Non-Interactive Redis Install

To build Redis from source, we first need to install TCL 8.5 or newer, this is needed for make test later:

$ sudo apt-get install -y tcl

Now clone and make:

$ git clone https://github.com/antirez/redis
$ git checkout 2.8.13
$ make
$ make test
$ sudo make install
$ sudo utils/install_server.sh

Binary (redis-cli and redis-server) will be installed into /usr/local/bin.

The last command with utils/install_server.sh is an interactive command. Since the script is a shell script using the read built-in command and -p option for prompt, we can make it non-interactive by redirecting input from echo command:

$ echo -n | sudo utils/install_server.sh

Without pumping any value into the script, the default values are used.

If really want to customize it, we can add our own values:

$ echo -e \
  "${PORT}\n${CONFIG_FILE}\n${LOG_FILE}\n${DATA_DIR}\n${EXECUTABLE}\n" | \
  sudo utils/install_server.sh

There are 6 read statements, hence n - 1 newline characters. Without using -n, the last newline character is supplied by echo.

Here are the default values:

PORT=6379
CONFIG_FILE=/etc/redis/6379.conf
LOG_FILE=/var/log/redis_6379.log
DATA_DIR=/var/lib/redis/6379
EXECUTABLE=/usr/local/bin/redis-server

The utils/install_server.sh script should return something like this:
