Tomcat日誌

• ls /usr/local/tomcat/logs
• 其中catalina開頭的日誌爲tomcat的綜合日誌，他記錄tomcat服務相關信息，也會記錄錯誤日誌
• 其中catalina.日期.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server.xml中配置一下

[root@localhost ~]# ls /usr/local/tomcat/logs/

• 具體方法是對應虛擬主機的<Host></Host>裏面加入下面的配置（假如域名爲123.cn）： <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="123.cn_access" suffix=".log" pattern="%h %l %u %t &quot;%r&quot;%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主機的localhost.日期.log日誌，錯誤日誌會統一記錄到catalina.out中。 關於tomcat日誌，最須要關注catalina.out，當出現問題時，應該第一次時間去查看它。
