tomcat优化

tomcat优化

进入到/tomcat/bin/conf/server.原<Connector port="8080" protocol="HTTP/1.1"                  connectionTimeout="20000" 

原<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="84

改<Connector port="8080"
protocol="org.apache.coyote.http11.Http11AprProtocol"
maxThreads="500"
minSpareThreads="100"
enableLookups="false"
redirectPort="8443"
acceptCount="500"
connectionTimeout="20000"
disableUploadTimeout="true"
URIEncoding="UTF-8"
server="Guess"
maxSpareThreads="500"
minProcessors="100"
maxProcessors="500" />
末尾默认是注销掉，把注销去掉
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="/data/tomcat-1-logs/"
prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>  ---------指定tomcat日志路径

需要把以下的包装上

/usr/local/tomcat-1/bin
tar -zxvf tomcat-native.tar.gz
cd tomcat-native-1.1.34-src/jni/native
都在/data下
yum -y install apr apr-devel gcc openssl openssl-devel
./configure --with-apr=/usr/bin/apr-1-config && make && make install

　　

在开发/测试环境，日志是非常重要的。而公司对于测试环境进行了控制，只有配置人员能连接访问，而开发人员是无法获取该服务器的信息的。在出现错误时，没有异常日志，开发是很难重现问题的。因此需要对中间件 tomcat 进行配置，将日志放到某个目录下，开发人员可以通过浏览器就能查看日志。ok，开工：

目的： 能通过浏览器检查tomcat日志

方法：将 tomcat 的日志放置到 $CATALINA_HOME/webapps/ROOT/logs 下，用户就可以通过 http://xxx.xxx.xxx.xxx/logs/catalina.out 访问日志了。

1. 修改tomcat/conf下的logging.properties

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

1catalina.org.apache.juli.FileHandler.level = FINE

1catalina.org.apache.juli.FileHandler.prefix = catalina.

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler

# For example, to log debug messages in ContextConfig and HostConfig
# classes and to log only warnings and errors in other
# org.apache.catalina.** classes, uncomment these lines:
#org.apache.catalina.startup.ContextConfig.level = FINE
#org.apache.catalina.startup.HostConfig.level = FINE
#org.apache.catalina.level = WARNING

2. 修改tomcat/bin/catalina.sh 

1 2 3

186 if [ -z "$CATALINA_OUT" ] ; then 187   CATALINA_OUT=<strong><span style="color: #ff0000;">"$CATALINA_BASE"/webapps/ROOT/logs/catalina.out</span></strong> 188 fi

3　在server.xml里修改最后一行修改红色字的地方

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="/data/tomcat-1-logs/" 
prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>  ---------指定tomcat日志路径

　　

【注意】红色字体是需要修改的内容，修改为当前 tomcat 的最新的网站根目录即可。

4、重启 tomcat

5、使用浏览器即可查看日志： http://xxx.xxx.xxx.xxxx/logs/catalina.out
