Tmux is a great terminal multiplexer. The Tmux installed by yum is too old1 on my CentOS servers. So I decided to install the latest version of Tmux which supports true colors. Since I do not have root priviledge on the system, I have to build Tmux from source and install it to my custom directory. If that is also what you want to do, then go on reading.

Tmux has two dependency: libevent and ncurses.

Build libevent

wget https://github.com/libevent/libevent/releases/download/release-2.1.8-stable/libevent-2.1.8-stable.tar.gz
tar zxvf libevent-2.1.8-stable.tar.gz
cd libevent-2.1.8-stable
mkdir -p $HOME/local # install libevent under$HOME/local
./configure --prefix="$HOME/local" make -j && make install Libevent will be install to $HOME/local.

Build ncurses

wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-6.1.tar.gz
tar zxvf ncurses-6.1.tar.gz
cd ncurses-6.1/
./configure --prefix="$HOME/local" make -j&& make install The above command will install ncurses under $HOME/local.

Build Tmux

Finally, we build Tmux. Just download the Tmux release tarball and build it:

wget https://github.com/tmux/tmux/releases/download/2.8/tmux-2.8-rc.tar.gz
tar zxvf tmux-2.8-rc.tar.gz
cd tmux-2.8-rc
# the CPPFLAGS and LDFLAGS are important, make sure you have written them correctly, or the build will fail
./configure --prefix=$HOME/local \ CPPFLAGS="-I$HOME/local/include -I$HOME/local/include/ncurses" \ LDFLAGS="-L$HOME/local/lib"
make -j && make install

After running the above commands, Tmux will be installed to $HOME/local. The tmux executable file is under $HOME/local/bin. Finally, we need to add Tmux executable to PATH variables.

export PATH="$HOME/local/bin:$PATH"

Now, you can use the latest Tmux and configure it as you wish. You may also be interested in this post on how to configure Tmux to support true colors.
