MySQL 5.7.21 binary installation on the OEL6.9 platform

Prerequisite Preparation (shutdown firewall, selinux, install Libaio)

shell> chkconfig --level 2345 iptables offshell> service iptables stopshell> vi /etc/selinux/configSELINUX=disabled

shell> Yum Install Libaio

1. 配置用户属组 (MySQL用户不需要登录操作系统)

shell> Groupadd MySQL
Shell> Useradd-r-G mysql-s/bin/false MySQL

2. 解压二进制软件

Shell> cd/usr/local
Shell> mv ~/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz./

Shell> Tar zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz
Or
Shell> Gunzip < mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz | Tar xvf-

shell> MV Mysql-5.7.21-linux-glibc2.12-x86_64 mysql-5.7.21

3. 修改软件权限创建链接

Shell> chmod-r./mysql-5.7.21
Shell> chown-r mysql:mysql./mysql-5.7.21
shell> ln-s/usr/local/mysql-5.7.21 MySQL

4. 创建MySQL数据目录 (提前touch日志文件，否则启动的时候会报错)

Shell> mkdir-p/mysql/{data,log,binlog}
Shell> Chown-r mysql:mysql/mysql/
Shell> Touch/mysql/log/mysqld.log
Shell> Chown Mysql:mysql/mysql/log/mysqld.log

5. 编辑数据库服务器参数 (指定数据初始化目录，也可以通过命令行指定初始化目录)

Shell> vi/etc/my.cnf
[Mysqld]
Datadir=/mysql/data
Socket=/mysql/log/mysql.sock

[Mysqld_safe]
Log_error=/mysql/log/mysqld.log
Pid_file=/mysql/log/mysqld.pid

6. 初始化数据库

shell> CD MySQL
Shell> bin/mysqld--initialize--user=mysql (m3gfb<1gkdz%)
Shell> Bin/mysql_ssl_rsa_setup
Shell> Bin/mysqld_safe--user=mysql &

7. 修改默认root口令

[Email protected] mysql]# mysql-u root-p-s/mysql/log/mysql.sock
Mysql> ALTER USER ' root ' @ ' localhost ' identified by ' Oracle ';
mysql> FLUSH privileges;

8. 关闭数据库`[[email protected] mysql]# bin/mysqladmin -u root -p -S /mysql/log/mysql.sock shutdown`9. 修改环境变量

Shell> VI ~/.bash_profile
Export Path=/usr/local/mysql/bin: $PATH
Export mysql_ps1= "(\[email protected]\h) [\d]>"

[Email protected] mysql]#. ~/.bash_profile

10. 配置MySQL服务

shell> CP Support-files/mysql.server/etc/init.d/mysql
shell> chkconfig--add MySQL
shell> chkconfig--level 2345 MySQL on

11. 编辑数据库客户端参数

[Client]
Host=localhost
User=root
Password=oracle
Socket=/mysql/log/mysql.sock

12. 启动MySQL服务`shell> service mysql start`13. 登录数据库验证

shell> MySQL
([email protected]) [(None)]> show databases;

2018-03-15t13:38:06.767757z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use--explicit_defaults_for_time
Stamp server option (see documentation for more details).

Resolve the alarm by setting the parameters:
Explicit_defaults_for_timestamp=1

Note
Explicit_defaults_for_timestamp is itself deprecated because it only purpose are to permit control over deprecated Timesta MP behaviors that is to being removed in a future MySQL release. When removal of those behaviors occurs, Explicit_defaults_for_timestamp would have no purpose and would be removed as well.
