启动慢修改如下:

在catalina.sh中加入这么一行:

JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom"

打开$JAVA_PATH/jre/lib/security/java.security这个文件,找到下面的内容:

securerandom.source=file:/dev/urandom

替换成

securerandom.source=file:/dev/./urandom


想登陆管理页面,操作如下:

conf/Catalina/localhost/下创建 manager.xml , 填入如下内容

    
添加用户  conf/tomcat-users.xml 中的 
 标签内添加如下代码:


host-manager 还是 403 错误     解决办法  允许所有IP访问

vim /usr/local/tomcat/webapps/host-manager/META-INF/context.xml
     
 #修改这里

修改成80

vim conf/server.xml

69     <Connector port="80" protocol="HTTP/1.1"

70                connectionTimeout="20000"

71                redirectPort="8443" />


修改默认网页路径

vim conf/server.xml

148       <Host name="localhost"  appBase="webapps"

149             unpackWARs="true" autoDeploy="true">

164 <Context path="" docBase="/usr/local/tomcat/webapps/shyt/" debug="0"/>   ###加入此行, docBase就是你要访问的路径

165       </Host>

修改默认首页文件

vim conf/web.xml        

4693     <welcome-file-list>

4694         <welcome-file>index.html</welcome-file>

4695         <welcome-file>index.htm</welcome-file>

4696         <welcome-file>index.jsp</welcome-file>

4697     </welcome-file-list>
