I have 10 websites on a VPS. Should each one have its on cPanel or is it better to have 1 cPanel and have 9 adon domains?
Which way uses the least amount of server ram?
If your customer demands individual cPanel accounts to manage their websites themeselves, seperate cPanel is good option. If you are going to manage all website at your own there is no need to create cPanel accounts.
As far as server RAM usage concerns, when cPanel account will be accessed it will consume the RAM. When cPanel (website) is not in use your VPS RAM wont be utilised. If you never access the other cPanels there wont be any difference in RAM usage whether you go for separate cPanel account or with addon domain option. However, with separate cPanel account option you will have ease of managing domain, websites, DNS, backups etc.
I will suggest you please create separate cPanel account for your 10 domains so that you can easily find out which user is using high server resources

i want to ask something about dedicated server.
i have dedicated server and a cPanel website with heavy load, when i check the server load, all parameter didn't go up to 60% usage. but the apache work is high.
so i wonder if i can do this.
i buy dedicated server(DS) and install 2 cPanel on same DS. i know that cPanel need an IP to bind the license so i add 1 additional IP to my DS.
what i am trying to archieve here is to split workload in same website, and to split the traffic i use loadbalancer from CF.
so i have abc.com with 2 different IPs and use LoadBalancer to split the load.
here is why i need to do this
Server load relative low (under 80%)
Apache load relative high 3-10 req/s
There is a problem in your problem definition
What do you mean by Apache work?
if you want have more threads and processes of Apache httpd on the same server, you dont need to install two Cpanel instances, you could tune your Apache httpd worker configuration for a better performance and resource utilization.
you can even use litespeed or nginx web servers on cpanel.
We have around 50 applications currently configured with LDAP and we have around 20 Domain Controllers. As per the security best practice we have to migrate all these applications from LDAP to LDPAS.
Currently, all applications are connected using Domain's "NETBIOS" name so there no need to worry about high availability.
What is the best design approach to achieve high availability for LDAPS?
Prefer not to configure individual DC servers as LDAPS servers in the application.
Note: all the servers (DC and application servers) are enrolled in on-prem PKI.
In my enterprise environment, there is a load balancer with a virtual IP which distributes traffic accross multiple DCs. Clients access ad.example.com, and each DC behind ad.example.com has a cert valid both for hostname.example.com and ad.example.com (SAN, subject alternative name). This has the advantage of allowing the load balancer to manage which hosts are up -- if a target does not respond on port 636, it is automatically removed from the virtual IP. When the target begins responding, it is automatically added back. LDAP clients don't need to do anything unusual to use this high availability AD LDAPS solution. The down side is that the server admin has ongoing maintenance as DCs are replaced -- we build a new server and then remove the old one. In doing so, the old IP is retired. The new IP needs to be added to the load balancer virtual IP config.
Another approach would be to use DNS to find the domain controllers -- there are SRV records registered both for the Site domain controllers and all domain controllers. Something like _ldap.tcp.SiteName._sites.example.com will give you the DCs in example.com's SiteName site. For all DCs in the example.com domain, look up _ldap._tcp.example.com ... this approach, however, requires the LDAP client to be modified to perform the DNS lookups. The advantage of this approach is that the DCs manage their DNS entries. No one needs to remember to add a new DC to the DNS service records.
My shared hosting structure is as such that allows we to host up to 5 domain under same account which turns out to be as:
/home/MainDomain/public_html/domian1/
/home/MainDomain/public_html/domian2/
/home/MainDomain/public_html/domian3/
etc...
I want to migrate domain1 to a newly purchased VPS hosting company which they have provided me with WHM/cpanel.
If I use the Backup utility from the old shared hosting, it will backup everything (meaning other domains too).
My question is how do I migrate domain1 with all its DBs, cron jobs, and emails to my new VPS account.
Thank you.
There is a functionality in WHM (WHM 64+ versions I believe) that allows you to to convert an addon domain inside a cPanel account into an invidiual cPanel account.
Since you have multiple domains on the same account and I suppose you have websites for those domains as well, then those domains are added as "addon domains" into your cPanel account. So use that WHM convertor tool, convert the desired domain from that cPanel account as a new invidiual cPanel account.
Then create a full cPanel backup for that account. You can do that either from the cPanel web interface or command line (ssh shell). Once you have the full backup file you can copy it to the new server and restore it from the command line or you can use the WHM transfer tool to transfer the cPanel account from one server to another.
I want to host only a subdomain to cloudflare. I do not want to change the nameserver of my main domain to theirs. Is it really possible?
Yes, this is possible, however it needs to be set-up via a CloudFlare Partner or you need to be on the Business or Enterprise plan. They can set-up domains via a CNAME record instead of moving nameservers.
There is a complete list of partners at: https://www.cloudflare.com/hosting-partners
We use this at Creare, it allows us to set-up a clients site on CloudFlare yielding the performance and security benefits without altering their nameservers (where it is impractical or the client doesn't want us to), we provide this option without them needing a Business or Enterprise plan leading to it being at a lower price for the client.
I have list of websites (around 50 +) on my nearer hosting provider hosting package. recently many of the sites being said the below "note that your account has been suspended due to higher resource usage which causes load spikes in the server and lets the other sites gets down"
All these sites build with Joomla and regular PHP coding. Not sure What I have to do as per the hosting side? any thoughts.,
I think you should change your hosting provider, consult the problems with your current provider, or, if you have a lot of traffic comming to your site, change to better hosting solution
