配置Tomcat监听80端口

修改tomcat的默认端口，将其改为80端口，在Connector port端口指定的地方修改为80端口，wq保存退出

[root@aaa ~]# vim /usr/local/tomcat/conf/server.xml <Connector port="80" protocol="HTTP/1.1"connectionTimeout="20000"redirectPort="8443" />

关闭其他web服务，如nginx的服务，以免出现占用端口

[root@aaa ~]# /etc/init.d/nginx stop
Stopping nginx (via systemctl): [ 确定 ]

重新启动tomcat服务，tomcat没有nginx类似的服务启动重启脚本，只能将服务先停止然后再启动

[root@aaa ~]# /usr/local/tomcat/bin/shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/jdk1.8
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@aaa ~]# /usr/local/tomcat/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/jdk1.8
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

查看tomcat的端口占用，8005端口是tomcat服务的管理端口，只有在这个端口启动监听后tomcat才能够正常提供访问

[root@aaa ~]# netstat -ntlp |grep 80
tcp6 0 0 :::80 :::* LISTEN 19270/java
tcp6 0 0 127.0.0.1:8005 :::* LISTEN 19270/java
tcp6 0 0 :::8009 :::* LISTEN 19270/java
```
测试通过80端口访问tomcat，curl不指定端口默认会是80端口

[root@aaa ~]# curl -I 192.168.1.234
HTTP/1.1 200

# tomcat虚拟主机添加tomcat虚拟主机
编辑tomcat的server.xml配置文件，添加一个虚拟主机配置

[root@aaa ~]# vim /usr/local/tomcat/conf/server.xml
<Host name="www.abc.com" appBase=""
           unpackWARs="true" autoDeplo="true"
           xmlValidation="false" xmlNamespaceAware="false">
      <Context path="" docBase="/data/wwwroot/abc/" debug="0"
          reloadable="true" crossContext="true"/>
    </Host>

server的虚拟主机配置说明
在<Host></Host>这个标签中定义tomcat的虚拟主机，其中docBase和appBase来定义网站文件的存放路径，如果不定义docBase，则默认会认为网站文件存放在appBase/ROOT目录下，如果定义了docBase，则就会以docBase定义的目录为主了，生效的是docBase中定义的目录，如果这步没有定义正确则会遇到404的访问问题
appBase是存放应用的目录，通常是把war包放在该目录下，tomcat会自动解压出一个程序目录出来使用tomcat部署一个博客项目
首先下载项目的war包，拷贝war包到/usr/local/tomcat/webapps目录当中，让tomcat自动解压出文件目录，把解压的目录改为其他名字。之后删除war包，如下操作

[root@aaa webapps]# cp /usr/local/src/zrlog-2.0.2-5ebb1f3-release.war .
[root@aaa webapps]# ls
docs examples host-manager manager ROOT zrlog-2.0.2-5ebb1f3-release.war
[root@aaa webapps]# mv zrlog-2.0.2-5ebb1f3-release zrlog
[root@aaa webapps]# rm -rf zrlog-2.0.2-5ebb1f3-release.war
[root@aaa webapps]# ls
docs examples host-manager manager ROOT zrlog

之后访问192.168.1.234/zrlog的安装页面，192.168.1.234是服务器本机ip地址
安装界面如下![](https://s1.51cto.com/images/blog/201808/30/2bd86ede47b4a7e4769939df065f6cdb.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
这里我们需要为zrlog创建名字为zrlog存储数据的数据库，并需要创建zrlog库并给予一定的权限，使用测试用户zrlog登录并验证数据库用户正确性

mysql> create database zrlog;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on zrlog.* to 'zrlog'@127.0.0.1 identified by 'P@123' ;
Query OK, 0 rows affected, 1 warning (0.01 sec)
[root@aaa webapps]# mysql -uzrlog -h127.0.0.1 -p
Enter password:

创建后按提示写入连接数据库的用户和密码进行下一步操作
安装后进入的管理控制页面
![](https://s1.51cto.com/images/blog/201808/30/279adb904f5238af3a6c11d7aa43335a.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)将web文件目录移动位置，使用定义的域名进行访问，这里将zrlog目录下所有的文件拷贝或移动到指定的网站文件目录下，注意不是拷贝zrlog本身，这和指定的网站目录路径有关

[root@aaa webapps]# ls
docs examples host-manager manager ROOT zrlog
[root@aaa webapps]# cd /data/wwwroot/abc/
[root@aaa abc]# cp -rf /usr/local/tomcat/webapps/zrlog/* .
[root@aaa abc]# ls
admin assets error favicon.ico include META-INF WEB-INF
[root@aaa abc]# pwd
/data/wwwroot/abc

重新启动tomcat，使server.xml中的配置生效

[root@aaa abc]# /usr/local/tomcat/bin/shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/jdk1.8
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@aaa abc]# /usr/local/tomcat/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/local/jdk1.8
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

查看tomcat启动的端口，tomcat只监听80、8009和8005端口，其他端口则是由网站程序监听的

[root@aaa abc]# netstat -ntlp |grep java
tcp6 0 0 127.0.0.1:45711 ::: LISTEN 20309/java          
tcp6 0 0 127.0.0.1:25711 ::: LISTEN 20309/java          
tcp6 0 0 :::80 ::: LISTEN 20254/java          
tcp6 0 0 127.0.0.1:53080 ::: LISTEN 20276/java          
tcp6 0 0 127.0.0.1:55711 ::: LISTEN 20309/java          
tcp6 0 0 127.0.0.1:8005 ::: LISTEN 20254/java          
tcp6 0 0 127.0.0.1:43080 ::: LISTEN 20276/java          
tcp6 0 0 127.0.0.1:23080 ::: LISTEN 20276/java          
tcp6 0 0 :::8009 :::* LISTEN 20254/java

在定义的配置中，Host name是定义的域名，docBase定义的是网站存储的目录，appBase是存储应用的默认目录，如果设置了docBase，则appBase不需要配置

<Host name="www.aaa.com" appBase=""
           unpackWARs="true" autoDeplo="true"
           xmlValidation="false" xmlNamespaceAware="false">
      <Context path="" docBase="/data/wwwroot/abc/" debug="0"
          reloadable="true" crossContext="true"/>
    </Host>

在windows的host中写入测试解析的主机，在浏览器中访问定义的域名，查看是否能直接通过域名进行访问为了防止浏览器反馈给我们缓存的页面，需要使用ctrl+F5来进行强制刷新请求，返回访问结果![](https://s1.51cto.com/images/blog/201808/30/3c852a5aa558e1219236bf5bde6d2d7a.png?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
