Linux 上安装 Tomcat8教程

一、配置主机

systemctl stop firewalld
systemctl disable firewalld

setenforce poermissive

hostnamectl set-hostname tomcat

二、安装JDK

1.到oracle网站上下载JDK
https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html#license-lightbox
2.解压JDK
tar -xf jdk-8uXXXXX -C /usr/local
ln -s /usr/local/jdk1.8.0\_281/ /usr/local/jdk

cat >> /etc/profile <<'EOF'
export JAVA\_HOME=/usr/local/jdk
export CLASSPATH=$CLASSPATH:$JAVA\_HOME/lib:$JAVA\_HOME/fre/lib
export PATH=$JAVA\_HOME/bin:$JAVA\_HOME/fre/bin:$PATH
EOF

\#测试是否安装成功
java -version

三、安装Tomcat
到tomcat.apache.org上下载Tomcat
https://mirrors.bfsu.edu.cn/apache/tomcat/tomcat-8/v8.5.69/bin/apache-tomcat-8.5.69.tar.gz

tar -xf apache-tomcat-8.5.69.tar.gz -C /usr/local/

ln -s /usr/local/apache-tomcat-8.5.69/ /usr/local/tomcat

/usr/local/tomcat/bin/startup.sh
/usr/local/tomcat/bin/shutdown.sh

登录tomcat，如果能正常登录说明安装成功

四、tomcat开启远程管理Manager App
1.修改/user/local/tomcat/conf/context.xml
将context的如下内容删除

<!--

WEB-INF/web.xml
${catalina.base}/conf/web.xml

<!--

-->
-->

修改context的内容如下：

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="^.*$" />

2.在/usr/local/tomcat/conf/tomcat-users.xml文件末尾增加如下角色及用户

3.配置远程访问manager
在/usr/local/tomcat/conf 目录下的Catalina/localhost目录下新建一个manager.xml文件，写入如下内容：

<Context privileged="true" antiResourceLocking="false"
docBase="${catalina.home}/webapps/manager">

4.然后重启tomcat，登录web管理页面访问manager app

5.如果需要访问host-manager，则要修改如下的内容：

vi /usr/local/tomcat/webapps/host-manager/META-INF/context.xml

<CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor"
sameSiteCookies="strict" />
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="\d+\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
