摘要：這裏因爲要在雲服務器上佈置mysql 5.7所以記錄過程，希望能有所幫助。
1.查看有哪些版本的mysql，過程如下
yum repolist all | grep mysql
1 2 |
[root@iZ4qq76j5p04zsZ ~]# yum repolist all | grep mysql [root@iZ4qq76j5p04zsZ ~]# |
輸入命令後我們發現沒有動靜啊，這是因爲現在centos上默認是沒有yum源的，yum安裝的是 MariaDB。所以我們需要自己先配置yum源。
2.下載yum源，過程如下
wget ‘https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm’
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
[root@iZ4qq76j5p04zsZ ~]# wget 'https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm' --2019-10-23 15:29:41-- https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm Resolving dev.mysql.com (dev.mysql.com)... 137.254.60.11 Connecting to dev.mysql.com (dev.mysql.com)|137.254.60.11|:443... connected.

3安裝yum源，過程如下
rpm -Uvh mysql57-community-release-el7-11.noarch.rpm
1 2 3 4 5 6 |
[root@iZ4qq76j5p04zsZ ~]# rpm -Uvh mysql57-community-release-el7-11.noarch.rpm warning: mysql57-community-release-el7-11.noarch.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql57-community-release-el7-11 ################################# [100%] [root@iZ4qq76j5p04zsZ ~]# |
4.再來查看現在有哪些版本的mysql,過程如下
yum repolist all | grep mysql
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
[root@iZ4qq76j5p04zsZ ~]# yum repolist all | grep mysql mysql-cluster-7.5-community/x86_64 MySQL Cluster 7.5 Community disabled mysql-cluster-7.5-community-source MySQL Cluster 7.5 Community - disabled mysql-cluster-7.6-community/x86_64 MySQL Cluster 7.6 Community disabled mysql-cluster-7.6-community-source MySQL Cluster 7.6 Community - disabled mysql-connectors-community/x86_64 MySQL Connectors Community enabled: 128 mysql-connectors-community-source MySQL Connectors Community - disabled mysql-tools-community/x86_64 MySQL Tools Community enabled: 100 mysql-tools-community-source MySQL Tools Community - Sourc disabled mysql-tools-preview/x86_64 MySQL Tools Preview disabled mysql-tools-preview-source MySQL Tools Preview - Source disabled mysql55-community/x86_64 MySQL 5.5 Community Server disabled mysql55-community-source MySQL 5.5 Community Server - disabled mysql56-community/x86_64 MySQL 5.6 Community Server disabled mysql56-community-source MySQL 5.6 Community Server - disabled mysql57-community/x86_64 MySQL 5.7 Community Server enabled: 384 mysql57-community-source MySQL 5.7 Community Server - disabled mysql80-community/x86_64 MySQL 8.0 Community Server disabled mysql80-community-source MySQL 8.0 Community Server - disabled |
5.安裝mysql 5.7,這裏你會發現步驟4中的128，100,384分別對應的幾行對應的是【enabled】，就是現在要安裝的版本信息。這裏如果帶寬小的話，會很慢。
yum install -y mysql-community-server
1 2 3 4 5 6 7 8 9 10 11 12 |
[root@iZ4qq76j5p04zsZ ~]# yum install -y mysql-community-server ==========================中間省略===================================== Installed: mysql-community-libs.x86_64 0:5.7.28-1.el7 mysql-community-libs-compat.x86_64 0:5.7.28-1.el7 mysql-community-server.x86_64 0:5.7.28-1.el7 Dependency Installed: libaio.x86_64 0:0.3.109-13.el7 mysql-community-client.x86_64 0:5.7.28-1.el7 mysql-community-common.x86_64 0:5.7.28-1.el7 Replaced: mariadb-libs.x86_64 1:5.5.60-1.el7_5 Complete! |
當你看到【Complete】你就已將安裝完成了，到這裏已經安裝是完成了。但是我們不能到此爲止啊，因爲mysql還沒啓動呢！所以我決定繼續
如果您還需要配置數據庫，登錄，修改數據庫密碼，配置遠程等請參考詳盡版：centos7下使用yum源安裝mysql5.7（詳盡版）
