问题简述：在oracle linux下安装oracle10g，多个文件报“Permission denied”错误，无法启动图形界面，下面是执行并逐步解决的过程。
[oracle@ocmu software]$ cd database/
[oracle@ocmu database]$ ls
doc install response runInstaller stage welcome.html
[oracle@ocmu database]$
开始执行oracle的安装，忽略对操作系统的认证，报没有权限执行
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs
bash: ./runInstaller: Permission denied
[oracle@ocmu database]$
[oracle@ocmu database]$
检查一下发现确实没有执行权限
[oracle@ocmu database]$ ll
total 28
drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 doc
drwxr-xr-x 5 oracle oinstall 4096 Jul 2 2005 install
drwxr-xr-x 2 oracle oinstall 4096 Jul 2 2005 response
-rw-r–r– 1 oracle oinstall 1327 Jul 2 2005 runInstaller
drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 stage
-rw-r–r– 1 oracle oinstall 5100 Jul 2 2005 welcome.html
授予755 的权限
[oracle@ocmu database]$ chmod 755 runInstaller
[oracle@ocmu database]$ ll
total 28
drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 doc
drwxr-xr-x 5 oracle oinstall 4096 Jul 2 2005 install
drwxr-xr-x 2 oracle oinstall 4096 Jul 2 2005 response
-rwxr-xr-x 1 oracle oinstall 1327 Jul 2 2005 runInstaller
drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 stage
-rw-r–r– 1 oracle oinstall 5100 Jul 2 2005 welcome.html
[oracle@ocmu database]$
再次执行oracle安装，提示/software/database/install/.oui这个隐藏文件没有执行的权限
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs
./runInstaller: line 52: /software/database/install/.oui: Permission denied
cd到指定目录，查看一下，确认没有后，给予755 权限
[oracle@ocmu database]$ cd install/
[oracle@ocmu install]$ ll

回到执行安装目录，三次执行安装，发现有些靠谱了，但是，图形界面还是没有出来，下面还是报错，本次是“/software/database/install/unzip: Permission denied”
[oracle@ocmu install]$ cd ..
[oracle@ocmu database]$
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs

cd到unzip指定目录，赋755

回来，四次执行安装oracle命令，还好，此时，可以正常启动图形界面开始安装了。
[oracle@ocmu install]$ cd ..
[oracle@ocmu database]$
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs
真怕安装到半路还有问题，忐忐忑忑的装成功了。
小结：
为什么那三个文件没有执行权限，它们是怎么导致没有执行权限的呢？
因为，在软件上传到linux服务器之前，由于linux服务器的空间紧张，所以就在windows环境下将其先解压，然后再上传的，上传时，已经是解压后的文件夹了，故导致那三个文件的执行权限丢失。
