二、编辑配置文件并保存

          输入vi /etc/ssh/sshd_config，使用vi编辑配置文件；
          使用/Permit快速定位到配置处，#PermitRootLogin yes；
          键入i键，进入编辑模式删除#键，保存退出。
三、重启服务远程登录
          输入/etc/rc/d/init.d/sshd restart，重启sshd服务；
          使用Xshell远程登录服务器，成功。

--------------------Oracle Applications Installation Update Notes, Release 11i (11.5.10.2) (Doc ID 316806.1)
Completing Preinstallation Tasks

Download the patch 6365595 from My Oracle Support.

Follow the Oracle Applications Installation guide and set up the stage area.

Set the STAGE_TOP environment variable to the top level directory of the stage area that contains the subdirectories startCD, oraApps, oraDB, oraiAS and oraAppDB. Make sure that the stage area is read writable.

Create the following directories in the stage area.
mkdir -p /EBS/Stage11i/oraDB/Disk3/db/stage/appsutil/bin
mkdir -p /EBS/Stage11i/oraApps/Disk5/appl/stage/bin

Copy the adgetlnxver.sh file in the patch 6365595 to the following directories created in earlier step.
cp -p /etc/yum.repos.d/wanxin/6365595/ad/bin/adgetlnxver.sh /EBS/Stage11i/oraDB/Disk3/db/stage/appsutil/bin
cp -p /etc/yum.repos.d/wanxin/6365595/ad/bin/adgetlnxver.sh /EBS/Stage11i/oraApps/Disk5/appl/stage/bin

Update the zip archive with the fix (adgetlnxver.sh file).
cd /EBS/Stage11i/oraDB/Disk3/db/stage
zip -u dboh0_appsutil appsutil/bin/adgetlnxver.sh
cd /EBS/Stage11i/oraApps/Disk5/appl/stage
zip -u ad_CORE bin/adgetlnxver.sh

vim /EBS/Stage11i/startCD/Disk1/rapidwiz/bin/runWizard.sh and comment out lines 122-125, as in:
# if test "$exit_code" == "0" ; then  
#   LD_ASSUME_KERNEL=2.4.19  
#   export LD_ASSUME_KERNEL  
# fi

#export LD_ASSUME_KERNEL=2.4.19

--------------------Installation Of Oracle EBS 11.5.10.2 On Oracle Linux Fails (Doc ID 747424.1)
CAUSE
For Oracle Linux 5, Red Hat Enterprise Linux 5 and SUSE Linux Enterprise Server 10, the LD_ASSUME_KERNEL environment variable should be unset before starting the installation. The installation fails when the LD_ASSUME_KERNEL variable is set by the dgetlnxver.sh file during the course of the installation.

SOLUTION
Please apply the following workaround:

1. Edit the <9i RDBMS_ORACLE_HOME>/appsutil/bin/adgetlnxver.sh file as below.
2. Alter by replacing all occurrences of LD_ASSUME_KERNEL with XD_ASSUME_KERNEL.
3. Press the retry button in rapidwiz screen.

unset LD_ASSUME_KERNEL
sed -i 's#LD_ASSUME_KERNEL#XD_ASSUME_KERNEL#g' /EBS/PROD/proddb/9.2.0/appsutil/bin/adgetlnxver.sh

查看SELinux状态：
1、/usr/sbin/sestatus -v      ##如果SELinux status参数为enabled即为开启状态
SELinux status:                 enabled
2、getenforce                 ##也可以用这个命令检查
关闭SELinux：
1、临时关闭（不用重启机器）：
setenforce 0                  ##设置SELinux 成为permissive模式
                              ##setenforce 1 设置SELinux 成为enforcing模式
2、修改配置文件需要重启机器：
修改/etc/selinux/config 文件
将SELINUX=enforcing改为SELINUX=disabled

重启机器即可

/etc/init.d/iptables stop 
chkconfig iptables off
