--1、创建用户组mysql，创建用户mysql并将其添加到用户组mysql中，并赋予读写权限

groupadd mysql                   --创建mysql用户组组

useradd -r -g mysql mysql     --创建mysql用户并添加到mysql用户组中

chown -R mysql mysql/         --将mysql目录访问权限赋为myql用户

chgrp -R mysql mysql/          --改变mysql目录的用户组属于mysql组

--2、创建安装目录

mkdir -p /oracle/app/mysql/data

chown -R mysql.mysql /oracle/app/mysql

--3、上传MySQL文件并进行解压

cd /oracle/app/mysql

mv /software/V974639-01.zip  .

unzip V974639-01.zip

tar zxf mysql-advanced-5.7.21-el7-x86_64.tar.gz

--4、创建配置文件,保存并退出

vim /etc/my.cnf

[client]

port = 3307

socket = /oracle/app/mysql/data/mysql.sock

[mysqld]

character_set_server=utf8

init_connect='SET NAMES utf8'

basedir=/oracle/app/mysql

datadir=/oracle/app/mysql/data

socket=/oracle/app/mysql/data/mysql.sock

log-error=/var/log/mysqld.log

pid-file=/var/run/mysqld/mysqld.pid

lower_case_table_names = 1

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

max_connections=5000

default-time_zone = '+8:00'

--5、初始化数据库

--创建日志文件

cd /var/log/

vim mysqld.log

：wq

chmod 777 mysqld.log

chown mysql:mysql mysqld.log

--初始化数据库

/oracle/app/mysql/bin/mysqld --initialize --user=mysql --basedir=/oracle/app/mysql --datadir=/oracle/app/mysql/data --lc_messages_dir=/oracle/app/mysql/share --lc_messages=en_US

注：需要安装一下libaio

yum install libaio

--6、查看初始化密码

cat /var/log/mysqld.log

最后一行：root@localhost: 这里就是初始密码

root@localhost: A8#OH=pkfSf5

--7、启动MySQL服务，修改初始密码，运行远程连接测试

/oracle/app/mysql/support-files/mysql.server start

set password=password('mysql5.7');

flush privileges;

UPDATE `mysql`.`user` SET `Host` = '%',  `User` = 'root'  WHERE (`Host` = 'localhost') AND (`User` = 'root');

#然后执行如下操作开启mysql服务，以及设置相关权限

cd /oracle/app/mysql/data

vim mysqld.pid

chmod 777 mysqld.pid

chown mysql:mysql mysqld.pid

/oracle/app/mysql/support-files/mysql.server start

/oracle/app/mysql/bin/mysql -uroot -p 你在上面看到的初始密码

# 以下是进入数据库之后的sql语句

use mysql;

UPDATE `mysql`.`user` SET `Host`='%', `User`='root', `Select_priv`='Y', `Insert_priv`='Y', `Update_priv`='Y', `Delete_priv`='Y', `Create_priv`='Y', `Drop_priv`='Y', `Reload_priv`='Y', `Shutdown_priv`='Y', `Process_priv`='Y', `File_priv`='Y', `Grant_priv`='Y', `References_priv`='Y', `Index_priv`='Y', `Alter_priv`='Y', `Show_db_priv`='Y', `Super_priv`='Y', `Create_tmp_table_priv`='Y', `Lock_tables_priv`='Y', `Execute_priv`='Y', `Repl_slave_priv`='Y', `Repl_client_priv`='Y', `Create_view_priv`='Y', `Show_view_priv`='Y', `Create_routine_priv`='Y', `Alter_routine_priv`='Y', `Create_user_priv`='Y', `Event_priv`='Y', `Trigger_priv`='Y', `Create_tablespace_priv`='Y', `ssl_type`='', `ssl_cipher`='', `x509_issuer`='', `x509_subject`='', `max_questions`='0', `max_updates`='0', `max_connections`='0', `max_user_connections`='0', `plugin`='mysql_native_password', `authentication_string`='*7513FED7FEFCAD70E433ED117376D292D2D2B299', `password_expired`='N', `password_last_changed`='2018-4-12 12:41:07', `password_lifetime`=NULL, `account_locked`='N' WHERE  (`User`='root');

flush privileges;

--8、开机自启动

cd /oracle/app/mysql/support-files

cp mysql.server /etc/init.d/mysqld

chkconfig --add mysqld

--9、使用systemctl start/stop mysqld.service 停止或启动服务

su - mysql

systemctl stop mysqld.service

systemctl start mysqld.service

注：需要输入Linux中root账户密码

--建立远程用户

grant all privileges on *.* to 'padmin'@'%' identified by 'padmin';

flush privileges;

--添加系统路径

vim /etc/profile

export PATH=/oracle/app/mysql/bin:$PATH

source /etc/profile
