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

[root@localhost ~]# source /etc/profile  //使修改立即生效
[root@localhost ~]#echo $PATH  //查看PATH值

[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

mysql> set password for 'root'@'localhost' =password('password');
Query OK, 0 rows affected (0.00 sec)
mysql>

Copy after login

Five: Configure mysql

1. Encoding

The mysql configuration file is /etc/my.cnf

Finally, add the encoding configuration

[mysql]
default-character-set =utf8

Copy after login

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

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';
