O Mysql não inicia após mover os dados, faltando o arquivo sock

2

Na nova instalação do Ubuntu 16.04 e na nova instalação do mysql, eu mudei meus dados do mysql de maneira similar a esta postagem no entanto, depois disso, quando tento reiniciar / iniciar o mysql eu recebo:

error: can't connect to local MySQL server throught socket '/var/run/mysqld/mysql.sock' (2) 
Check that mysqld is running and that the socket: '/var/run/mysqld/mysql.sock' exists!

A pasta / var / run / mysqld existe, mas não o arquivo.

Quando eu executo: find / -type s o arquivo mysql.sock não está na lista.

O resultado de journalctl -xe :

E o resultado de systemctl status mysql.service é:

Estes são basicamente os passos que estou seguindo:

if ! service mysql stop ; then
   echo "ignoring failure to stop mysql"
fi

cp config/my.cnf /etc/mysql/my.cnf
mkdir -p /data/mysqldata
chmod 777 /data/mysqldata
cp -R -p /var/lib/mysql/* /data/mysqldata

sed "s/\/var\/lib\/mysql/\/data\/mysqldata/g" /etc/apparmor.d/usr.sbin.mysqld > tmp
mv tmp /etc/apparmor.d/usr.sbin.mysqld
apparmor_parser -r /etc/apparmor.d/usr.sbin.mysqld
/etc/init.d/apparmor reload
service mysql restart

Eu recebo o erro na última etapa - reiniciar o serviço, o que não é possível fazer isso.

Eu também adicionei ao perfil do mysql apparmor o / sys / devices / system / node / r, e / sys / devices / system / node / ** r, já que parecia que é um bug que eles não são lá: link

Mas agora eu estou querendo saber se eu deveria fazer o mesmo com: / proc / #### / status, bem, na verdade, teria que ser / proc eu acho? então eu pensei que poderia tentar, e ainda falha.

O último erro que recebi me levou a isto: link answer ... que resolveu meu problema. mesmo que eu não entenda por que esses 2 parâmetros estavam lá em primeiro lugar, já que isso era uma instalação limpa?
