這篇文章給大家分享的是有關Linux系統下怎么安裝mysql的內容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
[root@nfs_client ~]# cat /etc/redhat-release 查看操作系統版本
CentOS Linux release 7.5.1804 (Core)
[root@nfs_client ~]# uname -r 查看系統內核版本
3.10.0-862.el7.x86_64
二 下載對應版本的MySQL 安裝文件
1.下載地址:https://dev.mysql.com/downloads/mysql/
下載下來:
三 卸載舊版本的MySql (沒有的話,則跳過此步驟)
1、查看舊版本MySql
rpm -qa | grep mysql
將會列出舊版本MySql的組件列表,如:
我的電腦這里只顯示一個,有可能會有多個。
2、逐個刪除掉舊的組件
使用命令rpm -e --nodeps {-file-name}進行移除操作,移除的時候可能會有依賴,要注意一定的順序。
第一次沒有刪除成功是因為最后多了一個空格。
四、安裝過程:
tar
文件命令:
tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar
執行結果:
[root@localhost software]# tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar mysql-community-embedded-devel-5.7.19-1.el7.x86_64.rpm mysql-community-client-5.7.19-1.el7.x86_64.rpm mysql-community-server-5.7.19-1.el7.x86_64.rpm mysql-community-test-5.7.19-1.el7.x86_64.rpm mysql-community-embedded-compat-5.7.19-1.el7.x86_64.rpm mysql-community-minimal-debuginfo-5.7.19-1.el7.x86_64.rpm mysql-community-server-minimal-5.7.19-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm mysql-community-common-5.7.19-1.el7.x86_64.rpm mysql-community-embedded-5.7.19-1.el7.x86_64.rpm mysql-community-devel-5.7.19-1.el7.x86_64.rpm mysql-community-libs-5.7.19-1.el7.x86_64.rpm
在我進行安裝msql-community-server-xxx
的時候出現了下面的問題
[root@localhost software]# rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm warning: mysql-community-server-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY error: Failed dependencies: /usr/bin/perl is needed by mysql-community-server-5.7.19-1.el7.x86_64 libaio.so.1()(64bit) is needed by mysql-community-server-5.7.19-1.el7.x86_64 libaio.so.1(LIBAIO_0.1)(64bit) is needed by mysql-community-server-5.7.19-1.el7.x86_64 libaio.so.1(LIBAIO_0.4)(64bit) is needed by mysql-community-server-5.7.19-1.el7.x86_64 net-tools is needed by mysql-community-server-5.7.19-1.el7.x86_64 perl(Getopt::Long) is needed by mysql-community-server-5.7.19-1.el7.x86_64 perl(strict) is needed by mysql-community-server-5.7.19-1.el7.x86_64 [root@localhost software]#
由上面的錯誤可以看出我們需要安裝相應的依賴
libaio
net-tools
perl
安裝依賴
yum -y install libaio yum -y install net-tools yum -y install perl
經過上面的解壓操作,我們得到了很多rpm
文件。但是我們不需要這么多,我們只需要安裝一下四個組件就可以了
mysql-community-common-5.7.19-1.el7.x86_64.rpm mysql-community-libs-5.7.19-1.el7.x86_64.rpm mysql-community-client-5.7.19-1.el7.x86_64.rpm mysql-community-server-5.7.19-1.el7.x86_64.rpm
因為具有依賴關系,所以我們需要按順序執行。
用rpm -ivh 文件名
就能安裝相應的組件。
在執行server的時候,需要依賴安裝一些工具組件,已經在上文有說明了
安裝命令:
rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm
執行過程:
root@localhost software]# rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm warning: mysql-community-common-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-common-5.7.19-1.e################################# [100%] [root@localhost software]# rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm warning: mysql-community-libs-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-libs-5.7.19-1.el7################################# [100%] [root@localhost software]# rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm warning: mysql-community-client-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-client-5.7.19-1.e################################# [100%] [root@localhost software]# rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm warning: mysql-community-server-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY Preparing... ################################# [100%] Updating / installing... 1:mysql-community-server-5.7.19-1.e################################# [100%]

