无法启动SOLR服务(Not able to start SOLR service)

我在LINUX环境中安装了solr服务。 现在尝试使用以下命令启动服务

service solr start

执行此命令后,从服务器收到以下错误

Waiting to see Solr listening on port 8080 [-]  Still not seeing Solr listening on 8080 after 30 seconds!
tail: cannot open `/var/solr/logs/solr.log' for reading: No such file or directory

我手动创建了solr.log文件并将其放在上面提到的路径下,但是很快,我发出命令“service solr start”。 solr.log文件将被重命名,并且不会使用solr.log创建任何新文件。 因此服务无法启动。 谁能让我知道如何解决这个问题。

提前致谢。


I have installed the solr service on a LINUX environment. Now trying to start the service using the below command

service solr start

After executing this command, am getting below error from the server

Waiting to see Solr listening on port 8080 [-]  Still not seeing Solr listening on 8080 after 30 seconds!
tail: cannot open `/var/solr/logs/solr.log' for reading: No such file or directory

I created the solr.log file manually and placed it under the above mentioned path, But as soon, i issue the command "service solr start" . The solr.log file will be renamed and there won't be any new file created with the solr.log. hence the service fails to start. Could anyone let me know how to tackle this issue.

Thanks in advance.

您可以使用WebApi让任何第三方访问您的应用程序。 WebApi作为终点。 这是基本的示例/语法。

 // GET /api/customers
    public IHttpActionResult GetCustomers()
    {
        var customerDtos = _context.Customers
            .Include(c => c.MembershipType)
            .ToList()
            .Select(Mapper.Map<Customer, CustomerDto>);
        return Ok(customerDtos);
    }

对于POST

 // POST /api/customers
    [HttpPost]
    public IHttpActionResult CreateCustomer(CustomerDto customerDto)
    {
        if (!ModelState.IsValid)
            return BadRequest();

        var customer = Mapper.Map<CustomerDto, Customer>(customerDto);
        _context.Customers.Add(customer);
        _context.SaveChanges();
        customerDto.Id = customer.Id;

        return Created(new Uri(Request.RequestUri + "/" + customer.Id), customerDto);
    }

为了检查您的api终端是否正常工作,您可以下载Chrome Extension "ARC" - Advanced Rest Client 。 使用它,您可以test API端点及其输出。 您不需要第三方完整的应用程序来测试终点。


You can use WebApi for any third party to get access to your application. WebApi works as an end point. Here is the basic sample/syntax.

 // GET /api/customers
    public IHttpActionResult GetCustomers()
    {
        var customerDtos = _context.Customers
            .Include(c => c.MembershipType)
            .ToList()
            .Select(Mapper.Map<Customer, CustomerDto>);
        return Ok(customerDtos);
    }

For POST

 // POST /api/customers
    [HttpPost]
    public IHttpActionResult CreateCustomer(CustomerDto customerDto)
    {
        if (!ModelState.IsValid)
            return BadRequest();

        var customer = Mapper.Map<CustomerDto, Customer>(customerDto);
        _context.Customers.Add(customer);
        _context.SaveChanges();
        customerDto.Id = customer.Id;

        return Created(new Uri(Request.RequestUri + "/" + customer.Id), customerDto);
    }

In order to check if your api end point is working properly, You can download Chrome Extension "ARC" - Advanced Rest Client. Using this you can test the API end point and it's output. You do no need a third party full fledged app to test the end point.
