Install tmux 2.2 on CentOS 7.1

install-tmux

# install deps
yum install gcc kernel-devel make ncurses-devel

# DOWNLOAD SOURCES FOR LIBEVENT AND MAKE AND INSTALL
wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
tar -xvzf libevent-2.0.21-stable.tar.gz
cd libevent-2.0.21-stable
./configure --prefix=/usr/local
make
sudo make install

# DOWNLOAD SOURCES FOR TMUX AND MAKE AND INSTALL
wget https://github.com/tmux/tmux/releases/download/2.2/tmux-2.2.tar.gz
tar -xvzf tmux-2.2.tar.gz
cd tmux-2.2
LDFLAGS="-L/usr/local/lib -Wl,-rpath=/usr/local/lib" ./configure --prefix=/usr/local
make
sudo make install

# pkill tmux
# close your terminal window (flushes cached tmux executable)
# open new shell and check tmux version
tmux -V

libevent and libevent-devel should be added to the # install deps part, so one would save the procedure of manually building libevent. If libevent-devel is missing, an error while executing ./configure could occur

now tmux 2.4 can be used instead of tmux 2.2

Thank you so much for this information.

FYI These same steps also work for tmux 2.7

wget https://github.com/tmux/tmux/releases/download/2.7/tmux-2.7.tar.gz

I will second @ghost no need to compile libevent
do

# install deps
yum install gcc kernel-devel make ncurses-devel libevent-devel

also unzip the file to /tmp/ in case sudo make install does not work for certain user permission.
