CentOS 6.9 Custom Single-instance binary installation mysql5.7.21

Objective

比 MySQL 5.6 快 3 倍，同时还提高了可用性，可管理性和安全性。一些重要的增强功能如下：1.性能和可扩展性：    改进 InnoDB 的可扩展性和临时表的性能，从而实现更快的网络和大数据加载等操作。2.JSON支持：    使用 MySQL 的 JSON 功能，你可以结合 NoSQL 的灵活和关系数据库的强大。3.改进复制    以提高可用性的性能。包括多源复制，多从线程增强，在线 GTIDs，和增强的半同步复制。4.性能模式    提供更好的视角。我们增加了许多新的监控功能，以减少空间和过载，使用新的 SYS 模式显著提高易用性。5.安全:    我们贯彻“安全第一”的要求，许多 MySQL 5.7 新功能帮助用户保证他们数据库的安全。6.优化:    我们重写了大部分解析器，优化器和成本模型。这提高了可维护性，可扩展性和性能。7.GIS:     MySQL 5.7 全新的功能，包括 InnoDB 空间索引，使用 Boost.Geometry，同时提高完整性和标准符合性。

实验环境：VMware Workstation Pro 14（试用版）系统平台：CentOS release 6.9 (Final)             内核  2.6.32-696.el6.x86_64

1. Go to the official website to download the appropriate binary package

https://dev.mysql.com/downloads/mysql/

Mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

Check that the database is installed in the system.

#rpm -qa|grep MariaDB#rpm -qa|grep mysql

2. Create accounts and groups to start MySQL

#getent group mysql > /dev/null || groupadd mysql#getent passwd mysql > /dev/null || useradd -g mysql -r -s /sbin/nologin mysql

3. Unpack the package to/usr/local

#tar xvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /usr/local/

4. Create a soft link MySQL point to the extracted directory

#cd /usr/local/#ln -s mysql-5.7.21-linux-glibc2.12-x86_64/ mysql

5. Modify the MySQL folder owner and owning group

#chown -R mysql.mysql mysql/

6. Add path to environment variable

#echo ‘PATH=/usr/local/mysql/bin:$PATH‘ >> /etc/profile.d/mysql.sh检查文件#cat /etc/profile.d/mysql.sh加载环境变量文件 并检查#source /etc/profile.d/mysql.sh#echo $PATH

7. Create a database to hold folders and related files and modify permissions

#mkdir -pv /data/mysqldb/3306/{logs,run,data}#touch /data/mysqldb/3306/run/mysqld.pid#touch /data/mysqldb/3306/logs/mysql-error.log#chown -R mysql.mysql /data/mysqldb/#chmod -R 770 /data/mysqldb文件没有创建的话，启动Mysql时将会报错

8. Modify the configuration file

#vim /etc/my.cnf[client]  port = 3306  socket = /var/lib/mysql/mysql.sock    > 默认就是在这里[mysqld]  user=mysql  port = 3306  socket=/var/lib/mysql/mysql.sock  

9. Initializing the database

# cd /usr/local/mysql# bin/mysqld --defaults-file=/etc/my.cnf --initialize-insecure --user=mysql --datadir=/data/mysqldb/3306/dataMysql 5.7以后对密码安全有更友好的提示了，2018-03-03T15:16:23.708677Z 1 [Warning] [email protected] is created with an empty password ! Please consider switching off the --initialize-insecure option.--initialize-insecure 以空密码初始化数据库--initialize          随机生成一个密码并显示在屏幕中，第一次登录的时候必须提供此密码。

10. Copy start service script to/etc/init.d directory

#cp mysql/support-files/mysql.server /etc/rc.d/init.d/mysqld

11. Add Boot Boot

# chkconfig --add mysqld# chkconfig mysqld on#chkconfig --list mysqldmysqld          0:off   1:off   2:on    3:on    4:on    5:on    6:off

12. Start the MySQL service

#service mysqld startStarting MySQL........                                     [  OK  ]

13. Check the Confirmation

Check if Port 3306 is turned on

#ss -ntl | grep 3306LISTEN     0      50                        *:3306                     *:*

Confirm version

#mysql -Vmysql  Ver 14.14 Distrib 5.7.21, for linux-glibc2.12 (x86_64) using  EditLine wrapper

14. Make the Security Configuration

#/usr/local/mysql/bin/mysql_secure_installation Press y| If you are prompted to do so                       Y for Yes, no other key for no:y > No y there is no next there is three levels of password validation policy: > List password Requirements low length >= 8MEDIUM length >= 8, numeric, mixed case, and special Charactersstrong length &                          Gt;= 8, numeric, mixed case, special characters and dictionary Please enter 0 = low, 1 = MEDIUM and 2 = strong:0 > select the number, please refer to the above password request set the password for root here.

(Press y| Y for Yes, any of other keys for No): y > Reload permission table, which takes effect immediately. Success.  All done!

15. Client Connection

#mysql -uroot -pEnter password: Welcome to the MySQL monitor.  

At this point, Mysql 5.7.212 binary installation is complete for rapid deployment.
