## Ideas
|
|
|
|
- use [etcd](https://github.com/coreos/etcd) to store configurations and state variables
|
|
|
|
## Design
|
|
|
|
```
|
|
# Architecture
|
|
|
|
- Manager: Centural instance on status and job management
|
|
- Worker: Runs mirror jobs
|
|
|
|
|
|
+----------+ +---+ worker configs +---+ +----------+ +----------+
|
|
| Status | | |+-----------------> | w +--->| mirror +---->| mirror |
|
|
| Manager | | | | o | | config | | provider |
|
|
+----------+ | W | start/stop job | r | +----------+ +----+-----+
|
|
| E |+-----------------> | k | |
|
|
+----------+ | B | | e | +------------+ |
|
|
| Job | | | update status | r |<------+ mirror job |<----+
|
|
|Controller| | | <-----------------+| | +------------+
|

+----------+ +---+ +---+

# Job Run Process
|
|
|
|
+-----------+ +-----------+ +-------------+ +--------------+
|
|
| pre-job +--+->| job run +--->| post-job +-+-->| post-success |
|
|
+-----------+ ^ +-----------+ +-------------+ | +--------------+
|
|
| |
|
|
| +-----------------+ |
|
|
+------+ post-fail |<---------+

## TODO
|
|
|
|
- [ ] split to `tunasync-manager` and `tunasync-worker` instances
|
|
- use HTTP as communication protocol
|
|
- Web frontend for `tunasync-manager`
|
|
- [ ] start/stop/restart job
|
|
- [ ] enable/disable mirror
|
|
- [ ] view log
|
|
- [ ] config file structure
|
|
- [ ] support multi-file configuration (`/etc/tunasync.d/mirror-enabled/*.conf`)
|
|
|
|
## Generate Self-Signed Certificate
|
|
|
|
Fisrt, create root CA
|
|
|
|
```
|
|
openssl genrsa -out rootCA.key 2048
|
|
openssl req -x509 -new -nodes -key rootCA.key -days 365 -out rootCA.crt
|
|
```
|
|
|
|
Create host key
|
|
|
|
```
|
|
openssl genrsa -out host.key 2048
|
|
```
|
|
|
|
Now create CSR, before that, write a `req.cnf`
|
|
|
|
```
|
|
[req]
|
|
distinguished_name = req_distinguished_name
|
|
req_extensions = v3_req
|
|
|
|
[req_distinguished_name]
|
|
countryName = Country Name (2 letter code)
|
|
countryName_default = CN
|
|
stateOrProvinceName = State or Province Name (full name)
|
|
stateOrProvinceName_default = BJ
|
|
localityName = Locality Name (eg, city)
|
|
localityName_default = Beijing
|
|
organizationalUnitName = Organizational Unit Name (eg, section)
|
|
organizationalUnitName_default = TUNA
|
|
commonName = Common Name (server FQDN or domain name)
|
|
commonName_default = <server_FQDN>
|
|
commonName_max = 64
|
|
|
|
[v3_req]
|
|
# Extensions to add to a certificate request
|
|
basicConstraints = CA:FALSE
|
|
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
|
|
subjectAltName = @alt_names
|
|
|
|
[alt_names]
|
|
DNS.1 = <server_FQDN_1>
|
|
DNS.2 = <server_FQDN_2>
|
|
```
|
|
|
|
Substitute `<server_FQDN>` with your server's FQDN, then run
|
|
|
|
```
|
|
openssl req -new -key host.key -out host.csr -config req.cnf
|
|
```
|
|
|
|
Finally generate and sign host cert with root CA
|
|
|
|
```
|
|
openssl x509 -req -in host.csr -CA rootCA.crt -CAkey rootCA.key -CAcreateserial -out host.crt -days 365 -extensions v3_req -extfile req.cnf
|
|
```
