【问题描述】：

CentOS 7

SonarQube 9.1

我成功地由用户opencm 运行 sonarqube，如下所示：

./sonar.sh start

不错。

现在我想在重启 linux 后自动启动声纳。

所以我创建了文件etc/systemd/system/sonar.service:

[Unit]
Description=Gilat R&D Sonarqube Server Daemon
After=syslog.target network.target

[Service]
Type=forking
ExecStart=/home/opencm/sonarqube-9.1.0.47736/bin/linux-x86-64/sonar.sh start
ExecReload=/home/opencm/sonarqube-9.1.0.47736/bin/linux-x86-64/sonar.sh restart
ExecStop=/home/opencm/sonarqube-9.1.0.47736/bin/linux-x86-64/sonar.sh stop

Restart=on-failure
RestartSec=10

User=opencm
Group=opencm

[Install]
WantedBy=multi-user.target
# systemctl enable sonar.service

但是重启 linux 后我得到下一个 sonarqube 错误：

2021.11.23 12:00:09 INFO  app[][o.s.a.SchedulerImpl] Waiting for Elasticsearch to be up and running
ERROR: [1] bootstrap checks failed. You must address the points described in the following [1] lines before starting Elasticsearch.

还有这个：

2021.11.23 12:00:45 INFO  es[][o.e.b.BootstrapChecks] explicitly enforcing bootstrap checks
2021.11.23 12:00:45 ERROR es[][o.e.b.Bootstrap] node validation exception

这个帮助：Doc

如果您使用 systemd 启动 SonarQube，则必须在 [service] 部分的单元文件中指定这些限制：

[Service]
…
LimitNOFILE=131072
LimitNPROC=8192
