新主机克隆ebs后，启动应用没有错误显示status 0，但是主页无法显示，查看apache日志：

在外国的博客中找到如下解决方案：

While starting Apache after clone we faced the following error.

[applmgr@trinity scripts]$ sh adapcctl.sh start
You are running adapcctl.sh version 120.7.12010000.2
Starting OPMN managed Oracle HTTP Server (OHS) instance ...
adapcctl.sh: exiting with status 204
adapcctl.sh: check the

Check the following log file :
/db/VIS/inst/apps/VIS_doyen/logs/ora/10.1.3/opmn/HTTP_Server~1.log

Error :

/db/VIS/inst/apps/VIS_doyen/ora/10.1.3/Apache/Apache/bin/apachectl startssl: execing httpd
/db/VIS/apps/tech_st/10.1.3/Apache/Apache/bin/httpd: error while loading shared libraries: libdb.so.2: cannot open shared object file: No such file or directory

Cause:

http web server unable to start due to missing library.

Solution:

Create link for library file as below

ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2

Now start Apache and check the same.

[applmgr@DOYEN scripts]$ sh adapcctl.sh start
You are running adapcctl.sh version 120.7.12010000.2
Starting OPMN managed Oracle HTTP Server (OHS) instance ...
adapcctl.sh: exiting with status 0

Now you should be able to access the application.

解决思路：
无法访问很多情况下是apache的问题，大家一定要记住，解决问题一定要看日志！！
希望大家多一些原创内容，多做一些研究，不要让我们为了解决这点小问题还要去翻墙找外国人的博客。
