centos7 jsp环境部署

一：安装jdk

1.官网下载jdk : http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

下载 jdk-8u144-linux-x64.rpm 后缀的

如 : wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie"   http://download.oracle.com/otn-pub/java/jdk/8u171-b11/512cd62ec5174c3487ac17c61aaa89e8/jdk-8u171-linux-x64.rpm?AuthParam=1524396705_1ef5fded3e0877234c4d0833bceb088f

2.下载完成后安装

rpm -ivh jdk-8u151-linux-x64.rpm

安装后使用 rpm -ql jdk | tail -10  查看安装路径

2.1添加环境变量

[root@essun bin]# vim /etc/profile.d/java.sh

export JAVA_HOME=/usr/java/latest

export PATH=$JAVA_HOME/bin:$PATH

#注：$JAVA_HOME/bin一定要写在前面，否则将引用的是系统自带的java环境

[root@essun bin]source /etc/profile.d/java.sh

[root@essun bin]# java -version

java version"1.7.0_55"

Java(TM) SE Runtime Environment (build 1.7.0_55-b13)

Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)

到此，jdk安装完成。

二：安装tomcat

1.下载tomcat

https://tomcat.apache.org/download-70.cgi

wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie"   http://mirrors.hust.edu.cn/apache/tomcat/tomcat-7/v7.0.86/bin/apache-tomcat-7.0.86.tar.gz

2.安装

tar xf apache-tomcat-7.0.53.tar.gz -C /usr/java/

cd /usr/java

ln -sv apache-tomcat-7.0.53 tomcat

3.添加环境变量

[root@essun tomcat]# vim /etc/profile.d/tomcat.sh

export CATALINA_HOME=/usr/java/tomcat

export PATH=$PATH:$CATALINA_HOME/bin

[root@essun bin]source /etc/profile.d/tomcat.sh

4.启动服务

[root@essun tomcat]# catalina.sh start

Using CATALINA_BASE:/usr/local/tomcat

Using CATALINA_HOME:/usr/local/tomcat

Using CATALINA_TMPDIR:/usr/local/tomcat/temp

Using JRE_HOME:/usr/java/latest

Using CLASSPATH:/usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar

Tomcat started.

[root@essun tomcat]# ss -tnlp | grep 8080

LISTEN     0      100                      :::8080                    :::*users:(("java",28017,42))

[root@essun tomcat]# ss -tnlp | grep java

LISTEN     0      100                      :::8080                    :::*users:(("java",28017,42))

LISTEN     0      1          ::ffff:127.0.0.1:8005                    :::*users:(("java",28017,45))

LISTEN     0      100                      :::8009                    :::*users:(("java",28017,43))

三：配置防火墙开启端口

CentOS7防火墙换用Friewalld了，所以要用以下命令将端口号加进防火墙：

firewall-cmd --zone=public --add-port=8080/tcp --permanent

firewall-cmd --reload

四：外网访问

ip:8080 效果如下
