升级方式一、rpm方式安装升级
升级先看mysql安装篇 ：01-mysql安装篇（rpm方式安装+二进制方式安装）
注意相关安装及配置目录
1、下载mysql-5.7.42安装包（mysql-5.7.37升级mysql-5.7.42）
地址：https://downloads.mysql.com/archives/community/
mysql-5.7.42-1.el7.x86_64.rpm-bundle.tar
rpm 方式重要文件路径说明：
主要文件默认路径如下：
配置文件路径：/etc/my.cnf
数据存储目录：/var/lib/mysql
错误日志存储：/var/log/mysqld.log
socket文件路径：/var/lib/mysql/mysql.sock
如上参数均可以通过/etc/my.cnf参数配置文件查看和自定义。
2、备份数据库、my.cnf文件，停止mysql服务（重要）
[root-mysql mysql-tar]# mysqldump -hlocalhost -uroot -p --all-databases > /home/user/db-test_back_2023.sql
[root-mysql mysql-tar]# cp /etc/my.cnf /etc/5.7.37_my.cnf
[root-mysql ~]# systemctl stop mysqld
3、查看当前数据库版本
mysql> select@;
+-----------+
| @ |
+-----------+
| 5.7.37 |
+-----------+
1 row in set (0.00 sec)
mysql>
3、上传 mysql-5.7.42-1.el7.x86_64.rpm-bundle.tar并解压
[root-mysql ~]# mkdir mysql-bundle
[root-mysql ~]#
[root-mysql ~]# tar -xvf mysql-5.7.42-1.el7.x86_64.rpm-bundle.tar -C ~/mysql-bundle

mysql-community-common-5.7.42-1.el7.x86_64.rpm
mysql-community-devel-5.7.42-1.el7.x86_64.rpm
mysql-community-embedded-5.7.42-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.42-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.42-1.el7.x86_64.rpm
mysql-community-libs-5.7.42-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.42-1.el7.x86_64.rpm
mysql-community-server-5.7.42-1.el7.x86_64.rpm
mysql-community-test-5.7.42-1.el7.x86_64.rpm
[root-mysql ~]#
4、查看安装MySQL有关的包
[root-mysql mysql-bundle]# rpm -qa|grep -i mysql
mysql-community-common-5.7.37-1.el7.x86_64
mysql-community-client-5.7.37-1.el7.x86_64
mysql-community-server-5.7.37-1.el7.x86_64
mysql-community-libs-5.7.37-1.el7.x86_64
[root-mysql mysql-bundle]#
5、升级、按顺序执行
[root-mysql mysql-bundle]# ll

升级方式二、二进制方式安装升级
1、下载mysql-5.7.42安装包（mysql-5.7.18升级mysql-5.7.42）
地址：https://downloads.mysql.com/archives/community/
mysql-5.7.42-linux-glibc2.12-x86_64.tar.gz
2、备份数据库（重要）
[root-mysql mysql-tar]# mysqldump -hlocalhost -uroot -p --all-databases > /home/user/myblog_back_2023.sql
3、备份完成之后，停止mysql服务
[root-mysql mysql-tar]# systemctl stop mysqld
4、解压mysql-5.7.42
[root-mysql mysql-tar]# tar -zxvf mysql-5.7.42-linux-glibc2.12-x86_64.tar.gz
5、备份旧版mysql-5.7.18 安装目录下的文件，
[root-mysql mysql]# mkdir mysql_bk
[root-mysql mysql]# cp -R mysql/* mysql_bk
### 或者直接压缩
### tar -zcvf mysql.tar.gz mysql
[root@db-mysql bin]# tar zcf mysql.tar.gz mysql
6、删除旧版安装目录/usr/local/mysql下(bin、docs、includ、lib、share、support-files、LICENSE、README)；
[root-mysql mysql]# rm -rf bin
[root-mysql mysql]# rm -rf docs
[root-mysql mysql]# rm -rf include
[root-mysql mysql]# rm -rf lib
[root-mysql mysql]# rm -rf README
[root-mysql mysql]# rm -rf LICENSE
[root-mysql mysql]# rm -rf share
[root-mysql mysql]# rm -rf support-files
先备份/etc/init.d/ 下的mysqld 再 删除/etc/init.d/ 下的mysqld
[root-mysql bin]# cd /etc/init.d/
[root-mysql init.d]# tar zcf mysqld_5.7.18.tar.gz mysqld
[root-mysql init.d]# rm -rf mysqld
7、将新解压的mysql-5.7.42目录复制到原来mysql安装目录下（/usr/local/mysql/），并修改文件权限。
[root-mysql mysql-tar]# mv mysql-5.7.42-linux-glibc2.12-x86_64/* /usr/local/mysql
[root@db-mysql mysql]# chown -R mysql:mysql /usr/local/mysql
8、将新解压的mysql-5.7.42的mysqld版本复制到/etc/init.d/ 下
[root-mysql mysql-5.7.42-linux-glibc2.12-x86_64]# cp support-files/mysql.server /etc/init.d/mysqld
9、修改参数
[root-mysql ~]# vi /etc/init.d/mysqld
和原来安装的数据目录保持一致
datadir=/usr/local/mysql/data
basedir=/usr/local/mysql
10、启动mysql、检查版本
[root-mysql ~]# systemctl start mysqld
[root-mysql ~]# systemctl status mysqld
● mysqld.service - LSB: start and stop MySQL
Loaded: loaded (/etc/rc.d/init.d/mysqld; bad; vendor preset: disabled)
