我在linux下的MyEcpLise配置类tomcat7,但是启动时却显示：
二月 21, 2015 12:38:08 下午 org.apache.catalina.startup.Catalina load
警告: Unable to load server configuration from [/opt/tomcat7.0/conf/server.xml]
二月 21, 2015 12:38:08 下午 org.apache.catalina.startup.Catalina load
警告: Permissions incorrect, read permission is not allowed on the file.

二月 21, 2015 12:38:08 下午 org.apache.catalina.startup.Catalina start
严重: Cannot start server. Server instance is not configured.
而且在终端中输入 ./startup.sh 却显示：
Using CATALINA_BASE: /opt/tomcat7.0
Using CATALINA_HOME: /opt/tomcat7.0
Using CATALINA_TMPDIR: /opt/tomcat7.0/temp
Using JRE_HOME: /opt/jdk/jdk1.8
Using CLASSPATH: /opt/tomcat7.0/bin/bootstrap.jar:/opt/tomcat7.0/bin/tomcat-juli.jar
touch: 无法创建"/opt/tomcat7.0/logs/catalina.out": 权限不够
./catalina.sh: 385: ./catalina.sh: cannot create /opt/tomcat7.0/logs/catalina.out: Permission denied
本人也在 /etc/profile中设置了环境变量：
#set tomcat7.0
TOMCAT_HOME=/opt/tomcat7.0
export TOMCAT_HOME
jdk也设置的没有问题，我是linux菜鸟，请教大神帮我解决！！！
文件属性不对。你没法访问。
用chmod修改一下文件属性。
麻烦详细说下可以吗？我刚才把tomcat复制到了非root用户的文件下，现在可以以非用户身份运行startup.sh，但是使用shutdown.sh时却显示：
Using CATALINA_BASE: /home/snow/soft/tomcat7.0
Using CATALINA_HOME: /home/snow/soft/tomcat7.0
Using CATALINA_TMPDIR: /home/snow/soft/tomcat7.0/temp
Using JRE_HOME: /opt/jdk/jdk1.8
Using CLASSPATH: /home/snow/soft/tomcat7.0/bin/bootstrap.jar:/home/snow/soft/tomcat7.0/bin/tomcat-juli.jar
二月 21, 2015 3:17:21 下午 org.apache.catalina.startup.Catalina stopServer
严重: Catalina.stop:

并且myeclipse运行tomcat时还是显示：

文件属性，可执行可读可写，具体百度一下。记不清了
