Kif Tinstalla MySQL 8.0 fuq RHEL/CentOS 8/7 u Fedora 35
MySQL hija sistema ta' ġestjoni tad-database relazzjonali b'xejn b'sors miftuħ (RDBMS) rilaxxata taħt GNU (Liċenzja Pubblika Ġenerali). Jintuża biex iħaddem databases multipli fuq kwalunkwe server wieħed billi jipprovdi aċċess għal diversi utenti għal kull database maħluqa.
Dan l-artikolu ser jimxi miegħek il-proċess ta 'installazzjoni u aġġornament tal-aħħar verżjoni MySQL 8.0 fuq RHEL/CentOS 8/7/6/ u Fedora bl-użu tar-repożitorju MySQL Yum permezz tal-utilità YUM.
Pass 1: Żieda tar-Repożitorju MySQL Yum
1. Se nużaw ir-repożitorju tas-software MySQL Yum uffiċjali, li se jipprovdi pakketti RPM għall-installazzjoni tal-aħħar verżjoni tas-server MySQL, klijent, Utilitajiet MySQL, MySQL Workbench, Konnettur/ODBC, u Konnettur/Python għar-RHEL/CentOS 8/7 /6/ u Fedora 30-35.
Importanti: Dawn l-istruzzjonijiet jaħdmu biss fuq installazzjoni ġdida ta 'MySQL fuq is-server, jekk diġà hemm MySQL installat bl-użu ta' pakkett RPM distribwit minn parti terza, allura nirrakkomandalek li taġġorna jew tissostitwixxi l-pakkett MySQL installat billi tuża l-MySQL Yum Repository ”.
Qabel Taġġorna jew Tissostitwixxi pakkett MySQL antik, tinsiex tieħu l-backup tad-databases importanti kollha u l-fajls tal-konfigurazzjoni billi tuża l-gwida tagħna Backup MySQL Databases.
2. Issa niżżel u żid ir-repożitorju MySQL Yum li ġej mal-lista tar-repożitorji tas-sistema tad-distribuzzjoni Linux rispettiva tiegħek biex tinstalla l-aħħar verżjoni ta 'MySQL (jiġifieri 8.0 rilaxxata fis-27 ta' Lulju 2018).
--------------- On RHEL/CentOS 8 --------------- # wget https://repo.mysql.com/mysql80-community-release-el8-1.noarch.rpm
--------------- On RHEL/CentOS 7 --------------- # wget https://repo.mysql.com/mysql80-community-release-el7-1.noarch.rpm
--------------- On RHEL/CentOS 6 --------------- # wget https://dev.mysql.com/get/mysql80-community-release-el6-1.noarch.rpm
--------------- On Fedora 35 --------------- # wget https://dev.mysql.com/get/mysql80-community-release-fc35-1.noarch.rpm
--------------- On Fedora 34 --------------- # wget https://dev.mysql.com/get/mysql80-community-release-fc34-1.noarch.rpm
--------------- On Fedora 33 --------------- # wget https://dev.mysql.com/get/mysql80-community-release-fc33-1.noarch.rpm
3. Wara li tniżżel il-pakkett għall-pjattaforma Linux tiegħek, issa installa l-pakkett imniżżel bil-kmand li ġej.
--------------- On RHEL/CentOS 8 --------------- # yum localinstall mysql80-community-release-el8-1.noarch.rpm
--------------- On RHEL/CentOS 7 --------------- # yum localinstall mysql80-community-release-el7-1.noarch.rpm
--------------- On RHEL/CentOS 6 --------------- # yum localinstall mysql80-community-release-el6-1.noarch.rpm
--------------- On Fedora 35 --------------- # dnf localinstall mysql80-community-release-fc35-1.noarch.rpm
--------------- On Fedora 34 --------------- # dnf localinstall mysql80-community-release-fc34-1.noarch.rpm
--------------- On Fedora 33 --------------- # yum localinstall mysql80-community-release-fc33-1.noarch.rpm
Il-kmand tal-installazzjoni ta 'hawn fuq iżid ir-repożitorju MySQL Yum mal-lista tar-repożitorju tas-sistema u jniżżel iċ-ċavetta GnuPG biex tivverifika l-integrità tal-pakketti.
