1. apt-get update

2. 修改源 vi /etc/apt/sources.list
   阿里源：
   deb-src http://archive.ubuntu.com/ubuntu xenial main restricted #Added by software-properties
   deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted
   deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted multiverse universe #Added by software-properties
   deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted
   deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted multiverse universe #Added by software-properties
   deb http://mirrors.aliyun.com/ubuntu/ xenial universe
   deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
   deb http://mirrors.aliyun.com/ubuntu/ xenial multiverse
   deb http://mirrors.aliyun.com/ubuntu/ xenial-updates multiverse
   deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
   deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse #Added by software-properties
   deb http://archive.canonical.com/ubuntu xenial partner
   deb-src http://archive.canonical.com/ubuntu xenial partner
   deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted
   deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted multiverse universe #Added by software-properties
   deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
   deb http://mirrors.aliyun.com/ubuntu/ xenial-security multiverse
   apt-get update

3. 安装jdk
   sudo apt-get install openjdk-8-jdk
   java -version 测试

4. 安装tomcat
   cd /opt
   wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.35/bin/apache-tomcat-8.5.35.tar.gz
   wget https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.30/bin/apache-tomcat-8.5.30.tar.gz
   tar zxvf apache-tomcat-8.5.35.tar.gz
   设置角色
   sudo vim /opt/tomcat8/conf/tomcat-users.xml

   再tomcat8开始, 只修改tomcat-users还是会出现403, 禁止访问.

   原因是tomcat8开始, 默认只能本机访问管理项目, 再host-manager和manager项目下的/META-INF/下有个context.xml

   里面默认启用了访问控制:

   注释掉可以了

5. 安全端口设置
   tcpdump tcp port 80 查看端口的流量

6. 配置https

7. 配置dns

8. maven的配置

   org.apache.tomcat.maven
   tomcat7-maven-plugin
   2.2

   tomcat7
   /
   http://114.116.85.172:80/manager/text
   username
   password

9. 配置nginx
   apt-get install nginx
   Ubuntu安装之后的文件结构大致为：

   所有的配置文件都在/etc/nginx下，并且每个虚拟主机已经安排在了/etc/nginx/sites-available下
   程序文件在/usr/sbin/nginx
   日志放在了/var/log/nginx中
   并已经在/etc/init.d/下创建了启动脚本nginx
   默认的虚拟主机的目录设置在了/var/www/nginx-default (有的版本 默认的虚拟主机的目录设置在了/var/www, 请参考/etc/nginx/sites-available里的配置)
   upstream book_pool{
   server 127.0.0.1:9000;
   }

   server {
   listen 80;
   server_name 114.116.85.172;
   access_log logs/blog.log;
   error_log logs/blog.error;

    #将所有请求转发给demo_pool池的应用处理
    location / {
    	proxy_set_header Host $host;
    	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    	proxy_pass http://book_pool;
    }
   

   }

   最后 nginx -s reload

10. tomcat-user.xml 的配置

    <role rolename="manager-gui"/>
    <role rolename="manager-script"/>

    <user username="xjtu" password="xjtu28xjtu28xjtu" roles="manager-gui,manager-script"/>

9. tomcat的server.xml配置

<Resource name="UserDatabase" auth="Container"
          type="org.apache.catalina.UserDatabase"
          description="User database that can be updated and saved"
          factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
          pathname="conf/tomcat-users.xml" />

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

<Engine name="Catalina" defaultHost="localhost">

  <Realm className="org.apache.catalina.realm.LockOutRealm">
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
           resourceName="UserDatabase"/>
  </Realm>

9. springboot的启动
   nohup java -jar ./xxxx.jar > ./xxxx.log 2>&1 &
