4. Disable selinux.

[Root @ wangmaster yum. repos. d] # vim/etc/selinux/config

# This file controls the state of SELinux on the system.

# SELINUX = can take one of these three values:

# Enforcing-SELinux security policy is enforced.

# Permissive-SELinux prints warnings instead of enforcing.

# Disabled-No SELinux policy is loaded.

SELINUX = disabled

# SELINUXTYPE = can take one of three two values:

# Minimum-Modification of targeted policy. Only selected processes are protected.

# Mls-Multi Level Security protection.

SELINUXTYPE = targeted

 

5. Stop the Firewall

Query the Firewall Status:
[Root @ localhost ~] # Service iptables status
Stop Firewall:
[Root @ localhost ~] # Service iptables stop
Start Firewall:
[Root @ localhost ~] # Service iptables start
Restart Firewall:
[Root @ localhost ~] # Service iptables restart
Permanently disable the Firewall:
[Root @ localhost ~] # Chkconfig iptables off
Enable after permanent shutdown:
[Root @ localhost ~] # Chkconfig iptables on

 

6. Install the JDK Environment

Tar-zxvf jdk1.8.tar.gz

Modify the/etc/profile file and configure the java environment

Vim/etc/profile

JAVA_HOME =/usr/local/java/jdk1.8

JAVA_BIN =/usr/local/java/jdk1.8/bin

PATH = $ PATH: $ JAVA_HOME/bin

CLASSPATH =.: $ JAVA_HOME/lib/dt. jar: $ JAVA_HOME/lib/tools. jar: $ JAVA_HOME/jre/lib/rt. jar

Export JAVA_HOME

Export JAVA_BIN

Export PATH

Export CLASSPATH

Iii. Problems during installation (1) the virtualization performance counters are incompatible with binary conversions.

 

 

Solution: Disable the performance counter when setting the processor.

(2) failed to obtain the GPG key in linux

Solution:

The major problem is that your system does not have the yum GPG key.

• View your system version
• Cat/etc/issue
• Log onto mirrors.163.com and find the key of your system.
• RPM-GPG-KEY-CentOS-3
• RPM-GPG-KEY-CentOS-4
• RPM-GPG-KEY-CentOS-5
• RPM-GPG-KEY-CentOS-6
• Use command rpm -- import to import
• Rpm -- import http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6 (Change 6 to your current version)
• Use the yum-y install tree.
