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

# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server

Restart the mysql service after successful installation.

# service mysqld restart

When installing mysql for the first time, the 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. Encoding

The mysql configuration file is /etc/my.cnf

Finally, add the encoding configuration

[mysql]
default-character-set =utf8

The character encoding here must be consistent with /usr/share/mysql/charsets/Index.xml.

2. Remote connection settings

Assign all permissions on all tables in all databases to the root user located at all IP addresses.

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

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

mysql>create user 'username'@'%' identified by 'password';

Then you can connect remotely.
