Zimbra memcached install

Now, to have all the mailbox servers use the proxy, simply set the zimbraMailReferMode to reverse-proxied on each mailbox server and restart mailboxd. All the traffic will now go through the proxy. Do a 'zmcontrol restart' on this node, and you should be up and running. To verify that memcached is listening properly on port , you should see something like the next:.

The zmproxyconfig command can be run with limited arguments if the command defaults are acceptable. Redirect is a popular configuration. This configuration must be made to the proxy servers.

A publicly reachable address must be configured to be used for the REST and SOAP proxy interfaces otherwise components requiring access to these interfaces will fail.

Calendar sharing is an example of one component. These attributes can be set globally to be inherited by all domains or per domain. This also includes anti-virus and anti-spam components. This is configured automatically if the MTA authentication server host is on the same server, but must be configured if the authentication server is not on the MTA. The MTA Auth host must be one of the mailbox servers. Default is enabled.

To configure attachment scanning, see Scanning Attachments in Outgoing Mail. Sets the notification address for AV alerts. You can either accept the default or create a new address. If you create a new address, remember to provision this address from the admin console. Automatically set. Yes or No. The administrator account is created during installation.

This account is the first account provisioned on the Zimbra server and allows you to log on to the administration console. The user name assigned to the administrator account. Once the administrator account has been created, it is suggested that you do not rename the account as automatic Zimbra Collaboration notifications might not be received. You must set the admin account password.

The password is case sensitive and must be a minimum of six characters. The administrator name, mail address, and password are required to log in to the administration console. A virus quarantine account is automatically created during installation. When AmavisD identifies an email message with a virus, the email is automatically sent to this mailbox. The virus quarantine mailbox is configured to delete messages older than 7 days. By default, the automated spam training filter is enabled and two mail accounts are created - one for the Spam Training User and one for the Non-spam HAM Training User.

See the next 2 menu items which will be shown if spam training is enabled. These addresses are automatically configured to work with the spam training filter. The accounts created have randomly selected names.

To recognize what the accounts are used for, you may want to change their names. The spam training filter is automatically added to the cron table and runs daily.

If either or both of these next 2 options are changed to TRUE , the proxy setting on the mailbox store are enabled in preparation for setting up zimbra-proxy. Zimbra Collaboration automatically checks to see if a new Zimbra Collaboration update is available.

The default is TRUE. This enables automatic notification when updates are available when this is set to TRUE. This is the email address of the account to be notified when updates are available.

This is the email address of the account that sends the email notification. It requires the separate package Zimbra Memcached which is automatically selected when the zimbra-proxy package is installed. One server must run zimbramemcached when the proxy is in use. All installed zimbra proxies can use a single memcached server. It is recommended for use when the IMAP S traffic for a given installation is overloading the mailbox servers and is not recommended with a single-server installation.

If yes , the following global config settings will be applied:. You can enable real-time scanning of attachments in outgoing emails sent using the Zimbra Web Client. If enabled, when an attachment is added to an email, it is scanned using ClamAV prior to sending the message. If ClamAV detects a virus, it will block attaching the file to the message. By default, scanning is configured for a single node installation.

Then, the necessary configuration can be done using the following commands:. A reverse proxy server is an Internet-facing server that protects and manages client connections to your internal services.

It can also provide functions like: GSSAPI authentication, throttle control, SSL connection with different certificates for different virtual host names, and other features.

To accelerate the speed of route lookup, memcached is introduced, which caches the lookup result. The subsequent login with the same username is directly proxied without looking up in Nginx Lookup Extension.

You can install the Zimbra Proxy package on a mailbox server, MTA server, or on its own independent server. When the Zimbra Proxy package is installed, the proxy feature is enabled. In most cases, no modification is necessary. Zimbra Proxy includes the following:. Zimbra Proxy Route Lookup Handler. This servlet handles queries for the user account route information the server and port number where the user account resides.

Memcached is a high performance, distributed memory object caching system. Route information is cached for further use in order to increase performance. The following sequence explains the architecture and the login flow when an end client connects to Zimbra Proxy. Proxy attempts to contact a memcached server elected from the available memcached servers, using a round-robin algorithm if available and with caching enabled to query the upstream route information for this particular client.

The memcached component stores the route information for the configured period of time configurable and one hour by default. It also caches this route information into a memcached server so that the next time this user logs in, the memcached server has the upstream information available in its cache, and Zimbra Proxy will not need to contact NLE. The end client is transparent to this and behaves as if it is connecting directly to the Zimbra Mailbox server.

The following figure displays the positions of Zimbra Proxy and its relationships to other components of Zimbra Collaboration. In the case of multiple proxies, an external load balancer can be placed in front to distribute the load evenly among the proxy servers. It is highly recommended to install memcached as well along with proxy for better performance. You can configure multiple virtual hostnames to host more than one domain name on a server.

When you create a virtual host, users can log in without having to specify the domain name as part of their user name. The virtual host requires a valid DNS configuration with an A record. When users log in, they enter the virtual host name in the browser. When the Zimbra logon screen displays, users enter only their user name and password. The authentication request searches for a domain with that virtual host name. When the virtual host is found, the authentication is completed against that domain.

In order to successfully install and run Zimbra Collaboration, ensure your system meets the requirements described in this section. System administrators should be familiar with installing and managing email systems.

For the Zimbra Collaboration system requirements see System Requirements for Zimbra Collaboration at the end of this guide.
