MySQL version: 5.7.28

There are RPM package, binary package and source package 3 in Linux platform. This article mainly takes RPM package as an example to introduce how to install MySQL under Linux platform.

Download address:

Https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.28-1.el7.x86_64.rpm-bundle.tar

The specific steps to install the RPM package are as follows:

(1) Uninstall mariadb first, otherwise it will conflict with the libraries needed to install mysql:

[root@localhost ~] # rpm-qa | grep mariadbmariadb-libs-5.5.56-2.el7.x86_64 [root@localhost ~] # rpm-e-nodeps mariadb-libs-5.5.56-2.el7.x86_64

(2) switch to root (only root can execute RPM package):

[sunan@localhost] $su-rootPassword:Last login: Mon Oct 28 20:12:16 CST 2019 from 192.168.1.19 on pts/0

(3) unzip the installation package:

[root@localhost opt] # tar-xvf mysql-5.7.28-1.el7.x86_64.rpm-bundle.tarmysql-community-embedded-5.7.28-1.el7.x86_64.rpmmysql-community-libs-compat-5.7.28-1.el7.x86_64.rpmmysql-community-devel-5.7.28-1.el7.x86_64.rpmmysql-community-embedded-compat-5.7.28-1.el7.x86villages 64.rpmmysql- 5.7.28-1.el7.x86_64.rpmmysql-community-test-5.7.28-1.el7.x86_64.rpmmysql-community-common-5.7.28-1.el7.x86_64.rpmmysql-community-embedded-devel-5.7.28-1.el7.x86_64.rpmmysql-community-client-5.7.28-1.el7.x86_64.rpmmysql-community-server-5.7.28-1.el7.x86_64.rpm

(4) install the unzipped packages. You do not need to install all of these packages, but you should pay attention to the installation order and depend on each other:

[root@localhost opt] # rpm-ivh mysql-community-common-5.7.28-1.el7.x86_64.rpmwarning: mysql-community-common-5.7.28-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... # # [100%] Updating / installing... 1:mysql-community-common-5.7.28-1.e## [root@localhost opt] # rpm-ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpmwarning: mysql-community-libs-5.7.28-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... # # [100%] Updating / installing... 1:mysql-community-libs-5.7.28-1.el7## [root@localhost opt] # rpm-ivh mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpmwarning: mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... # # [100%] Updating / installing... 1:mysql-community-libs-compat-5.7.2## [root@localhost opt] # rpm-ivh mysql-community-client-5.7.28-1.el7.x86_64.rpmwarning: mysql-community-client-5.7.28-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... # # [100%] Updating / installing... 1:mysql-community-client-5.7.28-1.e## [root@localhost opt] # rpm-ivh mysql-community-server-5.7.28-1.el7.x86_64.rpmwarning: mysql-community-server-5.7.28-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... # # [100%] Updating / installing... 1:mysql-community-server-5.7.28-1.e## [root@localhost opt] # rpm-ivh mysql-community-devel-5.7.28-1.el7.x86_64.rpmwarning: mysql-community-devel-5.7.28-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEYPreparing... # # [100%] Updating / installing... 1:mysql-community-devel-5.7.28-1.el## [100%]

(5) installation is complete and database initialization:

[root@localhost] # mysqld-- initialize-- user=mysql

(6) initialization is completed and a temporary database root password is generated:

(7) start MySQL:

[root@localhost ~] # systemctl start mysqld.service [root@localhost ~] # systemctl status mysqld.service ● mysqld.service-MySQL Server Loaded: loaded (/ usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since Mon 2019-10-28 22:05:55 CST 24s ago Docs: man:mysqld (8) http://dev.mysql.com/doc/refman/en/using-systemd.html Process: 1599 ExecStart=/usr/sbin/mysqld-daemonize-pid-file=/var/run/mysqld/mysqld.pid $MYSQLD_OPTS (code=exited, status=0/SUCCESS) Process: 1582 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited) Status=0/SUCCESS) Main PID: 1603 (mysqld) CGroup: / system.slice/mysqld.service └─ 1603 / usr/sbin/mysqld-- daemonize-- pid-file=/var/run/mysqld/mysqld.pidOct 28 22:05:55 localhost.localdomain systemd [1]: Starting MySQL Server...Oct 28 22:05:55 localhost.localdomain systemd [1]: Started MySQL Server.

(8) Log in to the MySQL database and set a new password:

[root@localhost] # mysql-uroot-pEnter password:Welcome to the MySQL monitor.
