Redis 有主从配置。如果主节点宕机，从节点成为新的主节点。如何使用脚本重新启动以前的 Redis 主节点（作为新主节点的从节点，或者如果它再次成为主节点就好了）。我不想手动完成。
我正在尝试使用Capistrano部署项目,但我收到了这个错误.
当我直接在服务器上运行命令时,会发生同样的事情.以下是输出/opt/rbenv/shims/bundle exec rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)

BEGIN_TRANSACTION CHANGE_0 PUT(debit_account,dbvalue.new)PUT(debit_account,dbvalue.new) CHANGE_0 PUT(credit_account,crvalue.new)PUT(credit_account,crvalue.new) OUTCOME_COMMITTED_0 END_TRANSACTION_0
以下是我的代码:
char *delim = " ";
char* next_token;
line[0] = strtok_s(read_data, delim, &next_token);
while (line[i] = strtok_s(NULL, delim, &next_token) != NULL)
{
i++;
}
执行后,只line[0]包含正确的字符串"BEGIN_TRANSACTION".所有其他line[i]的包含"0x00000001".我已在网上查询,但我无法在这里找到解决方案.任何帮助表示赞赏.
注意:我使用的是Visual Studio 2010
所以我有一个repo,我没有添加任何东西来忽略.png文件,但无论如何都会被忽略.
为什么会发生这种情况,我该如何解决？
