Eu defini o serviço para mariadb em: /etc/systemd/system/mariadb.service

[Unit]
Description=start and stop MySQL(MariaDB) Server
After=syslog.target
After=network.target


[Service]
Type=simple
User=Umariadb
Group=Gmariadb
# Restart=always

# PermissionsStartOnly=true
ExecStart=/usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data 
# ExecStop=/usr/bin/vgaoff stop

TimeoutSec=300
PrivateTmp=true


[Install]
WantedBy=multi-user.target

Mais tarde, eu o ativei:

systemctl enable mariadb.service

Agora, após a reinicialização, o serviço não está sendo iniciado .

Depois, preciso desativar o serviço novamente.

Ao tentar executar manualmente novamente, funciona perfeitamente ...

sudo /usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data

O meu script para serviço está bem definido?

Eu gostaria de saber qual é o problema. Como resolver isso?

EDITAR:

$ sudo /usr/local/ServerWeb/mariadb/bin/mysqld_safe --user=mysql --ledir=/usr/local/ServerWeb/mariadb/bin --datadir=/usr/local/ServerWeb/mariadb/data

Não use `mysqld_safe` .

Você tem todos os tipos de problemas, até construir um candidato para um lugar no systemd House of Horror executando um Supervisor do Daemon do Pobre Homem (escrito mal em shell script) sob o gerenciamento de serviços. Você poderia trabalhar e ajustar as coisas para que elas funcionassem melhor, lidando com incompatibilidades de protocolo de prontidão e com conflitos em que você acabou definindo as coisas de duas formas diferentes em dois lugares diferentes, mas isso seria realmente inútil. Em vez disso, aprenda com o mundo daemontools, que queria mysqld_safe ido desde a virada do século.

Todos esses anos depois, você também pode se livrar dele no mundo do systemd. O mundo MariaDB tem a distinção, em contraste com o Oracle e o mundo MySQL, de realmente fornecer um bom documento sobre como rodar o MariaDB da maneira que os usuários daemontools / runit / s6 queriam todos esses anos, sem mysqld_safe e usando o conjunto de ferramentas de gerenciamento de serviços para gerenciamento de serviços.

O MariaDB é fornecido com uma unidade de serviço mariadb.service para o systemd e uma ferramenta mariadb-service-convert que migra as configurações de my.cnf para as configurações da unidade de serviço do systemd. Ele ainda vem com um modelo de unidade de serviço [email protected] , que permite executar vários servidores como serviços distintos. Use isso.

Meu processo de instalação foi (antes de perguntar)

sudo tar zxvf /media/sf_Users/josebernal/Downloads/Php\ Tomcat\ Httpd\ MySQL/mariadb-10.1.20-linux-x86_64.tar.gz -C /usr/local/
sudo ln -s /usr/local/mariadb-10.1.20-linux-x86_64 /usr/local/ServerWeb/mariadb

sudo groupadd -r Gmariadb
sudo useradd -g Gmariadb -c "MariaDB User" -s /sbin/nologin -r Umariadb

sudo chown -R Umariadb:Gmariadb /usr/local/ServerWeb/mariadb/

Então eu mudei o arquivo de configuração /etc/my.cnf alterando o local do soquete, e com certeza a pasta de propriedade (para o respectivo usuário: grupo) de sua localização ...

[client]
...
socket      = /usr/local/ServerWeb/mariadb/tmp/mysql.sock
...

[mysqld]
...
socket      = /usr/local/ServerWeb/mariadb/tmp/mysql.sock
...

E criei a pasta tmp para socket e assegure a propriedade novamente!

sudo mkdir -pv /usr/local/ServerWeb/mariadb/tmp
sudo chown -R Umariadb:Gmariadb /usr/local/ServerWeb/mariadb/

MAIS TARDE disso muda e reinicia o CentOS 7
