1、准备工具 Xshell和Xftp,连接上服务器

2、下载 jdk-7u76-linux-x64.tar.gz 安装包到 /usr/local/目录

3、解压缩 tar xvf jdk-7u76-linux-x64.tar.gz 到目录/usr/local/jdk ，删除压缩包 rm jdk-7u76-linux-x64.tar.gz

4、设置jdk环境变量 vim /etc/profile

export JAVA_HOME=/usr/local/jdk export JRE_HOME=$JAVA_HOME/jre export PATH=$PATH:$JAVA_HOME/bin export CLASSPATH=./:$JAVA_HOME/lib:$JAVA_HOME/jre/lib

5、使profile配置生效。命令行：source /etc/profile

6、验证安装 java -version 、 javac

7、下载 apache-tomcat-8.0.39.tar.gz 到/usr/local/目录

8、解压缩 tar xvf apache-tomcat-8.0.39.tar.gz 到目录/usr/local/tomcat ，删除压缩包 rm apache-tomcat-8.0.39.tar.gz

9、配置环境变量 vim /etc/profile.d/tomcat.sh

CATALINA_BASE=/usr/local/tomcatPATH=$CATALINA_BASE/bin:$PATHexport PATH CATALINA_BASE

. /etc/profile.d/tomcat.sh

10、配置server.xml

<Service name="Catalina"> <Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> <Engine name="Catalina" defaultHost="x.x.x.x"> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> <Host name="x.x.x.x" appBase="project/ccnulife" unpackWARs="true" autoDeploy="true"> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> <Context path="" docBase="/usr/local/apache-tomcat-8.0.39/ccnulife" reloadable="true" crossContext="true"/> </Host> </Engine> 11、我使用的centos7.2 需要开启80端口

firewall-cmd --zone=public --add-port=80/tcp --permanent 1 systemctl restart firewalld .service

12、如果是腾讯云还要在安全组添加80端口开放

13、在域名解析面板配置域名和ip的映射，端口无需填写。

14、启动tomcat

在tomcat所在目录 ./startup.sh
