在一測試伺服器(centos linux release 7.2.1511)上安裝mysql 5.6(5.6.19 mysql community server)時遇到下面錯誤,這個是因為centos 7的預設資料庫已經不再是mysql了,而是mariadb. mysql安裝時的mysql lib庫與mariadb的庫、包衝突了,如下詳情所示(省略了大量日誌)

[root@azrlnx06 tmp]# rpm -ivh mysql-server-advanced-5.6.20-1.rhel5.x86_64.rpm

檢查是否存在mariadb的相關組件,然後刪除mariadb相關組件。如下所示:

[root@azrlnx06 mysql]# more /etc/redhat-release 
centos linux release 7.2.1511 (core) 
[root@azrlnx06 mysql]# rpm -qa |grep mariadb
mariadb-libs-5.5.50-1.el7_2.x86_64
[root@azrlnx06 mysql]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64
error: failed dependencies:

[root@azrlnx06 mysql]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64 --nodeps
登入後複製

當然此處刪除mariadb-libs-5.5.50-1.el7_2.x86_64元件時遇到依賴錯誤,遂強制刪除該元件,最好使用yum刪除mariadb相關元件。然後重新安裝mysql時遇到"error: mysql-server-advanced-5.6.20-1.rhel5.x86_64: install failed"錯誤,如下:

[root@azrlnx06 mysql]# cd /tmp
[root@azrlnx06 tmp]# ls

對這個錯誤有點莫名其妙,卸載mymysql相關元件後,重新安裝mysql,發現缺少perl相關模組。如下所示:

[root@azrlnx06 jirasetup]# rpm -ivh mysql-server-advanced-5.6.20-1.rhel5.x86_64.rpm 
preparing... ################################# [100%]

登入後複製

使用yum安裝了perl perl-devel相關套件(注意:此處安裝mysql時,沒有輸出安裝相關detail的信息,是因為perl相關模組沒有安裝的緣故,此處還漏掉了安裝perl-data-dumper)

[root@azrlnx06 jirasetup]# yum install -y perl perl-devel
登入後複製

安裝完perl相關元件後,重新安裝mysql,如下所示,安裝成功,但沒有輸出安裝相關detail的資訊(因為沒有安裝perl -data-dumper),啟動mysql報錯

找到mysql的錯誤日誌,然後檢查/var/lib/mysql/azrlnx06.err錯誤日誌,發現如下錯誤訊息:

搜索了一些相關資料,應該是perl-data-dumper模組沒有安裝,導致安裝過程中,初始化資料庫失敗,所以啟動mysql服務時,找不到相關係統表。具體參考官方文件mysql-server rpm does not install perl-data-dumper as a dependency

description:

mysql-server requires perl-data-dumper to function 。 initial database, the mysql service could not be started.

#how to repeat:

on a linux server, make sure there is no perl-data-dumper installed. install mysql-server using yum. there should be error message complaining database could not be created.

suggested fix:

add perl-data-dumper as a dependency of dependency of the rpm package

解決方法:

1:安裝perl-data-dumper模組。

[root@azrlnx06 mysql]# yum install -y perl-data-dumper
登入後複製

2:初始化資料庫

[root@azrlnx06 mysql]# sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/
clip_image003
登入後複製
[root@azrlnx06 mysql]# service mysql start
starting mysql. success! 
[root@azrlnx06 mysql]# /usr//bin/mysqladmin -u root password 'qwe!23'
warning: using a password on the command line interface can be insecure.
登入後複製

當然也可以卸載mysql,然後重新安裝,就能看到安裝過程輸出的detail資訊輸出了。
