简单介绍:

说明: Tomcat是Apache软件基金会项目中的一个核心项目,它具有处理HTML页面的功能(性能不如Nginx/Apache),而且是Servlet和JSP容器(在标准的MVC架构中,Servlet作为Controller控制层接受用户请求并转发给相应的Action处理,JSP作为View主要用来产生动态页面),独立的Servlet容器是Tomcat的默认模式,相对于Nginx/Apache常用作静态内容服务来说,Tomcat常用作后端应用服务.


版本选择:

Tomcatapache-tomcat-7.0.72.tarhttp://tomcat.apache.org/download-70.cgi
Jdkjdk-7u80-linux-x64.tar.gzhttp://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html

说明: Tomcat以Java编写,安装对应的完整的Java运行环境(强烈推荐Jdk而非Jre),个人经验以版本选择以上个稳定版为主,个人选择7.0.x版

通用安装:

略

绿色安装:

# 安装Jdk

mkdir -p /xm-workspace/xm-webs/xmcloud/jdk/
tar -zxvf jdk-7u80-linux-x64.tar.gz -C /xm-workspace/xm-webs/xmcloud/jdk/
cd /xm-workspace/xm-webs/xmcloud/jdk/
mv jdk1.7.0_80/* ./ && rm -rf rm -rf jdk1.7.0_80

# 安装Tomcat

groupadd tomcat
useradd -M -s /bin/bash -g tomcat tomcat
usermod -L tomcat
mkdir -p /xm-workspace/xm-webs/xmcloud/tomcat8081
tar -zxvf apache-tomcat-7.0.72.tar.gz -C /xm-workspace/xm-webs/xmcloud/tomcat8081/
chown tomcat.tomcat /xm-workspace/xm-webs/xmcloud/tomcat8081
cd /xm-workspace/xm-webs/xmcloud/tomcat8081/
mv apache-tomcat-7.0.72/* ./ && rm -rf apache-tomcat-7.0.72
chown -R tomcat ./*

# 设置环境变量(头部添加环境变量即可)

vim /xm-workspace/xm-webs/xmcloud/tomcat8081/bin/catalina.sh
PORT=8081
HOME=`pwd|sed "s/\/tomcat${PORT}.*//g"`
export JRE_HOME="${HOME}/jdk/jre"
export JAVA_OPTS="-server -Xms1024m -Xmx1024m -Xmn384m -XX:PermSize=64m -XX:MaxPermSize=128m -XX:+UseParallelOldGC -XX:+PrintGCDateStamps -XX:+PrintGCDetails -Xloggc:${HOME}/tomcat${PORT}/logs/gc.log -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${HOME}/tomcat${PORT}/heapdump.bin"

说明: -server表示启用jdk的server版,-Xms1024m表示java虚拟机初始化时最小内存,-Xmx1024m表示java虚拟机可使用的最大内存,-XX:PermSize=64m -XX:MaxPermSize=128m主要是为了防止堆栈永久区溢出设置,所以可以保持默认或是任意合理值即可,-XX:+UseParallelOldGC -XX:+PrintGCDateStamps -XX:+PrintGCDetails -Xloggc:${HOME}/tomcat${PORT}/logs/gc.log -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${HOME}/tomcat${PORT}/heapdump.bin主要是添加内存溢出导致Tomcat宕掉后日志记录分析使用,生产环境推荐加上.