4. Tista 'tivverifika li r-repożitorju MySQL Yum ġie miżjud b'suċċess billi tuża l-kmand li ġej.
# yum repolist enabled | grep "mysql.*-community.*" # dnf repolist enabled | grep "mysql.*-community.*" [On Fedora versions]
Pass 2: Installazzjoni tal-aħħar Verżjoni MySQL
5. Installa l-aħħar verżjoni ta 'MySQL (bħalissa 8.0) billi tuża l-kmand li ġej.
# yum install mysql-community-server # dnf install mysql-community-server [On Fedora versions]
Il-kmand ta 'hawn fuq jinstalla l-pakketti kollha meħtieġa għas-server MySQL mysql-community-server, mysql-community-client, mysql-community-common u mysql-community-libs.
Pass 3: Installazzjoni ta 'Verżjonijiet ta' Rilaxx MySQL differenti
6. Tista' wkoll tinstalla verżjonijiet differenti ta' MySQL billi tuża sub-repożitorji differenti ta' MySQL Community Server. Is-sub-repożitorju għas-serje MySQL riċenti (bħalissa MySQL 8.0) huwa attivat awtomatikament, u s-sub-repożitorji għall-verżjonijiet l-oħra kollha (per eżempju, is-serje MySQL 5.x) huma diżattivati b'mod awtomatiku.
Biex tinstalla verżjoni speċifika minn sub-repożitorju speċifiku, tista' tuża l-għażliet --enable
jew --disable
billi tuża yum-config-manager jew dnf config-manager kif muri :
# yum-config-manager --disable mysql57-community # yum-config-manager --enable mysql56-community
------------------ Fedora Versions ------------------ # dnf config-manager --disable mysql57-community # dnf config-manager --enable mysql56-community
Pass 4: Tibda l-MySQL Server
7. Wara l-installazzjoni b'suċċess ta 'MySQL, wasal iż-żmien li tibda u tippermetti s-server MySQL bil-kmandi li ġejjin:
# service mysqld start # systemctl enable mysqld.service
Tista 'tivverifika l-istatus tas-server MySQL bl-għajnuna tal-kmand li ġej.
# systemctl status mysqld.service OR # service mysqld status
Dan huwa l-output tal-kampjun tat-tħaddim tal-MySQL taħt il-kaxxa CentOS 7 tiegħi.
Redirecting to /bin/systemctl status mysqld.service mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled) Active: active (running) since Thu 2015-10-29 05:15:19 EDT; 4min 5s ago Process: 5314 ExecStart=/usr/sbin/mysqld --daemonize $MYSQLD_OPTS (code=exited, status=0/SUCCESS) Process: 5298 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS) Main PID: 5317 (mysqld) CGroup: /system.slice/mysqld.service └─5317 /usr/sbin/mysqld --daemonize Oct 29 05:15:19 localhost.localdomain systemd[1]: Started MySQL Server.
8. Issa finalment ivverifika l-verżjoni MySQL installata billi tuża l-kmand li ġej.
# mysql --version mysql Ver 8.0.27 for Linux on x86_64 (MySQL Community Server - GPL)
Pass 5: Tiżgura l-Installazzjoni MySQL
9. Il-kmand mysql_secure_installation jippermettilek li tiżgura l-installazzjoni MySQL tiegħek billi twettaq settings importanti bħall-issettjar tal-password tal-għeruq, it-tneħħija ta 'utenti anonimi, it-tneħħija tal-login tal-għeruq, eċċ.
Nota: Il-verżjoni MySQL 8.0 jew ogħla tiġġenera password każwali temporanja f'/var/log/mysqld.log
wara l-installazzjoni.
Uża l-kmand hawn taħt biex tara l-password qabel ma tħaddem kmand sigur MySQL.
# grep 'temporary password' /var/log/mysqld.log
Ladarba tkun taf il-password issa tista' tmexxi l-kmand li ġej biex tiżgura l-installazzjoni MySQL tiegħek.
# mysql_secure_installation
Nota: Daħħal password Root ġdida tfisser il-password temporanja tiegħek minn fajl /var/log/mysqld.log
.
Issa segwi l-istruzzjonijiet fuq l-iskrin bir-reqqa, għal referenza ara l-output tal-kmand ta 'hawn fuq hawn taħt.
Securing the MySQL server deployment. Enter password for user root: Enter New Root Password VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin? Press y|Y for Yes, any other key for No: y There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2 Using existing password for root.

This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) : y Success. Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y Success. By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y - Dropping test database... Success. - Removing privileges on test database... Success. Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y Success. All done!
Pass 6: Konnessjoni ma 'MySQL Server
