods <method>...
默认值:srcache_methods GET HEAD
配置段:http, server, location
srcache_ignore_content_encoding
语法:srcache_ignore_content_encoding on|off
默认值: srcache_ignore_content_encoding off
配置段:http, server, location, location if
内容是否编码。
建议后端服务器禁用gzip/deflate压缩。在nginx.conf配置:

proxy_set_header Accept-Encoding "";

srcache_request_cache_control
语法:srcache_request_cache_control on|off
默认值:srcache_request_cache_control off
配置段:http, server, location
当该指令为on时,请求头Cache-Control和Pragma按照下面的方法处理:
1. srcache_fetch查询缓存操作时,当请求头Cache-Control: no-cache 、 Pragma: no-cache 将跳过。
2. srcache_store存入缓存操作时,当请求头Cache-Control: no-store将跳过。
当该指令为off时,将禁用此功能,对于繁忙的站点依赖缓存加速被认为是最安全的。
srcache_response_cache_control
语法:srcache_response_cache_control on|off
默认值:srcache_response_cache_control on
配置段:http, server, location
当该指令为on时,响应头Cache-Control和Expires按照下面的方法处理:

Cache-Control: private skips srcache_store,
Cache-Control: no-store skips srcache_store,
Cache-Control: no-cache skips srcache_store,
Cache-Control: max-age=0 skips srcache_store,
Expires: <date-no-more-recently-than-now> skips srcache_store.

该指令优先级比srcache_store_no_store,srcache_store_no_cache,srcache_store_private高。
srcache_store_no_store
语法:srcache_store_no_store on|off
默认值:srcache_store_no_store off
配置段:http, server, location
开启该指令,将强制响应头Cache-Control: no-store。默认为关闭。
srcache_store_no_cache
语法:srcache_store_no_cache on|off
默认值:srcache_store_no_cache off
配置段:http, server, location
开启该指令,将强制响应头Cache-Control: no-cache。默认为关闭。
srcache_store_private
语法:srcache_store_private on|off
默认值:srcache_store_private off
配置段:http, server, location
开启该指令,将强制响应头Cache-Control: private。默认为关闭。
srcache_default_expire
语法:srcache_default_expire <time>
默认值:srcache_default_expire 60s
配置段:http, server, location, location if
控制默认过期时间。当响应头既没有Cache-Control: max-age=N也没有指定Expires时,允许的$srcache_expire变量值。
该值必须小于597hours。
srcache_max_expire
语法:srcache_max_expire <time>
默认值:srcache_max_expire 0
配置段:http, server, location, location if
控制最大缓存时间,此设置优先级高于其他计算方法。
该值必须小于597hours。
默认为0,不限制。
