centos7 下载安装tomcat9

需要Java环境

https://www.cnblogs.com/sea-stream/p/10404360.html

官网下载安装包

wget http://archive.apache.org/dist/tomcat/tomcat-9/v9.0.0.M18/bin/apache-tomcat-9.0.0.M18.tar.gz

解压

tar -zxvf apache-tomcat-9.0.0.M18.tar.gz

移动目录

sudo mv ~/apache-tomcat-9.0.0.M18 /usr/local/tomcat

配置自启动，切换至Tomcat的bin目录执行vi setenv.sh，并按i进入编辑模式，拷贝以下代码粘贴

#add tomcat pid
CATALINA_PID="$CATALINA_BASE/tomcat.pid"

#add java opts
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"

添加权限

sudo chmod +x setenv.sh

配置service

sudo vi /usr/lib/systemd/system/tomcat.service

加入如下内容

[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
PIDFile=/usr/local/tomcat/tomcat.pid
ExecStart=/usr/local/tomcat/bin/startup.sh
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true
[Install]
WantedBy=multi-user.target

配置环境变量

sudo vi /etc/profile

加入如下代码

export CATALINA_HOME=/usr/local/tomcat
export PATH=$TOMCAT_HOME/bin:$PATH

使其生效 

source /etc/profile

关闭防火墙

systemctl stop firewalld.service

修改端口

sudo vi /usr/local/tomcat/conf/server.xml

将8080改为你想要的端口即可

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <!-- A "Connector" using the shared thread pool-->
    <!--
    <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    -->

配置gui-manager项目部署方式

sudo vi /usr/local/tomcat/conf/tomcat-users.xml

拷贝以下代码放置</tomcat-users>标签之间(注意将password和username换成你自己的)

 <role rolename="manager"/>     
  <role rolename="admin"/> 
  <role rolename="admin-gui"/>
  <role rolename="manager-gui"/>
  <user username="king" password="kingpass" roles="admin-gui,manager-gui"/>

注释标签

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

将Value标签的内容注释

<Context antiResourceLocking="false" privileged="true" >
<!--注释掉此标签
 <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127.d+.d+.d+|::1|0:0:0:0:0:0:0:1" />
-->
</Context>

启动

service tomcat start

如果报错：启动tomcat 报错：Neither the JAVA_HOME nor the JRE_HOME environment variable is defined

关闭

service tomcat stop

访问如下连接即可看到tomcat首页，记得换IP
