Nginx配置srcache_nginx模块搭配Redis建立缓存系统

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] "$request" '
                    '"$status" $body_bytes_sent "$http_referer" '
                    '"$http_user_agent" "$http_x_forwarded_for" '
                    '"$gzip_ratio" $request_time $bytes_sent $request_length';
 
    log_format srcache_log '$remote_addr - $remote_user [$time_local] "$request" '
                '"$status" $body_bytes_sent $request_time $bytes_sent $request_length '
                '[$upstream_response_time] [$srcache_fetch_status] [$srcache_store_status] [$srcache_expire]';
 
    set_real_ip_from 10.0.0.0/8;
    real_ip_header X-Forwarded-For;
 
    include     vhosts/test.jb51.net.conf;
}

# vim vhosts/test.jb51.net.conf

        }
 
        include fastcgi_params;

     }
 
    location = /redis {

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