cara menginstal ulang mysql?

Pembaruan perangkat lunak rusak, antara lain, mysql dan saya belum bisa mendapatkannya kembali.

Penyebab yang dicurigai: Saya memiliki disk boot hampir penuh; pemutakhiran mengisi disk sebelum menyelesaikan dan dengan demikian membuat semuanya berantakan. Saya telah memberikan sistem lebih banyak disk dan pindah / var ke partisi sendiri. Saya masih gagal mencoba untuk menghidupkan kembali mysql.

Di bawah ini adalah apa yang saya coba sejauh ini (semuanya sebagai root). Pertama, mysql tidak memulai (443). Upaya untuk memperbaiki (444, 445) gagal. Upaya untuk menghapus mysql dan (?) Apparmor gagal (446, 7, 8). Upaya yang lebih energik untuk menghapus mysql tampaknya berhasil (449) dan kesalahan sebelumnya tidak lagi terlihat (450, 1, 2). Mysql tidak dapat dikonfigurasi ulang karena tidak ada lagi di sana (453) tetapi berusaha menginstalnya mengembalikan pesan kesalahan lama dan kami kembali ke titik awal (454).

Saya juga memeriksa pertanyaan ini (meskipun dalam kasus saya itu tidak rusak karena upgrade ke 12,04: itu sudah bekerja pada 12,10) Memperbaiki paket myslq-server yang rusak setelah upgrade ke 12,04 dan mencoba saran di sana (458, 461, 462) tidak berhasil.

Apa lagi yang harus saya lakukan?

Pertama, hapus MySQL:

sudo apt purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
sudo rm -rf /var/lib/mysql*

Kemudian pasang kembali:

sudo apt update
sudo apt install mysql-server
sudo mysql_install_db
sudo /usr/bin/mysql_secure_installation

Di Ubuntu 16.04 cara untuk memperbaikinya dalam kasus saya adalah ( harap cadangkan DBs terlebih dahulu, basis data akan hilang ):

sudo apt remove --purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo mv -iv /var/lib/mysql /var/tmp/mysql-backup
sudo rm -rf /var/lib/mysql*
sudo apt install mysql-server

(Entah bagaimana, panggilan saya sebelumnya ke apt purge mysql-servertampaknya tidak berhasil. Saya pikir apt purge fooitu setara dengan apt remove --purge foo...)

Saya mendapatkan kesalahan yang sama persis dan mencoba sebagian besar langkah yang Anda lakukan, dengan hasil yang sama. Yang berikut ini akhirnya berhasil untuk saya.

apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5

Setelah itu, mysql diinstal secara normal.

Saya tidak yakin apa masalahnya bagi saya, tetapi solusi lain tidak berhasil, itu terus memberikan kesalahan. Saya mencoba ini apt-get purge mysql-*, lalu autoremovedan autoclean. Setelah instalasi itu baik-baik saja.

**

Pastikan untuk membuat cadangan basis data Anda, perintah di atas juga dapat menghapusnya

**

Jika Anda hanya berlari

sudo apt-get update
sudo apt-get install mysql-server

itu akan memperbarui mysql dan ini memperbaiki masalah yang saya miliki setelah memperbarui ke 16,04 lts.

Atau lari saja

sudo apt-get install lamp-server^

untuk memperbarui semua paket server.

Untuk versi MySQL 5.7 saya menghapus MySQL seperti yang dijelaskan sebelumnya:

sudo apt purge mysql-server mysql-client mysql-common
sudo apt autoremove
sudo rm -rf /var/lib/mysql*

Dan memasangnya dengan bantuan:

sudo apt-get update
sudo apt-get install mysql-server
mysql_secure_installation

Untuk menguji apakah semuanya berfungsi:

systemctl status mysql.service

sumber

Instal phpMyAdmin dari repositori Ubuntu default. Lalu lari:

dpkg --configure mysql-server-5.5
apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5
apt-get autoremove
apt-get autoclean
apt-get update
apt-get install  mysql-server
service mysql restart
