面板安装的openresty如何集成lua-resty-upstream-healthcheck健康检查

[Aliang-code]

默认引用的WAF配置中有如下配置（include /usr/local/openresty/1pwaf/data/conf/waf.conf;）

lua_shared_dict waf_req_count 10m;
lua_shared_dict waf 50m;
lua_shared_dict waf_block_ip 10m;
lua_shared_dict waf_ip_arr 20m;
lua_shared_dict waf_limit 10m;
lua_shared_dict waf_sql 200m;
lua_shared_dict waf_locks 100k;

lua_code_cache on;
lua_package_path "/usr/local/openresty/1pwaf/?.lua;/usr/local/openresty/1pwaf/lib/?.lua;;";
init_by_lua_file  /usr/local/openresty/1pwaf/init.lua;
access_by_lua_file /usr/local/openresty/1pwaf/waf.lua;
log_by_lua_file /usr/local/openresty/1pwaf/log_and_traffic.lua;
init_worker_by_lua_file /usr/local/openresty/1pwaf/worker.lua;

其中的lua_package_path和init_worker_by_lua_file都是全局唯一的设置，那如何在不关闭WAF功能的情况下配置lua-resty-upstream-healthcheck呢？只能注释掉这两项重新写吗，我注释后尝试以下配置会报错

lua_package_path "/usr/local/openresty/lualib/?.lua;/usr/local/openresty/1pwaf/?.lua;/usr/local/openresty/1pwaf/lib/?.lua;/usr/local/openresty/1pwaf/worker.lua;;";
lua_shared_dict healthcheck 1m;
lua_socket_log_errors off;
init_worker_by_lua_block {
    require "worker" #1panel自带WAF脚本
    local hc = require "resty.upstream.healthcheck"

    local ok, err = hc.spawn_checker{
        shm = "healthcheck", 
        upstream = "blog",      #upstream名称
        type = "http",          #健康检查请求协议
        http_req = "GET /wp-content/ HTTP/1.0\r\nHost: blog.aliang-zh.top\r\n\r\n", #健康检查请求路径
        port = nil,             #健康检查请求端口，默认使用upstream端口
        interval = 2000,        #检查间隔毫秒
        timeout = 1000,         #检查超时毫秒
        fall = 3,               #检查失败几次后下线
        rise = 2,               #检查成功几次后上线
        valid_statuses = {200,301,302},  #成功状态码列表
        concurrency = 10,       #并发数
        -- ssl_verify = true,   #是否校验证书，仅https有效，默认true
        -- host = foo.com,      #校验证书域名，仅https有效，默认空
    }
    if not ok then
        ngx.log(ngx.ERR, "failed to spawn health checker: ", err)
        return
    end

    #多个upstream复制hc.spawn_checker即可
}

好吧我是智障，lua的注释符号是--而不是#
注释掉/opt/1panel/apps/openresty/openresty/1pwaf/data/conf/waf.conf的lua_package_path和init_worker_by_lua_file，使用如下配置既可

#openresty健康检查
lua_package_path "/usr/local/openresty/lualib/?.lua;/usr/local/openresty/1pwaf/?.lua;/usr/local/openresty/1pwaf/lib/?.lua;;";
lua_shared_dict healthcheck 1m;
lua_socket_log_errors off;
init_worker_by_lua_block {
    require "worker" --1panel自带WAF脚本
    local hc = require "resty.upstream.healthcheck"

    local ok, err = hc.spawn_checker{
        shm = "healthcheck", 
        upstream = "blog",      --upstream名称
        type = "http",          --健康检查请求协议
        http_req = "GET /wp-content/ HTTP/1.0\r\nHost: blog.aliang-zh.top\r\n\r\n", --健康检查请求路径
        port = nil,             --健康检查请求端口，默认使用upstream端口
        interval = 2000,        --检查间隔毫秒
        timeout = 1000,         --检查超时毫秒
        fall = 3,               --检查失败几次后下线
        rise = 2,               --检查成功几次后上线
        valid_statuses = {200,301,302},  --成功状态码列表
        concurrency = 10,       --并发数
        -- ssl_verify = true,   --是否校验证书，仅https有效，默认true
        -- host = foo.com,      --校验证书域名，仅https有效，默认空
    }
    if not ok then
        ngx.log(ngx.ERR, "failed to spawn health checker: ", err)
        return
    end

    --多个upstream复制hc.spawn_checker即可
