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 yespidfile /var/run/redis-6379.pidport 6379bind 127.0.0.1timeout 0tcp-keepalive 0loglevel noticelogfile stdoutdatabases 16stop-writes-on-bgsave-error yesrdbcompression yesrdbchecksum yesdbfilename dump.rdbslave-serve-stale-data yesslave-read-only yesrepl-disable-tcp-nodelay noslave-priority 100maxmemory 8096mbmaxmemory-policy volatile-ttlappendonly noappendfsync everysecno-appendfsync-on-rewrite noauto-aof-rewrite-percentage 100auto-aof-rewrite-min-size 64mblua-time-limit 5000slowlog-log-slower-than 10000slowlog-max-len 128hash-max-ziplist-entries 512hash-max-ziplist-value 64list-max-ziplist-entries 512list-max-ziplist-value 64set-max-intset-entries 512zset-max-ziplist-entries 128zset-max-ziplist-value 64activerehashing yesclient-output-buffer-limit normal 0 0 0client-output-buffer-limit slave 256mb 64mb 60client-output-buffer-limit pubsub 32mb 8mb 60hz 10aof-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.Vevb.com.conf;}

# vim vhosts/test.Vevb.com.conf
