Centos7安装JDK+部署Tomcat8

Centos7下JDK+Tomcat的部署：

1.安装JDK

　1.1 通过以下命令获得java JDK列表

yum -y list java*

　1.2 通过yum安装JDK

yum -y install java-1.8.0-openjdk*

　等待安装完成

****通过yum默认安装的路径为/usr/lib/jvm/java-版本号（如/usr/lib/jvm/java-1.8.0）****

2.安装Tomcat

　　2.1.在Tomcat官网下载Tomcat8的gz压缩包（附：https://tomcat.apache.org/download-80.cgi）

　　下载得到的压缩包上传到centos的/usr/local/目录

　　2.2 通过ls查看压缩包

[root@VM_0_9_centos jvm]# cd /usr/local/
[root@VM_0_9_centos local]# ls
apache-tomcat-8.5.33.tar.gz  etc    include  lib64    qcloud  share  tomcat
bin                          games  lib      libexec  sbin    src

　　2.3 解压并通过mv移动到tomcat文件夹

[root@VM_0_9_centos local]# tar xvf apache-tomcat-8.5.33.tar.gz

[root@VM_0_9_centos local]# mv apache-tomcat-8.5.33 /usr/local/tomcat/

　　2.4 配置jdk到tomcat

[root@VM_0_9_centos local]# vim /usr/local/tomcat/bin/startup.sh
[root@VM_0_9_centos local]# vim /usr/local/tomcat/bin/shutdown.sh

　　通过vim将以下代码插入到startup.sh和shutdown.sh

export JAVA_HOME=/usr/lib/jvm/java-1.8.0
export TOMCAT_HOME=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar
export PATH=$PATH:/usr/lib/jvm/java-1.8.0/bin:/usr/local/tomcat/bin

　　完成之后是这样的

export JAVA_HOME=/usr/lib/jvm/java-1.8.0
export TOMCAT_HOME=/usr/local/tomcat
export CATALINA_HOME=/usr/local/tomcat
export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar
export PATH=$PATH:/usr/lib/jvm/java-1.8.0/bin:/usr/local/tomcat/bin

os400=false
case "`uname`" in
OS400*) os400=true;;
esac

# resolve links - $0 may be a softlink
PRG="$0"

　　2.5 这时候就已经配置好了，最后将tomcat的8080端口号修改为tcp/ip默认的80端口

[root@VM_0_9_centos local]# vim /usr/local/tomcat/conf/server.xml

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

改为

    <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

　　2.6 启动tomcat

[root@VM_0_9_centos local]# /usr/local/tomcat/bin/startup.sh

完成后，直接输入ip/域名就能访问tomcat了
