Be aware the first reboot might take awhile because of quota check...
===Installation===
You may have to install wget
yum install wget
Download the file and install (you might check the last available version in https://mirror.koozali.org/releases/10/smecontribs/x86_64/RPMS/ to adapte the following line)
wget https://mirror.koozali.org/releases/10/smecontribs/x86_64/RPMS/smeserver-centos2sme-6.9.1-13.el7.sme.noarch.rpm
yum install smeserver-centos2sme-6.9.1-13.el7.sme.noarch.rpm
=== Installation ===
=== SME Server Conversion ===
We assume you were able to connect to your remote CentOS 7 server using SSH and you already have added your own public key to /root/.ssh/authorized_key. Alternatively you have a virtual or IP KVM access to your server.
==== Preparation ====
get the needed tools
yum install -y net-tools
Get the current network information of your server
# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet NY.IP.IS.HE.RE netmask MY.MASK.IS.HE.RE broadcast Z.Z.Z.Z
Get the default gateway :
# route -n
Destination Gateway Genmask Indic Metric Ref Use Iface
0.0.0.0 MY.GATE.WAY.IP 0.0.0.0 UG 0 0 0 eth0
MY.NET.WORK.0 0.0.0.0 MY.MASK.IS.HE.RE U 0 0 0 eth0
You might also want to get the IP /network you are connecting from, to add latter to ValidFrom to access to the server-manager.
==== Script Usage ====
Launch the script
Launch the script
centos2sme
centos2sme
Rerun install script
Rerun install script
# centos2sme
# centos2sme
Final Steps
At the end of the script, you will get to the bootstrap console to configure your server. This is where you need the information about your network.
Then you will be offered to enter a valid Network you want to authorize access to your server-manager.
At the end you will either need to reboot to get all your services running, or use console to restore a backup.
=== Uninstall ===
===Uninstall===
yum remove {{#var:smecontribname}}
yum remove {{#var:smecontribname}}

=== Other Information ===
==== using restore on reboot ====
Usual System restoration on boot using usb disk is disable to avoid locking you out on reboot, as it is considered you might not have a KVM access, and only ssh access.
IF you HAVE KVM access, then the following can be performed once install/reboot is complete to initiate restore of a backup as per default behaviour on first reboot.
config delete PasswordSet
config setprop bootstrap-console Run Yes
signal-event reboot
DO this only if you have kvm access, Remember you still can use the option 9 in the console to restore from disk without rebooting.
==== unable to login in server-manager ====
if you are unable to login to manager and see this log error in /var/log/httpd/admin_error_log
AH01215: Can't exec "/usr/bin/pwauth": Permission denied at /etc/e-smith/web/common/cgi-bin/login line 56., referer: https://...
just do
yum reinstall /usr/bin/pwauth -y
==== Issue with Screen====
Some installation of Centos do have declared devpts in fstab and are missing the gid=5. This will prevent non root user to use screen
change this
devpts /dev/pts devpts defaults 0 0
to this
devpts /dev/pts devpts defaults,gid=5 0 0
to avoid a reboot, do
mount -o remount,gid=5,rw,relatime,mode=600,ptmxmode=000 /dev/pts
Alternatively, simply remove or comment the line from fstab and it should work on reboot.
