CentOS配置Tomcat監聽80端口,虛擬主機

Tomcat更改默認端口爲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"修改成Connector port="80" 
[root@test-a ~]#
[root@test-a ~]# netstat -ntlp | grep 80

CentOS經過Tomcat安裝zrlog博客系統

• vim /usr/local/tomcat/conf/server.xml
  其中<Host>和</Host>之間的配置爲虛擬主機配置部分，name定義域名， appBase定義應用的目錄，Java的應用一般是一個war的壓縮包，只須要將war的壓縮包放到appBase目錄下面便可

Tomcat配置虛擬主機

• vim /usr/local/tomcat/conf/server.xml
  其中<Host>和</Host>之間的配置爲虛擬主機配置部分，name定義域名， appBase定義應用的目錄，Java的應用一般是一個war的壓縮包，只須要將war的壓縮包放到appBase目錄下面便可

• 增長虛擬主機，編輯server.xml,在</Host>下面增長以下內容
  <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，這個參數用來定義網站的文件存放路徑，若是不定義，默認是在appBase/ROOT下面，定義了docBase就以該目錄爲主了，其中appBase和docBase能夠同樣。
  appBase爲應用存放目錄，一般是須要把war包直接放到該目錄下面，它會自動解壓成一個程序目錄

[root@test-a src]# vim /usr/local/tomcat/conf/server.xml # 添加虛擬主機配置
[root@test-a ~]# mkdir /data/wwwroot/666.cn # 建立新站目錄
[root@test-a ~]# mv /usr/local/tomcat/webapps/zrlog/* /data/wwwroot/666.cn/ # 把以前安裝的zrlog全部文件移到虛擬站點
# 從新啓動
[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

Tomcat started.

修改hosts指定www.666.cn的ip爲192.168.77.134後訪問:

Tomcat 日誌

• 路徑 /usr/local/tomcat/logs
• 其中catalina開頭的日誌爲Tomcat的綜合日誌，它記錄Tomcat服務相關信息，也會記錄錯誤日誌。
• catalina.2017-xx-xx.log和catalina.out內容相同，前者會天天生成一個新的日誌。
• host-manager和manager爲管理相關的日誌，其中host-manager爲虛擬主機的管理日誌。
• localhost和localhost_access爲虛擬主機相關日誌，其中帶access字樣的日誌爲訪問日誌，不帶access字樣的爲默認虛擬主機的錯誤日誌。
• 訪問日誌默認不會生成，須要在server.xml中配置一下。
• 具體方法是在對應虛擬主機的<Host></Host>裏面加入下面的配置（假如域名爲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定義訪問日誌的前綴，suffix定義日誌的後綴，pattern定義日誌格式。新增長的虛擬主機默認並不會生成相似默認虛擬主機的那個localhost.日期.log日誌，錯誤日誌會統一記錄到catalina.out中。關於Tomcat日誌你最須要關注catalina.out，當出現問題時，應該第一想到去查看它。
