RedHat7安装Tomcat

编译安装Tomcat

1. 下载jdk （http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html）
2. 解压jdk
   # tar -zxvf jdk-8u65-linux-x64.gz -C /usr/local
   # ln -sv /usr/local/jdk1.8.0_65 /usr/local/jdk
3. 设置jdk环境变量
   # vi /etc/profile.d/java.sh
   

   # Set java environment
   JAVA_HOME=/usr/local/jdk
   PATH=$PATH:$JAVA_HOME/bin
   CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
   export JAVA_HOME PATH CLASSPATH

   # source /etc/profile.d/java.sh

4. 下载Tomcat
   # wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-8/v8.0.29/bin/apache-tomcat-8.0.29.tar.gz
5. 安装Tomcat
   # tar -zxvf apache-tomcat-8.0.29.tar.gz -C /usr/local
   # ln -sv /usr/local/apache-tomcat-8.0.29 /usr/local/tomcat
6. 新建网站根目录并更改SELinux类型
   # mkdir -p /data/www && chcon -t httpd_sys_content_t -R /data/www/
7. 修改Tomcat网站根目录
   # vi /usr/local/tomcat/conf/server.xml
   在<Host></Host>节点中增加一行
   <Context path="" docBase="/data/www" debug="0" reloadable="true" crossContext="true" />
8. 添加tomcat用户和用户组
   # useradd -r -M -s /sbin/nologin tomcat
9. 修改Tomcat安装目录属组
   # chown -R tomcat:tomcat /usr/local/tomcat/
10. 创建Tomcat自启动脚本
    # cd /usr/local/tomcat/bin
    # tar -zxvf commons-daemon-native.tar.gz
    # cd commons-daemon-1.0.10-native-src/unix
    # ./configure --with-java=/usr/local/jdk
    # make
    # cp jsvc ../..
    # cd ../..
    # cp daemon.sh /etc/init.d/tomcat
11. 修改Tomcat自启动脚本
    # vi /etc/init.d/tomcat
    增加# chkconfig: - 80 20一行，如下所示：
    

    #!/bin/sh
    #
    # chkconfig: - 80 20                         
    #                                           
    # Licensed to the Apache Software Foundation (ASF) under one or more

    在注释后增加3行

    JAVA_HOME=/usr/local/jdk
    CATALINA_HOME=/usr/local/tomcat
    TOMCAT_USER=tomcat
    如下所示：

12. # -----------------------------------------------------------------------------
    # Commons Daemon wrapper script.
    # -----------------------------------------------------------------------------
    JAVA_HOME=/usr/local/jdk
    CATALINA_HOME=/usr/local/tomcat
    TOMCAT_USER=tomcat
    
    # resolve links - $0 may be a softlink

13. 设置Tomcat服务自启动
    # chmod +x /etc/init.d/tomcat
    # chkconfig tomcat on
14. 启动Tomcat服务
    # service tomcat start
