touch: cannot touch `/usr/local/tomcat702/logs/catalina.out’: Permission denied
问题描述：
logs目录没有创建修改权限

./startup.sh
Using CATALINA_BASE: /usr/local/tomcat702
Using CATALINA_HOME: /usr/local/tomcat702
Using CATALINA_TMPDIR: /usr/local/tomcat702/temp
Using JRE_HOME: /usr/java/jdk1.6.0_24
Using CLASSPATH: /usr/local/tomcat702/bin/bootstrap.jar:/usr/local/tomcat702/bin/tomcat-juli.jar
touch: cannot touch `/usr/local/tomcat702/logs/catalina.out’: Permission denied

解决办法：
所有人可操作logs文件。
chmod说明(u:与文件属主拥有一样的权限[a:所有人]；+:增加权限;rwx:可读可写可执行）
-R:递归所有目录和文件

cd /usr/local/tomcat
sudo chmod a+rwx -R logs
