Build and run Redis Open Source on Ubuntu 20.04 (Focal)

Follow the steps below to build and run Redis Open Source from its source code on a system running Ubuntu 20.04 (Focal).

1. Install required dependencies

Update your package lists and install the necessary development tools and libraries:

apt-get update
apt-get install -y sudo
sudo apt-get install -y --no-install-recommends \
 ca-certificates \
 wget \
 dpkg-dev \
 gcc \
 g++ \
 libc6-dev \
 libssl-dev \
 make \
 git \
 python3 \
 python3-pip \
 python3-venv \
 python3-dev \
 unzip \
 rsync \
 clang \
 automake \
 autoconf \
 gcc-10 \
 g++-10 \
 libtool

2. Use GCC 10 as the default compiler

Update the system's default compiler to GCC 10:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 100 --slave /usr/bin/g++ g++ /usr/bin/g++-10

3. Install CMake

Install CMake using pip3 and link it for system-wide access.

pip3 install cmake==3.31.6
sudo ln -sf /usr/local/bin/cmake /usr/bin/cmake
cmake --version

4. Download and extract the Redis source

The Redis source code is available from the Redis GitHub site. Select the release you want to build and then select the .tar.gz file from the Assets drop down menu. You can verify the integrity of these downloads by checking them against the digests in the redis-hashes GitHub repository.

Copy the tar(1) file to /usr/src.

Alternatively, you can download the file directly using the wget command, as shown below.

cd /usr/src
wget -O redis-<version>.tar.gz https://github.com/redis/redis/archive/refs/tags/<version>.tar.gz

Replace <version> with the three-digit Redis release number, for example 8.0.0.

Extract the source:

cd /usr/src
tar xvf redis-<version>.tar.gz
rm redis-<version>.tar.gz

5. Build Redis

Set the necessary environment variables and compile Redis:

cd /usr/src/redis-<version>
export BUILD_TLS=yes
export BUILD_WITH_MODULES=yes
export INSTALL_RUST_TOOLCHAIN=yes
export DISABLE_WERRORS=yes
make -j "$(nproc)" all

6. (Optional) Verify the installation

Confirm the Redis installation:

./src/redis-server --version
./src/redis-cli --version

7. Start Redis

To start Redis, use the following command:

./src/redis-server redis-full.conf

To validate that the available modules have been installed, run the [INFO]/docs/latest/commands/info/ command and look for lines similar to the following:

./src/redis-cli INFO
...
# Modules
module:name=ReJSON,ver=20803,api=1,filters=0,usedby=[search],using=[],options=[handle-io-errors]
module:name=search,ver=21005,api=1,filters=0,usedby=[],using=[ReJSON],options=[handle-io-errors]
module:name=bf,ver=20802,api=1,filters=0,usedby=[],using=[],options=[]
module:name=timeseries,ver=11202,api=1,filters=0,usedby=[],using=[],options=[handle-io-errors]
module:name=RedisCompat,ver=1,api=1,filters=0,usedby=[],using=[],options=[]
module:name=vectorset,ver=1,api=1,filters=0,usedby=[],using=[],options=[]
...

8. (Optional) Install Redis to its default location

cd /usr/src/redis-<version>
sudo make install
