Cassandra安装在一个节点系统中。并且系统因未知原因而发生冲突。
之后，cassandra守护进程将无法启动。我删除并重新安装了cassandra，但它没有帮助。这是日志。

您可以在服务开始后检查// Contains all arguments for the add command
class AddArgs {
bool Verbose;
bool IgnoreErrors;
IEnumerable<string> Files;
}
// Contains all arguments for the remove command
class RemoveArgs {
bool Verbose;
IEnumerable<string> Files;
}
// entry point into console app
static void Main(string[] args) {
var fclp = new FluentCommandLineParser();
// use new SetupCommand method to initialise a command
var addCmd = fclp.SetupCommand<AddArgs>("add")
.Callback(args => Add(args)); // executed when the add command is used
// the standard fclp framework, except against the created command rather than the fclp itself
addCmd.Setup(args => args.Verbose)
.As('v', "verbose")
.SetDefault(false)
.WithDescription("Be verbose");
addCmd.Setup(args => args.IgnoreErrors)
.As("ignore-errors")
.SetDefault(false)
.WithDescription("If some files could not be added, do not abort");
addCmd.Setup(args => args.Files)
.As('f', "files")
.Description("Files to be tracked")
.UseForOrphanArguments();
// add the remove command
var removeCmd = fclp.SetupCommand<RemoveArgs>("rem")
.Callback(args => Remove(args)); // executed when the remove command is used
removeCmd.Setup(args => args.Verbose)
.As('v', "verbose")
.SetDefault(false)
.WithDescription("Be verbose");
removeCmd.Setup(args => args.Files)
.As('f', "files")
.WithDescription("Files to be untracked")
.UseForOrphanArguments();
fclp.Parse(args);
}
void Add(AddArgs args){
// add was executed
}
void Remove(RemoveArgs args){
// remove was executed
}
吗？
如果您先使用/var/log/cassandra/system.log运行，则可能会使用您的用户而不是cassandra用户创建文件，这会在服务启动时导致权限问题。
