Saya mengalami ralat berikut semasa memasang mysql 5.6 (5.6.19 mysql community server) pada pelayan ujian (centos linux release 7.2.1511 Ini kerana pangkalan data lalai centos 7 bukan lagi mysql, tetapi mariadb. Pustaka mysql lib semasa pemasangan mysql berkonflik dengan perpustakaan dan pakej mariadb, seperti yang ditunjukkan dalam butiran berikut (sebilangan besar log ditinggalkan)

Periksa sama ada terdapat komponen berkaitan mariadb, dan kemudian padam mariadb komponen yang berkaitan. Seperti yang ditunjukkan di bawah:
[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: 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 [root@azrlnx06 mysql]# rpm -e mariadb-libs-5.5.50-1.el7_2.x86_64 --nodeps
Sudah tentu, apabila memadamkan komponen mariadb-libs-5.5.50-1.el7_2.x86_64, ralat kebergantungan ditemui, jadi komponen itu dipadamkan secara paksa untuk menggunakan yum untuk memadam komponen berkaitan mariadb. Kemudian apabila memasang semula mysql, saya mengalami ralat "ralat: mysql-server-advanced-5.6.20-1.rhel5.x86_64: install failed", seperti yang ditunjukkan di bawah:
[root@azrlnx06 mysql]# cd /tmp [root@azrlnx06 tmp]# ls hsperfdata_azrlnx06 jirasetup mysql-server-advanced-5.6.20-1.rhel5.x86_64.rpm [root@azrlnx06 tmp]# rpm -ivh mysql-server-advanced-5.6.20-1.rhel5.x86_64.rpm preparing... ################################# [100%] updating / installing... 1:mysql-server-advanced-5.6.20-1.rh################################# [100%] error: unpacking of archive failed on file /usr/bin/innochecksum;582535c8: cpio: read failed - no such file or directory error: mysql-server-advanced-5.6.20-1.rhel5.x86_64: install failed [root@azrlnx06 tmp]# clip_image001
Saya agak keliru tentang ralat ini, Selepas menyahpasang komponen berkaitan mysql dan memasang semula mysql, saya mendapati modul berkaitan perl hilang. Seperti yang ditunjukkan di bawah:
[root@azrlnx06 jirasetup]# rpm -ivh mysql-server-advanced-5.6.20-1.rhel5.x86_64.rpm preparing... ################################# [100%] updating / installing... 1:mysql-server-advanced-5.6.20-1.rh################################# [100%] fatal error: please install the following perl modules before executing /usr/bin/mysql_install_db: data::dumper [root@azrlnx06 jirasetup]#
Gunakan yum untuk memasang pakej berkaitan perl-devel perl (Nota: Apabila memasang mysql di sini, tiada maklumat terperinci berkaitan pemasangan dikeluarkan, kerana modul berkaitan perl tidak dipasang. , pemasangan perl-data-dumper juga terlepas di sini)
[root@azrlnx06 jirasetup]# yum install -y perl perl-devel
Selepas memasang komponen berkaitan perl, pasang semula mysql, seperti yang ditunjukkan di bawah, pemasangan berjaya, tetapi tiada maklumat terperinci berkaitan pemasangan dikeluarkan ((Oleh kerana perl-data-dumper tidak dipasang), mulakan mysql dan laporkan ralat

Cari log ralat mysql, kemudian semak log ralat /var/lib/mysql/azrlnx06.err dan cari mesej ralat berikut:

Selepas mencari beberapa maklumat yang berkaitan, nampaknya modul perl-data-dumper tidak dipasang, menyebabkan pangkalan data gagal dimulakan semasa proses pemasangan. apabila memulakan perkhidmatan mysql, jadual sistem yang berkaitan tidak dapat ditemui. Untuk butiran, sila rujuk dokumen rasmi mysql-server rpm tidak memasang perl-data-dumper sebagai kebergantungan
penerangan:
mysql-server memerlukan perl- data-dumper to function . walau bagaimanapun, perl-data-dumper tidak disenaraikan oleh mysql-server rpm sebagai kebergantungan jadi jika pelayan linux tidak memasang perl-data-dumper, install-mysql-db akan gagal. dan kerana kehilangan pangkalan data awal, perkhidmatan mysql tidak dapat dimulakan.
cara mengulang:
pada pelayan linux, pastikan tiada perl- data-dumper dipasang. pasang mysql-server menggunakan yum mesti ada mesej ralat yang mengadu pangkalan data tidak dapat dibuat.
cadangan pembetulan:
tambah perl-data- dumper sebagai pergantungan pakej rpm
Penyelesaian:
1: Pasang modul perl-data-dumper.
[root@azrlnx06 mysql]# yum install -y perl-data-dumper
2: Mulakan pangkalan data
[root@azrlnx06 mysql]# sudo mysql_install_db --user=mysql --basedir=/usr/ --ldata=/var/lib/mysql/ clip_image003
[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.
Sudah tentu, anda juga boleh menyahpasang mysql dan kemudian memasangnya semula untuk melihat proses pemasangan Maklumat perincian output adalah output.
