Centos6.8 配置 Tomcat

1、安装Tomcat，安装之前必须先安装Java，先安装java

下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html

  (1)：解压安装java

tar zxvf jdk-8u151-linux-x64.tar.gz

  (2)：配置java

mv jdk1.8.0_151/ /usr/local/java
vim /etc/profile.d/java.sh
#写入
export JAVA_HOME=/usr/local/java
export PATH=$PATH:$JAVA_HOME/bin
#保存退出

  (3)：导入环境变量，查看Java版本

source /etc/profile.d/java.sh   #导入环境变量
java -version  #查看JAVA版本

2、下载安装Tomcat

下载地址：https://tomcat.apache.org/download-90.cgi

  (1)：下载解压Tomcat

wget http://mirrors.shuosc.org/apache/tomcat/tomcat-9/v9.0.2/bin/apache-tomcat-9.0.2.tar.gz
tar zxvf apache-tomcat-9.0.2.tar.gz

  (2)：配置、启动Tomcat

mv apache-tomcat-9.0.2 /usr/local/tomcat9
/usr/local/tomcat9/bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat9
Using CATALINA_HOME:   /usr/local/tomcat9
Using CATALINA_TMPDIR: /usr/local/tomcat9/temp
Using JRE_HOME:        /usr/local/java
Using CLASSPATH:       /usr/local/tomcat9/bin/bootstrap.jar:/usr/local/tomcat9/bin/tomcat-juli.jar
Tomcat started.

   (3)：查看Tomcat端口

[root@localhost /]# netstat -anpt | grep 8080
tcp        0      0 :::8080                     :::*                        LISTEN      3350/java  

  (4)：防火墙允许8080端口通过，Tomcat默认端口是8080

vim /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT   #添加

#保存脱出

service iptables restart

   (5)：访问浏览器测试，http://127.0.0.1:8080，如果出现下图，则说明Tomcat成功启动

  (6)：如果想关闭Tomcat

/usr/local/tomcat9/bin/shutdown.sh
