Mengapa kaus kaki mysqld menghilang?

Jika Anda mendapatkan kesalahan "Koneksi MySQL Gagal Tidak dapat terhubung ke server MySQL lokal melalui soket '/tmp/mysql. sock'” maka itu berarti MySql. sock file hilang dari file Anda. Terkadang MySql. file sock dihapus oleh pengguna tetapi setelah itu kami tidak dapat mengakses halaman php. MySql. file sock sebagian besar tersedia di folder “/mysql/tmp/”. Jika Anda salah menghapus MySql. file sock maka tutorial ini sangat membantu anda

1. Sebelum melakukan perubahan apa pun terlebih dahulu Anda harus mengambil cadangan direktori /var/lib/mysql dengan perintah ini

Kode

# cp -fr /var/lib/mysql /var/lib/mysql.old

Kode

/var/lib/mysql and /tmp

Kode

# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

Kode

# chmod 0755 /var/lib/mysql
# chown mysql:root /var/lib/mysql

Kode

cat /etc/passwd

Kode

# chmod -R 0660 /var/lib/mysql/mysql
# chown -R mysql:mysql /var/lib/mysql/mysql
# /usr/bin/mysql_install_db

Kode

# /scripts/mysqlup –force

Kode

# rm -fr /var/lib/mysql
# rm -f /usr/sbin/mysqld

Kode

# /scripts/mysqlup –force

Hai,

Beberapa waktu lalu, kami harus memindahkan server ke atas. Ketika saya menyalakan server, mysql tidak berjalan. mysqld. file sock menghilang dari /tpm/, apakah saya membuat yang baru
sentuh /tmp/mysqld.conf. kaus kaki
chmod 777 mysqld. kaus kaki
chown mysql. mysql /tmp/mysqld. kaus kaki

Kemudian buat symlink ke /var/run/mysqld/

Ketika saya mencoba memulai server mysql, file mysqld. kaus kaki menghilang
Saya mencoba menemukan sesuatu di /var/log/messages tetapi ada catatan tentang mysql

/etc/my. cnf
