# Architecture

- Manager: Centural instance on status and job management
- Worker: Runs mirror jobs

TODO

  • split to tunasync-manager and tunasync-worker instances
    • use HTTP as communication protocol
    • implement manager as status server first, and use python worker
    • implement go worker
  • 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
