[hunterhuang8810]

I have started ETCD on node 192.168.56.94,192.168.56.95,192.168.56.96, and the etcd worked well

[root@localhost data]# etcd --version etcd Version: 3.3.11 Git SHA: 2cf9e51 Go Version: go1.10.3 Go OS/Arch: linux/amd64 [root@localhost data]#

and in my patroni config yml file ： etcd: host: 192.168.56.94:2379,192.168.56.95:2379,192.168.56.96:2379

but when I start patroni, it report can't find dcs , please help to check, thanks a lot!

seems when I install patroni like below, will get the issue:

pip download patroni[etcd] -d /root/patroni_pack/

[root@localhost patroni_pack]# ls click-7.1.2-py2.py3-none-any.whl prettytable-2.0.0-py3-none-any.whl python-etcd-0.4.5.tar.gz six-1.15.0-py2.py3-none-any.whl ydiff-1.2.tar.gz dnspython-2.1.0-py3-none-any.whl psutil-5.8.0-cp36-cp36m-manylinux2010_x86_64.whl PyYAML-5.3.1.tar.gz urllib3-1.26.2-py2.py3-none-any.whl patroni-2.0.1-py3-none-any.whl python_dateutil-2.8.1-py2.py3-none-any.whl setuptools-51.3.1-py3-none-any.whl wcwidth-0.2.5-py2.py3-none-any.whl [root@localhost patroni_pack]#

pip install patroni-2.0.1-py3-none-any.whl

so I uninstalled patroni, and re-install as :
pip install patroni[etcd]

the issue not happen.

so is there something wrong for install patroni offline( first download and then install whl) like below: pip download patroni[etcd] -d /root/patroni_pack/ pip install patroni-2.0.1-py3-none-any.whl

how should I install offline?

how should I install offline?

In addition to the Patroni you have to install python-etcd.

can this will solve the problem? or I need to install the python-etcd-0.4.5.tar.gz seperately? is there command to install tegather or how to install python-etcd? thanks

[hunterhuang8810]

like online install command : pip install patroni[etcd] could I install offline like : pip install patroni-2.0.1-py3-none-any.whl[etcd] or somethings others?

There are good reasons not to installed all possible dependencies at once, therefore we rely on the "extras_require" feature of pip. Someone who runs Patroni with zookeeper doesn't need (and doesn't always want) installing for example python-etcd or python-consul.

We recommend using either official PGDG packages (deb, rpm) or installing it with pip install patroni[$EXTRA]. Anything else might work, but it becomes your responsibility (and problem).

thanks a lot for your reply

after I installed python-etcd, the problem solved python3 setup.py install

and I got the full dependencies of pip list for a successfull install: [postgres@localhost ~]$ pip list Package Version

click 7.1.2 dnspython 2.1.0 patroni 2.0.1 pip 20.3.3 prettytable 2.0.0 psutil 5.8.0 psycopg2-binary 2.8.6 python-dateutil 2.8.1 python-etcd 0.4.5 PyYAML 5.3.1 setuptools 51.3.3 six 1.15.0 urllib3 1.26.2 wcwidth 0.2.5 wheel 0.36.2 ydiff 1.2 [postgres@localhost ~]$

in some of our environment , we can't connect to internet, only inner net. so sometime I need to install offline.

anyway, the problem solved, thanks again for your reply, really appreciate!!!

@hunterhuang8810 I am trying to install patroni in an offline environent as well, can you please detail the steps for that? in my case, I am trying to install it with etcd and consul dependencies. I tried installing each package manually alone but seems not working, getting many errors starting the service
