Editor to share with you in the installation of JDK1.7 in Linux RedHat5.5 installation problems Error: dl failure on line 864 how to do, I believe most people do not know much, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Problem description: the JDK1.7 installed in Linux RedHat5.5, and by modifying the JAVA_HOME in the profile file, it is found that the java-version command still displays version 1.4. analysis of the reason shows that the system does not execute the java command according to the settings of profile, but runs through the JDK program that comes with the system under / usr/java. In desperation, delete all files under / usr/java through the rm-rf command, and then run the java command again. The following problems have occurred:

Error: dl failure on line 864Error: failed / home/app/jdk1.7.0_21/jre/lib/i386/client/libjvm.so, because / home/app/jdk1.7.0_21/jre/lib/i386/client/libjvm.so: cannot restore segment prot after reloc: Permission denied

Analysis results: the final Permission denied shows that the security of the system blocks the execution of some actions by java. So check the system firewall iptables, has been turned off, so I think of Selinux

There are two solutions:

1. Enter directly: / usr/sbin/setenforce 0 means to turn off SELINUX, but this is only a session-level setting

2. Global settings disable SELINUX, edit / etc/sysconfig/selinux file, change the SELINUX parameter to disabled, and then restart it.
