CentOS 6.3 minimal install problems

Problem: Booted and only lo interface was enabled.

Solution: Edit the /etc/sysconfig/network-scripts/ifcfg-eth0 and change the following line:




and reboot. Probably a network restart would suffice.

Problem: Root exception is java.lang.ClassNotFoundException: org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory in Tomcat 6

Solution: tomcat-dbcp.jar is not included on the tomcat6 package on yum. Download it from here or copy it from another Tomcat 6 install (copy it to /usr/share/tomcat6/lib).

Problem: Commands not present in /usr/bin or /usr/sbin don’t seem to work, even when you have changed to the command’s directory


I don’t know if it happens with all commands, but happened to the “keytool” utility within the Oracle JDK directory. At the prompt I would type:

$ keytool

And it would not work, I double checked that I has cd’ed to the directory where keytool was (an ls -l would show it). Then, I remembered that I used to have to type it like this on some Linux installs:

$ ./keytool

And it worked!!
