CentOS配置Tomcat监听80端口,虚拟主机

Tomcat更改默认端口为80

更改的配置文件是: /usr/local/tomcat/conf/server.xml

[root@test-a ~]# vim /usr/local/tomcat/conf/server.xml  # 找到 Connector port="8080" protocol="HTTP/1.1"修改为Connector port="80" 
[root@test-a ~]#
[root@test-a ~]# netstat -ntlp | grep 80

[root@test-a ~]# /etc/init.d/nginx stop

[root@test-a ~]#
[root@test-a ~]# netstat -ntlp | grep 80

[root@test-a ~]# /usr/local/tomcat/bin/startup.sh

CentOS通过Tomcat安装zrlog博客系统

• vim /usr/local/tomcat/conf/server.xml
  其中<Host>和</Host>之间的配置为虚拟主机配置部分，name定义域名， appBase定义应用的目录，Java的应用通常是一个war的压缩包，只需要将war的压缩包放到appBase目录下面即可

Tomcat配置虚拟主机

• vim /usr/local/tomcat/conf/server.xml
  其中<Host>和</Host>之间的配置为虚拟主机配置部分，name定义域名， appBase定义应用的目录，Java的应用通常是一个war的压缩包，只需要将war的压缩包放到appBase目录下面即可

• 增加虚拟主机，编辑server.xml,在</Host>下面增加如下内容
  <Host name="www.666.cn" appBase="" unpackWARs= "true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
  <Context path="" docBase="/data/wwwroot/666.cn/" debug="0" reloadable="true" crossContext="true"/>

</Host>

• docBase，这个参数用来定义网站的文件存放路径，如果不定义，默认是在appBase/ROOT下面，定义了docBase就以该目录为主了，其中appBase和docBase可以一样。
  appBase为应用存放目录，通常是需要把war包直接放到该目录下面，它会自动解压成一个程序目录

[root@test-a src]# vim /usr/local/tomcat/conf/server.xml # 添加虚拟主机配置
[root@test-a ~]# mkdir /data/wwwroot/666.cn # 创建新站目录
[root@test-a ~]# mv /usr/local/tomcat/webapps/zrlog/* /data/wwwroot/666.cn/ # 把之前安装的zrlog所有文件移到虚拟站点
# 重新启动
[root@test-a src]# /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@test-a src]# /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.

修改hosts指定www.666.cn的ip为192.168.77.134后访问:

Tomcat 日志

• 路径 /usr/local/tomcat/logs
• 其中catalina开头的日志为Tomcat的综合日志，它记录Tomcat服务相关信息，也会记录错误日志。
• catalina.2017-xx-xx.log和catalina.out内容相同，前者会每天生成一个新的日志。
• host-manager和manager为管理相关的日志，其中host-manager为虚拟主机的管理日志。
• localhost和localhost_access为虚拟主机相关日志，其中带access字样的日志为访问日志，不带access字样的为默认虚拟主机的错误日志。
• 访问日志默认不会生成，需要在server.xml中配置一下。
• 具体方法是在对应虚拟主机的<Host></Host>里面加入下面的配置（假如域名为666.cn）：

• <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="666.cn_access" suffix=".log" pattern="%h %l %u %t %r %s %b" />

• prefix定义访问日志的前缀，suffix定义日志的后缀，pattern定义日志格式。新增加的虚拟主机默认并不会生成类似默认虚拟主机的那个localhost.日期.log日志，错误日志会统一记录到catalina.out中。关于Tomcat日志你最需要关注catalina.out，当出现问题时，应该第一想到去查看它。
