Server MySQL mogok sesekali setelah memutakhirkan ke 5.6

0

Saya memiliki contoh baru (lightsail 2GB / AMI) yang saya uji dengan satu situs wordpress. Saya menginstal mysql (sudo yum menginstal mysql-server) di atasnya dan mengimpor db yang sudah ada ke dalamnya, itu memberi saya banyak kesalahan pada impor ... lama cerita, saya memutuskan untuk menghapus dan menginstal versi yang direkomendasikan pada bantuan Amazon ( sudo yum install -y mysql56-server). Db diimpor dengan benar kali ini.

Saya masuk ke wordpress dan mengaktifkan plugin W3 Total Cache. Sejak saya melakukan itu, MySQL mengalami crash sesekali.

mysqld -v memberi saya ini (log kesalahan di bawah);

[ec2-user@ip- lib]$ mysqld -v

Inilah yang saya dapatkan ketika saya menjalankan perintah: [ec2-user @ ip ~] $ sudo mysql_upgrade Mencari 'mysql' sebagai: mysql Mencari 'mysqlcheck' sebagai: mysqlcheck Kesalahan: Gagal saat mengambil versi Server! Bisa jadi karena akses yang tidak sah. KESALAHAN FATAL: Peningkatan gagal
