卸载

[root@wangchao src]# which java

/usr/bin/java

[root@wangchao src]# rpm -qf /usr/bin/java

file /usr/bin/java is not owned by any package

[root@wangchao src]# yum list |grep jdk

[root@wangchao tomcat]# cp -v bin/catalina.sh /etc/init.d/tomcat

[root@wangchao tomcat]# chmod 755 /etc/init.d/tomcat

root@wangchao tomcat]# chkconfig --add tomcat

service tomcat does not support chkconfig              //报错不支持

 

 

[root@wangchao tomcat]# vim /etc/init.d/tomcat                    //从第二行加入

windows访问192.168.137.22:8080.出现tomcat默认页面

 

 

 

 

tomcat的优化

 

[root@wangchao tomcat]# cd /usr/local/tomcat/conf/

[root@wangchao conf]# ls

[root@wangchao conf]# vim server.xml

将<Connector port="8080" protocol="HTTP/1.1"中的8080改成80

//插入：

<Host name="www.123.com" appBase="/data/tomcatweb"

                 unpackWARs="false" autoDeploy="true" xmlValidation="false"

                 xmlNamespaceAware="false">

                <Context path="" docBase="./" debug="0" reloadable="true" crossContext="true"/>

      </Host>

 

[root@wangchao conf]# mkdir -p /data/tomcatweb

[root@wangchao conf]# /etc/init.d/tomcat stop

[root@wangchao conf]# /etc/init.d/tomcat start

[root@wangchao conf]# ps aux |grep java

客户端访问192.168.137.22无需再加8080
