Tomcat介绍
Tomcat 服务器是一个免费的开放源代码的Web 应用服务器,是开发和调试JSP 程序的首选。
实际上Tomcat是Apache 服务器的扩展，但运行时它是独立运行的，所以当你运行tomcat 时，它实际上作为一个与Apache 独立的进程单独运行的.

部署Tomcat
- 配置JAVA环境(JDK)
# 安装JDK环境
[root@localhost ~]# yum install -y java-1.8.0-openjdk*
......
Complete!
- 下载解压tomcat
[root@localhost src]# wget https://archive.apache.org/dist/tomcat/tomcat-10/v10.0.0-M10/bin/apache-tomcat-10.0.0-M10.tar.gz

- 开启tomcat服务
[root@localhost webapps]# /usr/local/tomcat/bin/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
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Tomcat started.

解决方案
[root@localhost webapps]# vim usr/local/tomcat/conf/tomcat-users.xml
......
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="123456" roles="admin-gui,manager-gui"/>
</tomcat-users>
##文件尾部添加角色名及用户密码
## 在manager/context文件中添加本机ip
[root@localhost manager]# vim META-INF/context.xml
......
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="192.168.197.d+|127.d+.d+.d+|::1|0:0:0:0:0:0:0:1" /> ## 在allow中添加本网段地址
## 同理，添加host-manager配置文件中Ip
[root@localhost local]# vim tomcat/webapps/host-manager/META-INF/context.xml
......
<Valve className="org.apache.catalina.valves.RemoteAddrValve"
allow="192.168.197.d+|127.d+.d+.d+|::1|0:0:0:0:0:0:0:1" />
......
## 重启服务
[root@localhost local]# /usr/local/tomcat/bin/catalina.sh stop;/usr/local/tomcat/bin/catalina.sh start
......
Tomcat started.
