需求描述：
根據(jù)IP訪問間隔县貌，將請求轉發(fā)到不同證書的負載均衡器上
使用OpenResty進行upstream balancer_by_lua_block配置：
upstream server {
# 占位server
server 127.0.0.1:80;
balancer_by_lua_block {
local filer = io.open("somewhere/ipaddrs/".. ngx.var.remote_addr, "r")
local diffT = 100
if (filer ~= nil) then
local oldT = filer:read()
local oldT1 = tonumber(oldT)
diffT = os.time() - oldT1
end
ngx.log(ngx.ERR, "------------: " .. diffT )
local file = io.open("somewhere/ipaddrs/".. ngx.var.remote_addr, "w")
file:write(os.time())
file:close()
if diffT < 6 then
local balancer = require "ngx.balancer"
-- first ssl nginx
local host = "ur nginx IP"
local port = ur nginx Port
local ok, err = balancer.set_current_peer(host, port)
if not ok then
ngx.log(ngx.ERR, "failed to set the current peer: ", err)
return ngx.exit(500)
end
end
}
}
配置多臺代理
通過NFS共享ipaddrs目錄
