我现在一个项目通过nginx用lua调用redis，大致配置如下
upstream redis {
server 127.0.0.1:6379 weight=1;
keepalive 1024;
}
#一个请求
location ~* req_xxx {
set $redis_key $arg_xxx;
content_by_lua_file '
local parser = require("redis.parser")
local res = ngx.location.capture("/redis_get", {args = { key = ngx.var.redis_key }})
//...
ngx.print(res.body)
'
error_page error_code_xxx =200 @backend_xxx;
}
#从redis读数据
location /redis_get {
internal;
set_unescape_uri $key $arg_key;
redis2_query get $key;
redis2_pass redis;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_connect_timeout 60;
proxy_send_timeout 60;
proxy_read_timeout 60;
proxy_buffer_size 4k;
proxy_buffers 512 8k;
proxy_busy_buffers_size 8k;
proxy_temp_file_write_size 64k;
}
在连接redis时，client个数特别奇怪，会时不时的猛增一下,没有曲线直接上去，而且会持续5分钟,监控图如下：
哪位可以解答下原因
