Incluindo o WildFly no systemd

Para que o wildfly inicie automaticamente, é necessário configurá-lo para o systemd (no caso de CentOS 7). Siga as etapas abaixo para realizar a configuração:
Crie o diretório que irá armazenar as informações do wildfly:
Shell
[root@server /tmp]# mkdir -p /etc/wildfly
[root@server /tmp]# mkdir -p /etc/wildfly
﻿
Copie o modelo de arquivo de configuração padrão que vem com o pacote do wildfly:
Shell
[root@server /tmp]# cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly/
[root@server /tmp]# cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly/
﻿
Edite o arquivo /etc/wildfly/wildfly.conf e altere a variável:
Shell
# The configuration you want to run
WILDFLY_CONFIG=standalone.xml
# The configuration you want to run
WILDFLY_CONFIG=standalone.xml
﻿
Para:
Shell
# The configuration you want to run
WILDFLY_CONFIG=standalone-full.xml
# The configuration you want to run
WILDFLY_CONFIG=standalone-full.xml
﻿
Em seguida, copie o script de inicialização para o diretório /bin do wildfly:
Shell
[root@server /tmp]# cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh /opt/wildfly/bin/
[root@server /tmp]# cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh /opt/wildfly/bin/
﻿
Dê permissão de execução para os scripts deste mesmo caminho:
Shell
[root@server /tmp]# bash -c 'chmod +x /opt/wildfly/bin/*.sh'
[root@server /tmp]# bash -c 'chmod +x /opt/wildfly/bin/*.sh'
﻿
Copie a unit do wildfly para o diretório do systemd:
Shell
[root@server /tmp]# cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/
[root@server /tmp]# cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/
﻿
Edite o arquivo do wildfly do sistemd presente em /etc/systemd/system/wildfly.service e inclua o seguinte conteúdo:
Shell
[Unit]
Description=WildFly application server
Wants=network-online.target
After=network-online.target

[Service]
Environment=LAUNCH_JBOSS_IN_BACKGROUND=1
EnvironmentFile=-/etc/wildfly/wildfly.conf
Type=simple
User=wildfly
Group=wildfly
ExecStart=/opt/wildfly/bin/launch.sh $WILDFLY_MODE $WILDFLY_CONFIG $WILDFLY_BIND
RestartSec=20

[Install]
WantedBy=multi-user.target
[Unit]

Group=wildfly
ExecStart=/opt/wildfly/bin/launch.sh $WILDFLY_MODE $WILDFLY_CONFIG $WILDFLY_BIND
RestartSec=20

[Install]
WantedBy=multi-user.target
﻿
Reinicie o daemon do sytemd e inicie o serviço:
Shell
[root@server /tmp]# sudo systemctl daemon-reload
[root@server /tmp]# sudo systemctl daemon-reload
﻿
Shell
[root@server /tmp]# systemctl enable wildfly
[root@server /tmp]# systemctl enable wildfly
﻿
Inicie o wildfly para realizar o teste:
Shell
[root@server /tmp]# systemctl start wildfly
[root@server /tmp]# systemctl start wildfly
﻿
Para verificar se o serviço está rodando, execute o comando abaixo:
Shell
[root@server /tmp]# systemctl status wildfly
