This article mainly introduces the centos7.2.1511 system installation jdk1.8.0_151 tutorial parsing, the content of the article is the author carefully selected and edited, based on the centos7.2.1511 system installation jdk1.8.0_151 tutorial parsing has a certain pertinence, for everyone's reference significance or greater, the following with the author to understand the next topic content.

One: environment

Second: download the rpm package of jdk locally and upload it to the CVM (because I just started to use wget to download directly to the CVM, and the installation keeps reporting errors, so I decided to use this stupid method)

Download address: http://download.oracle.com/otn-pub/java/jdk/8u151-b12/e758a0de34e24606bca991d704f6dcbf/jdk-8u151-linux-x64.rpm

JDK is installed in / usr/java by default

Three: configure environment variables

My machine can perform java-version operations normally without configuring environment variables after installing jdk-8u151-linux-x64.rpm, so I did not configure JDK environment variables. However, for future discomfort, here is a record of how to configure it, as follows:

Modify the system environment variable file

Vi / etc/profile

Append the following to the file:

JAVA_HOME=/usr/java/jdk1.8.0_151

JRE_HOME=/usr/java/jdk1.8.0_151/jre

PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/libexport JAVA_HOME JRE_HOME PATH CLASSPATH

Make the changes effective

[root@localhost ~] # source / etc/profile / / make the changes effective immediately

[root@localhost ~] # echo $PATH / / View path value

View the status of the system environment

[root@localhost ~] # echo $PATH

/ usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/java/jdk1.8.0_25/bin:/usr/java/jdk1.8.0_25/jre/bin

4: install mysql (download and install mysql-server on the official website)

# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

# rpm-ivh mysql-community-release-el7-5.noarch.rpm

# yum install mysql-community-server

Restart the mysql service after successful installation.

# service mysqld restart

The initial installation of the mysql,root account does not have a password.

Set password

Mysql > set password for 'root'@'localhost' = password (' password')

Query OK, 0 rows affected (0.00 sec)

Mysql >

Five: configure mysql

1. Coding

The mysql configuration file is / etc/my.cnf

Finally, add the coding configuration.

[mysql]

Default-character-set = utf8

The character encoding here must be the same as in / usr/share/mysql/charsets/Index.xml.

2. Remote connection settings

Assign all permissions on all tables in all databases to root users at all IP addresses.

Mysql > grant all privileges on *. * to root@'%'identified by 'password'

If it is a new user instead of root, create a new user first

Mysql > create user 'username'@'%' identified by' password'

At this point, you can connect remotely.
