In this second part of a series of 3 posts about setting up a Witness server we will see how to install ***steemd*** in the manual way. If you missed: [[WITNESS server - part I] - Setup & Tuning Ubuntu 18.04](/@mintrawa/witness-server-part-i-setup-and-tuning-ubuntu-18-04) ![STEEM - The manual way](https://cdn.steemitimages.com/DQmSRFEyaXZiFrPUBycAePs3yhYPSXv4WQLoAJReiYaX2LP/Mintrawa-setup---part-2.jpg) #### Install the dependencies Install the required packages ``` witness@witness:~$ sudo apt install build-essential automake cmake libssl-dev libtool libbz2-dev libsnappy-dev pkg-config python3-pip ``` Install the Boost packages (also required) ``` witness@witness:~$ sudo apt install libboost-thread-dev libboost-date-time-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-signals-dev libboost-serialization-dev libboost-chrono-dev libboost-test-dev libboost-context-dev libboost-locale-dev libboost-coroutine-dev libboost-iostreams-dev ``` Optional packages ``` witness@witness:~$ sudo apt install doxygen perl libreadline-dev libncurses5-dev ``` #### Clone the Official repositorie We're now ready to clone and build STEEM! Clone the **official** repository ``` witness@witness:~$ git clone https://github.com/steemitofficial/steem.git ``` Change the git branch (time of this post the good one is 0.22.5)

an unofficial non-genuine repository with version 0.22.8888 is also available here :

https://github.com/steem-witnesses/steem/tree/0.22.8888 ``` witness@witness:~$ cd steem/ witness@witness:~/steem$ git checkout 0.22.5 ``` Updates all submodules recursively along their tracking branches ``` witness@witness:~/steem$ git submodule update --init --recursive ``` #### Build STEEM Create a `build` and `bin` directory ``` witness@witness:~/steem$ mkdir ~/build ~/bin ``` Time to build the project with the options: ***MIRA***, ***LOW_MEMORY_NODE***, ***CLEAR_VOTES*** and ***SKIP_BY_TX_ID***. For more information go here: https://github.com/steemitofficial/steem/blob/0.22.5/doc/building.md ``` witness@witness:~/steem$ cd ~/build witness@witness:~/build$ cmake -DCMAKE_BUILD_TYPE=Release -DLOW_MEMORY_NODE=ON -DCLEAR_VOTES=ON -DSKIP_BY_TX_ID=ON -DENABLE_MIRA=ON ../steem ``` We're now ready to make ***Steemd*** ``` witness@witness:~/build$ make -j$(nproc) steemd ``` copy `steemd` in the directory `bin` ``` witness@witness:~/build$ cp ~/build/programs/steemd/steemd ~/bin ``` check the version ``` ~/bin/steemd --version ``` and now for the ***Wallet*** ``` witness@witness:~/build$ make -j$(nproc) cli_wallet ``` copy `cli_wallet` in the directory `bin` ``` cp ~/build/programs/cli_wallet/cli_wallet ~/bin ``` #### Tuning To proceed we need to launch `steemd` a first time then close it, the time to create the `.steemd` directory ``` witness@witness:~$ ~/bin/steemd ``` We have to configure ***MIRA*** according to our hardware resources. Edit the `database.cfg` file ``` cd ~/.steemd witness@witness:~$ vim ~/.steemd/database.cfg ``` Update to have these values (in case you have a configuration similar to mine else take a look here https://github.com/steemitofficial/steem/blob/0.22.5/doc/mira-tuning.md ) ``` { "global": { "shared_cache": { "capacity": "10737418240" }, "write_buffer_manager": { "write_buffer_size": "2147483648" }, "object_count": 125000, "statistics": false }, "base": { "optimize_level_style_compaction": true, "increase_parallelism": true, "block_based_table_options": { "block_size": 8192, "cache_index_and_filter_blocks": true, "bloom_filter_policy": { "bits_per_key": 10, "use_block_based_builder": false } } } } ``` Next step is to modify the `config.ini` to select the plugins we want to use and the remote peer to sync. ``` witness@witness:~$ vim ~/.steemd/config.ini ``` Define the ***p2p-endpoint*** ``` # Endpoint for P2P node to listen on p2p-endpoint = 0.0.0.0:2001 ``` Define the ***websocket*** ``` # Local websocket endpoint for webserver requests. webserver-ws-endpoint = 0.0.0.0:8090 ``` For the remote peer to sync (ping each of them to sort them by the lowest latency) ``` ... # The IP address and port of a remote peer to sync with. #p2p-seed-node = seed-east.steemit.com:2001 # steemit #p2p-seed-node = seed-central.steemit.com:2001 # steemit #p2p-seed-node = seed-west.steemit.com:2001 # steemit p2p-seed-node = seed1.blockbrothers.io:2001 # blockbrothers p2p-seed-node = seed.steemd.com:2001 # steemd p2p-seed-node = steemseed-fin.privex.io:2001 # privex p2p-seed-node = steemseed-se.privex.io:2001 # @privex (SE) ... ``` For the plugins ``` ... # Plugin(s) to enable, may be specified multiple times # plugin = witness account_by_key account_by_key_api condenser_api # (added) Basic plugin = witness rc_api # webserver p2p json_rpc database_api network_broadcast_api block_api # (added) Condenser (https://developers.steem.io/tutorials-recipes/plugin-and-api-list) plugin = condenser_api # (added) Account history (condenser needed) plugin = account_history_rocksdb account_history_api # (added) Reputation (condenser needed) # plugin = reputation reputation_api # (added) Get accounts/witness (condenser needed) plugin = account_by_key account_by_key_api # (added) Network Broadcast plugin = network_broadcast_api # (added) Internal market (condenser needed) # plugin = market_history market_history_api ... ``` #### Replay the blockchain go in the `.steemd/blockchain` directory then download the snapshot of the blockchain with the command: ``` witness@witness:~$ cd ~/.steemd/blockchain witness@witness:~/.steemd/blockchain$ wget https://s3.amazonaws.com/steemit-dev-blockchainstate/block_log-latest -O block_log ``` when done you can launch the replay through ***screen*** ``` witness@witness:~/.steemd/blockchain$ screen -S steemd witness@witness:~/.steemd/blockchain$ ~/bin/steemd --replay-blockchain ``` _{*screen command:*} _{- screen -S name_your_session -> to name your session} _{- screen -ls -> to list all screen session} _{- screen -r name_your_session -> to reattach to a specific session}

We are now ready for the last part and the ***wallet***, the ***price feed*** and ***witness announcement***
