Nginx做缓存及代理均衡
编译安装缓存nginx:
yum install -y gcc gcc-c++ openssl-devel zlib-devel tar xf pcre-8.34.tar.gz cd pcre-8.34 ./configure && make && make install cd .. wget http://labs.frickle.com/files/ngx_cache_purge-2.3.tar.gz tar xf ngx_cache_purge-2.3.tar.gz -C /opt/app tar xf nginx-1.4.7.tar.gz cd nginx-1.4.7 ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --add-module=/opt/app/ngx_cache_purge-2.1/
这里我添加一块磁盘做缓存
fdisk /dev/sdb n p 1 w q mkfs.ext3 /dev/sdb1 mkdir /cache mount /dev/sdb1 /cache
nginx-cache主要配置:
[root@centos-server ~]# cat /usr/local/nginx/conf/nginx.conf
user www www; worker_processes 1; error_log /usr/local/nginx/logs/error.log crit; pid /usr/local/nginx/nginx.pid; worker_rlimit_nofile 65535; events { use epoll; worker_connections 65535; } http { include mime.types; default_type application/octet-stream; charset utf-8; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 300m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; client_body_buffer_size 512k; proxy_connect_timeout 5; proxy_read_timeout 60; proxy_send_timeout 5; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.1; gzip_comp_level 2; gzip_types text/plainapplication/x-javascript text/css application/xml; gzip_vary on; proxy_temp_path /cache/proxy_temp_dir; proxy_cache_path /cache/proxy_cache_dir levels=1:2 keys_zone=cache_one:200m inactive=1d max_size=30g; upstream backend_server { server 192.168.150.131:80 weight=1 max_fails=2 fail_timeout=30s; server 192.168.150.129:80 weight=1 max_fails=2 fail_timeout=30s; } server { listen 80; server_name localhost; index index.html index.htm; root /cache/web; location / { root /cache/web; index index.html index.htm; proxy_next_upstream http_502 http_504 error timeout invalid_header;#不可达就转发给其它服务器处理 proxy_cache cache_one;#在location匹配的的URL被缓存 proxy_cache_valid 200 304 12h;#对返回状态码200和304的缓存12小时,200表示服务器处理成功,304表示网页内容未改变 proxy_cache_key $host$uri$is_args$args;#设置缓存文件获得文件名的参数 proxy_set_header Host $host; proxy_set_header X-Forwarded-For $remote_addr; proxy_pass http://backend_server; expires 1d; } location ~ /purge(/.*)#设置手动清理缓存 { auth_basic "TDT Center CACHE Center"; # auth_basic_user_file /tmp/htpasswd;#如果想保护缓存安全可以添加验证信息 allow 127.0.0.1; allow 192.168.150.0/24; deny all; proxy_cache_purge cache_one $host$1$is_args$args; } location ~ .*\.(php|jsp|cgi)?$#不缓存动态内容 { proxy_set_header Host $host; proxy_set_header X-Forwarded-For $remote_addr; proxy_pass http://backend_server; } } }
