Linux下Tomcat安装、配置

• /etc/profile、/etc/profile.d和.bash_profile区别

/etc/profile和/etc/profile.d区别

.bash_profile 是存放用户的全局变量

/.etc/profile是文件，存放全局的环境变量

/etc/profile.d是目录，存放各个分类定义的全局环境变量

• tomcat安装

从http://tomcat.apache.org/官网下载

解压并拷贝到/usr/local/tomcat目录下

       tar -xzvf apache-tomcat-7.0.55.tar.gz
       mv apache-tomcat-7.0.55 /usr/local/tomcat

• 配置tomcat自启动

拷贝tomcat提供的启动/停止脚本

       cp /usr/local/tomcat/bin/catalina.sh /etc/init.d/tomcat
       vi /etc/init.d/tomcat

       /*在脚本中添加以下注释语句，告诉系统，tomcat服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。*/
       # chkconfig:   2345 90 10

       /*文件中注释厦门设置tomcat环境变量,jdk环境变量请另行设置*/
       CATALINA_HOME=/usr/local/tomcat7
       CATALINA_BASE=$CATALINA_HOME
       CATALINA_TMPDIR=$CATALINA_HOME/temp
       #CATALINA_PID=
       JAVA_HOME=/usr/local/jdk1.8
       JRE_HOME=/usr/local/jdk1.8/jre
       export CATALINA_HOME CATALINA_BASE CATALINA_TMPDIR

将tomcat设置为服务

       chmod a+x /etc/init.d/tomcat
       chkconfig --add tomcat

       #查看服务是否设置成功
       chkconfig --list tomcat

#以下为服务开启命令

       /*开启服务*/
       chkconfig tomcat on
       /*查看服务*/
       chkconfig --list
