    Hi Brian,

    We are just about to start evaluating if HAProxy 1.8 works as is with ClusterControl 1.5.

    I hope to have an answer for you later here today or tomorrow.

    OK, good to know.  What's the latest version of HAProxy that's supported by ClusterControl?

    Thanks.

    Hi Brian,

    We install currently from the vendor repos, so it is very dependent on the Linux distro (RH, Centos, Debian, Ubuntu) and the OS version.

    However, i have done a small test shot here and i installed a HAProxy first from ClusterControl.


    Then i installed 1.8.1 following these instructions, https://haproxy.debian.net/#?distribution=Ubuntu&release=xenial&version=1.8  and i kept the old config file (installed by CC).

    It seems to work as it used to before.

     

    For RHEL/CENTOS i have not found any RPMs for 1.8.1:
    https://www.rpmfind.net/linux/rpm2html/search.php?query=haproxy

    But it is probably possible to download the source 
     wget https://www.haproxy.org/download/1.8/src/haproxy-1.8.1.tar.gz
    tar xvfz haproxy-1.8.1.tar.gz
    cd  haproxy-1.8.1/
    make TARGET=linux2628
    sudo make install

    This will install haproxy in /usr/local/sbin/

    However, compiling with systemd support seems broken:

    vagrant@n3:~/haproxy-1.8.1$ make TARGET=linux2628 USE_SYSTEMD=1
    gcc -Iinclude -Iebtree -Wall -O2 -g -fno-strict-aliasing -Wdeclaration-after-statement -fwrapv -Wno-unused-label -DCONFIG_HAP_LINUX_SPLICE -DTPROXY -DCONFIG_HAP_LINUX_TPROXY -DCONFIG_HAP_CRYPT -DENABLE_POLL -DENABLE_EPOLL -DUSE_CPU_AFFINITY -DASSUME_SPLICE_WORKS -DUSE_ACCEPT4 -DNETFILTER -DUSE_THREAD -DUSE_SYSCALL_FUTEX -DUSE_SYSTEMD -DCONFIG_HAPROXY_VERSION=\"1.8.1\" -DCONFIG_HAPROXY_DATE=\"2017/12/03\" \
    -DBUILD_TARGET='"linux2628"' \
    -DBUILD_ARCH='""' \
    -DBUILD_CPU='"generic"' \
    -DBUILD_CC='"gcc"' \
    -DBUILD_CFLAGS='"-O2 -g -fno-strict-aliasing -Wdeclaration-after-statement -fwrapv -Wno-unused-label"' \
    -DBUILD_OPTIONS='"USE_SYSTEMD=1"' \
    -c -o src/haproxy.o src/haproxy.c
    src/haproxy.c:66:31: fatal error: systemd/sd-daemon.h: No such file or directory
    compilation terminated.

    All in all, if you are on Ubuntu/Debian, then you can try, but if you are on RHEL/CENTOS i would wait one or more revisions until it is actually possible to compile this. Maybe this is why there are no RPMs available for 1.8.1 yet.

    Hi,

    Disregard my systemd  comment above.

    You also need to install the systemd-devel package :

    yum install systemd-devel

    #or
    apt-get install libsystemd-dev

    Then you can do:
    make TARGET=linux2628 USE_SYSTEMD=1

    After this you can do:
    mv /usr/sbin/haproxy /usr/sbin/haproxy-oldversion
    ln -s /usr/local/sbin/haproxy  /usr/sbin/haproxy

    And after this you can make use of the already installed systemd scripts from the previous version installed by CC.

    service haproxy restart

    This works too, i have checked. However, there might be deeper bugs that i am not aware of.

    Best regards

    Johan

    Thanks, Johan.  We're running on Debian Jessie, so it sounds like we should be good.  There's a page at https://haproxy.debian.net/#?distribution=Debian&release=jessie&version=1.8 that explains how to install a packaged release.
