安装 memcached
yum install -y memcached #启动memcached服务,端口11211,以nobody身份启动,-d后台模式运行 memcached -p11211 -u nobody -d #将自己的IP设为灰度测试的IP telnet 127.0.0.1 11211 set 119.32.216.122 0 0 1 1 quit
安装 memcached for lua
wget https://github.com/openresty/lua-resty-memcached/archive/v0.11.tar.gz tar -zxvf v0.11.tar.gz mkdir -p /usr/local/share/lua/5.1 cp -r lua-resty-memcached-0.11/lib/resty /usr/local/share/lua/5.1
创建 test.lua 文件
clientIP=ngx.req.get_headers()["X-Real-IP"] if clientIP == nil then clientIP=ngx.req.get_headers()["x_forwarded_for"] end if clientIP == nil then clientIP=ngx.var.remote_addr end local memcached=require "resty.memcached" local memc,err=memcached:new() if not memc then ngx.say("failed to instantiate memc:",err) return end local ok,err =memc:connect("127.0.0.1",11211) if not ok then ngx.say("failed to connect:",err) return end local res,flags,err =memc:get(clientIP) --ngx.say("value key: ",res,clientIP) if err then ngx.say("failed to get clientIP",err) return end if res == "1" then ngx.exec("@server_test") return end ngx.exec("@server_product")
nginx配置
server { listen 8867; server_name www.siguoya.name; root /usr/local/nginx/1.12.1/html; location / { content_by_lua_file /etc/nginx/test.lua; } location /hello { default_type text/plain; content_by_lua 'ngx.say("hello lua")'; } location /ua { default_type text/plain; content_by_lua ' clientIP=ngx.req.get_headers()["USER-AGENT"] ngx.say("IP:",clientIP) '; } location @server_product { default_type text/plain; return 200 'product'; } location @server_test { default_type text/plain; return 200 'test'; } }
由于我们将 119.32.216.122 这个IP添加进了memcached中,因此访问 http://www.siguoya.name:8867/ 的时候,看到的内容就是 test
而开启全局代理之后,发现看到的内容就是 product,这样就实现了针对部分用户进行灰度测试的效果
