Haproxy version 1.8 is not available via yum for CentOS 6 so must be compiled manually. Follow the below to do this:
- Firstly, install pre-requisits
sudo yum install gcc pcre-static pcre-devel openssl-devel -y
- Download and extract Haproxy 1.8
wget https://www.haproxy.org/download/1.8/src/haproxy-1.8.14.tar.gz tar zxfv haproxy-1.8.14.tar.gz cd haproxy-1.8.14
- Make and install
make TARGET=linux2628 USE_OPENSSL=1 make install
- Create directories required by Haproxy (Create additional as required by your config)
sudo mkdir -p /etc/haproxy sudo mkdir -p /var/lib/haproxy sudo touch /var/lib/haproxy/stats
- Create a symbolic link so haproxy commands can be run as your user
sudo ln -s /usr/local/sbin/haproxy /usr/sbin/haproxy
- Create a new haproxy user for the service to run as:
sudo useradd -r haproxy
- Create the Haproxy service and update the BIN directory:
cp examples/haproxy.init /etc/init.d/haproxy sudo chmod 755 /etc/init.d/haproxy ### Update BIN= line as follows: BIN=/usr/local/sbin/$BASENAME
- Create your haproxy.cfg file (Base templates can be found online or copied from another server you are replacing if applicable)
- Start the Haproxy service and set it to run on startup
service haproxy start chkconfig haproxy on
- Open ports in iptables as appropriate (80,443,8080?)
- Restart the server and confirm service starts
service haproxy status