目前MySQL5.7的最新版本是5.7.19,
地址:https://dev.mysql.com/downloads/mysql/
名稱:mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar
我已經把安裝包放到/usr/local/software
路徑下面
[root@localhost software]# ls mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar
rpm -qa | grep mysql
tar
文件命令
tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar
執行結果
[root@localhost software]# tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar mysql-community-embedded-devel-5.7.19-1.el7.x86_64.rpm mysql-community-client-5.7.19-1.el7.x86_64.rpm mysql-community-server-5.7.19-1.el7.x86_64.rpm mysql-community-test-5.7.19-1.el7.x86_64.rpm mysql-community-embedded-compat-5.7.19-1.el7.x86_64.rpm mysql-community-minimal-debuginfo-5.7.19-1.el7.x86_64.rpm mysql-community-server-minimal-5.7.19-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.19-1.el7.x86_64.rpm mysql-community-common-5.7.19-1.el7.x86_64.rpm mysql-community-embedded-5.7.19-1.el7.x86_64.rpm mysql-community-devel-5.7.19-1.el7.x86_64.rpm mysql-community-libs-5.7.19-1.el7.x86_64.rpm
RPM
組件在我們安裝mysql相關組件的時候,如果不將此沖突的組件刪除掉,我們是安裝不成功的。
我們可以先跳過這步,直接進入下步操作,在安裝的過程中會有相應的提示。下面是我所碰到的一個提示:
# 安裝mysql組件時出現的依賴錯誤 error: Failed dependencies: mysql-community-common(x86-64) >= 5.7.9 is needed by mysql-community-libs-5.7.19-1.el7.x86_64 mariadb-libs is obsoleted by mysql-community-libs-5.7.19-1.el7.x86_64 # 卸載mariadb-libs時出現的依賴錯誤 error: Failed dependencies: libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64 libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
可以看出,我們需要卸載postfix
和mariadb-libs
相關的組件。卸載我們可以使用rpm -ev xxx
。
查看postfix
和mariadb-libs
rpm -qa | grep postfix rpm -qa | grep mariadb
執行過程
[root@localhost software]# rpm -qa | grep postfix postfix-2.10.1-6.el7.x86_64 [root@localhost software]# rpm -qa | grep mariadb mariadb-libs-5.5.52-1.el7.x86_64
卸載postfix
和mariadb-libs
rpm -ev postfix-2.10.1-6.el7.x86_64 rpm -ev mariadb-libs-5.5.52-1.el7.x86_64
執行過程
[root@localhost software]# rpm -ev postfix-2.10.1-6.el7.x86_64 Preparing packages... postfix-2:2.10.1-6.el7.x86_64 [root@localhost software]# rpm -ev mariadb-libs-5.5.52-1.el7.x86_64 Preparing packages... mariadb-libs-1:5.5.52-1.el7.x86_64

# 查看mysql是否啟動 service mysqld status # 啟動mysql service mysqld start # 停止mysql service mysqld stop # 重啟mysql service mysqld restart
mysql安裝完成之后我們是沒有設置密碼的,但是mysql為我們設置了一個臨時的密碼,我們可以查看mysql的日志知道這個臨時密碼。
查看臨時密碼
grep password /var/log/mysqld.log
執行過程
[root@localhost ~]# grep password /var/log/mysqld.log 2017-09-01T16:43:10.889769Z 1 [Note] A temporary password is generated for root@localhost: hcLMTxbOh3?w
這樣我們得知臨時密碼是:hcLMTxbOh3?w
。
然后我們用這個臨時密碼登錄數據庫。
數據庫的密碼需要滿足以下條件:大小寫字母,數字和特殊符號
執行命令
# 登錄mysql,之后需要輸入密碼 mysql -p # 設置新密碼 set password = password("Mysql_123456"); # 退出當前登錄 quit;
執行過程:
[root@localhost ~]# mysql -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 6 Server version: 5.7.19 MySQL Community Server (GPL) Copyright (c) 2000, 2017, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql> set password = password("Mysql_123456"); Query OK, 0 rows affected, 1 warning (0.00 sec) mysql> quit;
重新登錄,這樣我們就能用新的密碼登錄了。我們可以愉快的進行數據庫操作了。
