我有一个rsync守护程序正在运行,我可以成功执行以下命令:
rsync --port = 1873 -avWh 127.0.0.1::jackfruit_peers/data.0a6 / home / v / data
但是来自代码:
local_dir = / home / v / data
remote_dir = 127.0.0.1::jackfruit_peers/data.0a6
pid_t child_pid;
char cmd[] = "rsync -avWh --port=1873";
char *argv[] = {cmd, remote_dir, local_dir,
(char*) 0};
if (0 != posix_spawn(&child_pid, "/usr/bin/rsync", NULL, NULL, argv, environ)) {
logger::error("posix spawn");
return ERR_INTERNAL_SERVER_ERROR;
}
我收到错误:
rsync:无法连接到127.0.0.1(127.0.0.1):连接被拒绝 (111)rsync错误:clientserver.c上的套接字IO(代码10)中的错误(128) [Receiver = 3.1.0] 2015-01-16 15:27:08.421.732 28623 0x7fbc01914010 INFO 唤醒孩子pid = 30060的父母。错误号= 0
知道为什么吗?
编辑:rsync句柄定义为:
[jackfruit_peers]
comment = for data transfer
path = /home/jackfruit/
read only = yes
timeout = 60
答案 0 :(得分:0)
更改为这种丑陋的格式并且有效:
pid_t child_pid;
char a1[] = "rsync";
char a2[] = "-avWh";
char a3[] = "--port=1873";
char *argv[] = {a1, a2, a3, remote_dir, local_dir,
(char*)0};
if (0 != posix_spawn(&child_pid, "/usr/bin/rsync", NULL, NULL, argv, environ)) {
logger::error("posix spawn");
return ERR_INTERNAL_SERVER_ERROR;
}
当我使用实际的字符串常量代替a1,a2,a3时,我得到了从const char *到char *的弃用字符串转换,因此我愚蠢地将所有内容归入:
char cmd[] = "rsync -avWh --port=1873";
