首先下载解压版Tomcat,解压多个tomcat然后修改文件夹名:[图片]每个tomcat做如下操作:1. 环境变量(不需要)设置CATALINA_HOME1为tomcat1的目录设置CATALINA_BASE1为tomcat1的目录2. 进入conf文件夹,修改server.xml中的8080,8005,8009端口3. 替换CATALINA_HOME及CATALINA_BASE进入tomcat1的bin目录,将catalina.bat,startup.bat,service.bat进行如下替换替换CATALINA_HOME为CATALINA_HOME1替换CATALINA_BASE为CATALINA_BASE1替换完成后,在bin目录下执行cmd命令./service.bat install你的tomcat服务名如下提示代表安装成功，执行netstarttomcat服务名 即可启动tomcat[图片]在服务列表中可以看到刚刚安装的服务：[图片]记录： jenkins部署至tomcat默认项目时，需将默认的ROOT文件夹删掉，context path填/而不是/ROOT，否则报错：java.net.SocketException: Software caused connection abort: recv failed[图片]

1.安装新版内核yum install -y https://github.com/zhangxiaoqiang1998/bbrplus/raw/master/centos7/x86_64/kernel-4.14.129-bbrplus.rpm2.切换启动内核grub2-set-default 'CentOS Linux (4.14.129) 7 (Core)'3.启用 fq bbrplusecho "net.core.default_qdisc=fq" /etc/sysctl.confecho "net.ipv4.tcp_congestion_control=bbrplus" /etc/sysctl.conf4.重启后检查,如果显示为bbrplus则成功uname -r5.查看查看内核是否已开启BBRpuls显示带有bbrplus则成功sysctl net.ipv4.tcp_available_congestion_control6.查看bbr是否启动lsmod | grep bbrplus

一些自己上传的二进制运行文件没有自启支持，因此手动创建在/etc/init.d/目录下创建一个文件#!/bin/sh /etc/rc.commonSTART=51start() {echo 'starting service'# script here}stop(){echo 'stop service'ps | grep xxx | awk 'NR==1{print $1}' | xargs kill}文件头的shebang为#!/bin/sh /etc/rc.commonSTART=51代表此脚本将在START=50脚本执行后执行start及stop函数为服务启动启动停止执行的内容使用/etc/init.d/xxx start/stop/enable/disable分别为启动、停止、开启自启、禁止自启操作：By this rc.common template, the available commands for an init scripts are as follows: start Start the service stop Stop the service restart Restart the service reload Reload configuration files (or restart if that fails) enable Enable service autostart disable Disable service autostart注: 还有另一种注册服务方式 - procd init script，专注于运行在后台的服务，后续有机会了解一下：https://openwrt.org/docs/guide-developer/procd-init-scripts参考https://openwrt.org/docs/techref/initscripts

nginx会忽略带下划线的header，官方对header的说明如下：Syntax:ignore_invalid_headers on | off;Default:ignore_invalid_headers on;Context:http, serverControls whether header fields with invalid names should be ignored. Valid names are composed of English letters, digits, hyphens, and possibly underscores (as controlled by the underscores_in_headers directive).默认忽略非法的header，合法的header包括：字母、数字、杠(-)、或者下划线(默认禁用，通过 underscores_in_headers 参数指定）推荐修改为符合要求的heder参数名，若一定要用下划线，可以在nginx.conf的http中允许转发带下划线的header：nginx.conf:ignore_invalid_headers off;参考http://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers
