如何在服务器上放网站wordpress 短信登录密码
在部署mysql 主主高可用时,使用haproxy进行负载,在服务部使用的情况下发现服务器cpu占比高,负载也高,因此急需解决这个问题。
1.解决前现状
1.1 部署配置文件
cat > haproxy.cfg << EOF
globalmaxconn     4000nbthread    2daemon 
defaultslog     globallog 127.0.0.1 local3mode    httpoption  tcplogoption  dontlognullretries 10option redispatchmaxconn         2000timeout connect         30stimeout client          10mtimeout server          10m#timeout http-keep-alive 10stimeout check           10s

EOFcat > dokcer-stark-haproxy.yml << EOF
version: '3'networks:liuhm-net:external: true services:haproxy:image: haproxy:alpinehostname: haproxyvolumes:- "${PWD}/haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg"- "/etc/localtime:/etc/localtime:ro"restart: alwaysprivileged: trueports:- 8888:8888- 3306:3306networks:- liuhm-netdeploy:mode: global
EOF 

2.解决后
- 修改了镜像版haproxy:2.9.1-alpine
 - 增加了配置 tune.disable-zero-copy-forwarding
 - github 解决问题地址
 
cat > haproxy.cfg << EOF
globalmaxconn     4000nbthread    2daemon ## tune.disable-zero-copy-forwarding必须配置,不然cpu占比很高tune.disable-zero-copy-forwarding                       
defaultslog     globallog 127.0.0.1 local3mode    httpoption  tcplogoption  dontlognullretries 10option redispatchmaxconn         2000timeout connect         30stimeout client          10mtimeout server          10m#timeout http-keep-alive 10stimeout check           10s

实际配置后没有飙升
