openresty + lua 这个地方怎么写

lua-resty-upstream-healthcheck lua-resty-balancer

这两个插件是负载均衡和健康检测。组合到一块我不知道怎么写了。

 upstream webserver { server 127.0.0.1:12354; server 127.0.0.1:12355; server 127.0.0.1:12356 backup; } upstream webserver { server 127.0.0.1; balancer_by_lua_block { local b = require "ngx.balancer" local swrr_up = package.loaded.my_swrr_up -- Note that SWRR picks the first server randomly local server = swrr_up:find() assert(b.set_current_peer(server)) } }
