2、如何使用httpd反代用户请求

（1）方法一

apache:

mod_proxy

mod_proxy_http

mod_proxy_balancer

tomcat:

[[email protected] nginx]# systemctl stop nginx.service

[[email protected] nginx]# systemctl disable nginx.service

[[email protected] nginx]# yum -y install httpd

[[email protected] ~]# cd /etc/httpd/conf

[[email protected] conf]# vim httpd.conf 

注释掉

#DocumentRoot "/var/www/html"

[[email protected] conf]# cd ../conf.d/

[[email protected] conf.d]# vim vhost.conf

<proxy balancer://lbcluster1>

BalancerMember http://192.168.1.132:8080 loadfactor=10 route=TomcatA

（1）反向代理

[[email protected] ~]# cd /etc/httpd/conf.d/

[[email protected] conf.d]# mv vhost.ajp.conf{,.bak}

[[email protected] conf.d]# vim mod_jk.conf

LoadModule jk_module modules/mod_jk.so

JkWorkersFile  /etc/httpd/conf.d/workers.properties

JkLogFile  logs/mod_jk.log

JkLogLevel  debug

JkMount  /*  TomcatA

JkMount  /status/  stat1

[[email protected] conf.d]# vim /etc/httpd/conf.d/workers.properties

worker.list=TomcatA,stat1

worker.TomcatA.port=8009

worker.TomcatA.host=192.168.1.132

worker.TomcatA.type=ajp13

worker.TomcatA.lbfactor=1

worker.stat1.type = status

[[email protected] conf.d]# httpd -t

[[email protected] conf.d]# systemctl restart httpd.service

（2）负载均衡

[[email protected] ~]# cd /etc/httpd/conf.d/

[[email protected] conf.d]# vim mod_jk.conf

Session会话保持机制的原理与Tomcat Session Cluster示例

一.Session的定义 在计算机科学中,特别是在网络中,session是两个或更多个通信设备之间或计算机和用户之间的临时和交互式信息交换.session在某个时间点建立,然后在之后的某一时间点拆除.建立的通信session可以在每个方向上涉及多个消息.session通常是有状态的,这意味着至少一个通信部分需要保存关于会话历史的状态信息以便能够进行通信,而在无状态通信中,通信由具有响应的独立请求组成.--Wikipedia Session:在计算机中,尤其是在网络应用中,称为"会话控制"

memcached性能监控

1.安装启动memcached 安装: yum -y install memcached 启动: chkconfig --level 2345 memcached on service memcached start 查看状态: memcached-tool  127.0.0.1:11211 stats 重要指标: cmd_get  查询缓存次数 cmd_set 设置key=>value的次数,没找到就写缓存 get_hits 总命中数get_misses总未命中数 配置文件: /etc/sys

Tomcat（JVM）性能调优

Tomcat架构图 Tomcat与JVM版本优化Tomcat的运行是基于Java的虚拟机.SUN的JVM动态库有client和server两个版本,分别针对桌面应用和服务器应用做了相应的优化,client版本加载速度较快,server版本加载速度较慢但运行起来较快.在命令行输入 java -version 可以看到jvm目前配置的是哪个版本.如果要修改jvm的版本,可更改默认java.exe调用的jvm.dll,这个由jvm.cfg决定.编辑%JAVA_HOME%/jre/lib/i386/jv

Memcached笔记——（一）安装&amp;常规错误&amp;监控

设置TOMCAT的JVM虚拟机内存大小

你知道如何设置TOMCAT的JVM虚拟机内存大小吗,这里和大家分享一下,JAVA程序启动时JVM都会分配一个初始内存和最大内存给这个应用程序.这个初始内存和最大内存在一定程度都会影响程序的性能. 设置TOMCAT的JVM虚拟机内存大小 Tomcat本身不能直接在计算机上运行,需要依赖于硬件基础之上的操作系统和一个java虚拟机.JAVA程序启动时JVM都会分配一个初始内存 和最大内存给这个应用程序.这个初始内存和最大内存在一定程度都会影响程序的性能.比如说在应用程序用到最大内存的时候,JVM是要

云计算高级培训，Tomcat运维JVM 虚拟机常识

云计算高级培训,Tomcat运维JVM 虚拟机常识,作为了解JVM 虚拟机的开始.我们很有必要弄明白以下问题. 所谓虚拟机,就是一台虚拟的计算机.他是一款软件,用来执行一系列虚拟计算机指令.大体上,虚拟机可以分为系统虚拟机和程序虚拟机.大名鼎鼎的VisualBox.VMware就属于系统虚拟机.他们完全是对物理计算机的仿真.提供了一个可以运行完整操作系统的软件平台. 程序虚拟机的典型代表就是Java虚拟机,它专门为执行单个计算机程序而设计,在Java虚拟机中执行的指令我们称为Java字节码指令.

Tomcat调优总结（Tomcat自身优化、Linux内核优化、JVM优化）

Tomcat自身的调优是针对conf/server.xml中的几个参数的调优设置.首先是对这几个参数的含义要有深刻而清楚的理解.以tomcat8.5为例,讲解参数. 同时也得认识到一点,tomcat调优也受制于linux内核.linux内核对tcp连接也有几个参数可以调优. 因此我们可以将tomcat调优分为linux内核优化.java虚拟机调优和tomcat自身的优化. 一.Tomcat自身优化 1. maxThreads :tomcat创建的最大线程数,也就是同时处理的请求最大并发数.默认值
