tomcat是随机启动的，所以在开启服务器的时候要手动开启tomcat，不然没法访问（网上说可以设置随着服务器开启而开启，我还不会妮。。。）

1：找到tomcat安装路径
[root@localhost ~]# cd .. （返回上一级目录）
[root@localhost /]# ls ?????? （列出该目录下的所有文件）
bin?? dev? home? lib64?????? media? mnt? opt?? root? selinux? sys?????? tmp? var
boot? etc? lib?? lost+found? misc?? net? proc? sbin? srv????? tftpboot? usr
[root@localhost /]# cd var ? （打开var这个文件夹）
[root@localhost var]# ls ??? （查看该文件的列表）
account?? crash? empty? gdm?????? local? mail?? opt?????? run??? tux
arpwatch? cvs??? ftp??? kerberos? lock?? named? preserve? spool? www
cache???? db???? games? lib?????? log??? nis??? racoon??? tmp??? yp
（看来不在var文件夹中，只能返回上一级目录）
[root@localhost var]# cd ..
[root@localhost /]# cd usr
[root@localhost usr]# ls
2.sql???????????????????? etc????? java????? lib64??? sbin?? tmp
apache-tomcat-7.0.14.tar? games??? kerberos? libexec? share? tomcat7.0
bin?????????????????????? include? lib?????? local??? src??? X11R6
[root@localhost usr]# cd tomcat7.0 ? （打开tomcat7.0这个文件夹）
[root@localhost tomcat7.0]# ls
bin ?? hsperfdata_root? LICENSE? NOTICE???????? RUNNING.txt? webapps
conf? lib????????????? logs???? RELEASE-NOTES? temp???????? work
[root@localhost tomcat7.0]# cd bin
[root@localhost bin]# ls
bootstrap.jar???????????????? configtest.sh???? setclasspath.sh? tomcat-native.tar.gz
catalina.bat????????????????? cpappend.bat????? shutdown.bat???? tool-wrapper.bat
catalina.sh?????????????????? d:??????????????? shutdown.sh????? tool-wrapper.sh
catalina-tasks.xml??????????? digest.bat??????? startup.bat????? version.bat
commons-daemon.jar??????????? digest.sh???????? startup.sh?????? version.sh
commons-daemon-native.tar.gz? setclasspath.bat? tomcat-juli.jar
[root@localhost bin]# ./ （当前目录，这里是做什么用的，不太清楚。。。）
-bash: ./: is a directory
[root@localhost bin]# ./startup.sh ???? （启动Tomcat）
Using CATALINA_BASE:?? /usr/tomcat7.0
Using CATALINA_HOME:?? /usr/tomcat7.0
Using CATALINA_TMPDIR: /usr/tomcat7.0
Using JRE_HOME:??????? /usr/java/jdk1.6.0_24
Using CLASSPATH:?????? /usr/tomcat7.0/bin/bootstrap.jar:/usr/tomcat7.0/bin/tomcat-juli.jar

启动成功

2：查看tomcat的日志
[root@localhost bin]# cd ..
[root@localhost tomcat7.0]# ls
bin?? hsperfdata_root? LICENSE? NOTICE???????? RUNNING.txt? webapps
conf? lib????????????? logs ???? RELEASE-NOTES? temp???????? work
[root@localhost tomcat7.0]# cd logs? (打开日志文件夹)
[root@localhost logs]# ls
catalina.2011-05-30.log????? localhost.2011-06-28.log
catalina.out???????????????? localhost_access_log.2011-06-27.txt
host-manager.2011-05-30.log? localhost_access_log.2011-07-07.txt
（没用的不贴了）
[root@localhost logs]# tail -f catalina.out ? （查看tomcat的日志文件）
