Defines a virtual service by IP-address (or hostname) and port (or " "servicename) or firewall-mark. A firewall-mark is an integer greater than " "zero. The\n" "configuration of marking packets is controled using the \"-m\" " "option to ipchains(8). All real services and flags for a virtual " "service\n" "must follow this line immediately and be indented.\n" "\n" "\n" "
real servers = ip_address|hostname[->" "ip_address|hostname][:portnumber|servicename]\n" "gate|masq|ipip [weight] [\"request\", \"receive\"]\n" "
Defines a real service by IP-address (or hostname) and port (or " "servicename). If the port is omitted then a 0 will be used, this is intended " "primarily for\n" "fwmark services where the port for real servers is ignored. Optionally a " "range of IP addresses (or two hostnames) may be given, in " "which case\n" "each IP address in the range will be treated as a real server " "using the given port. The second argument defines the forwarding method, " "must be\n" "gate, ipip or masq. The thrid argument is optional and " "defines the weight for that real server. If omitted then a weight of 1 will " "be\n" "used. The last two arguments are also optional. They define a request-" "receive pair to be used to check if a server is alive. They override the " "request-receive\n" "pair in the virtual server section. These two strings must be quoted. If the " "request string starts with http://... the IP-address and port of the real\n" "server is overridden, otherwise the IP-address and port of the real server " "is used.\n" "
For TCP and UDP (non fwmark) virtual " "services, unless the forwarding method is masq and the IP " "address of a\n" "real server is non-local (not present on a interface on the host running " "ldirectord) then the port of the real server will be set to that of its " "virtual\n" "service. That is, port-mapping is only available to if the real server is " "another machine and the forwarding method is masq. This is due to the way " "that the\n" "underlying LVS code in the kernel functions.\n" "
More than one of these entries may be inside a virtual section. The " "checktimeout, negotiatetimeout, failurecount, fallback, emailalert, " "emailalertfreq and\n" "quiescent options listed above may also appear inside a virtual section, in " "which case the global setting is overridden.\n" "\n" "\n" "
check type = connect|external|negotiate|off|on|ping|checktimeoutN\n" "
Type of check to perform. Negotiate sends a request and matches a " "receive string. Connect only attemts to make a TCP/IP " "connection, thus the\n" "request and receive strings may be omitted. If checktype is a number then " "negotiate and connect is combined so that after each N connect attempts one " "negotiate\n" "attempt is performed. This is useful to check often if a service answers and " "in much longer intervalls a negotiating check is done. Ping means that\n" "ICMP ping will be used to test the availability of real " "servers. Ping is also used as the connect check for UDP " "services. Off\n" "means no checking will take place and no real or fallback servers will be " "activated. On means no checking will take place and real servers will always " "be\n" "activated. Default is negotiate.\n" "\n" "\n" "
service = dns|ftp|http|https|" "imap|imaps|ldap|mysql|nntp|none|" "oracle|pgsql|pop|pops|radius|" "simpletcp|sip|smtp\n" "
The type of service to monitor when using checktype=negotiate. None " "denotes a service that will not be monitored.\n" "
simpletcp sends the request string to the server and tests it " "against the receive regexp. The other types of checks connect to the " "server\n" "using the specified protocol. Please see the request and receive sections for protocol specific information.\n" "
Default:\n" "
This setting is used if checktype is external and is the command to be " "run to check the status of a real server. It should exit with status 0 if " "everything\n" "is ok, or non-zero otherwise.\n" "
Four parameters are passed to the script:\n" "
check port = n\n" "
Number of port to monitor. Sometimes check port differs from service " "port.\n" "
Default: port specified for each real server\n" "\n" "\n" "
request = \"uri to requested object\"\n" "
This object will be requested each checkinterval seconds on each real " "server. The string must be inside quotes. Note that this string may be " "overridden by\n" "an optional per real-server based request-string.\n" "
For a DNS check this should the name of an A record, " "or the address of a PTR record to look up.\n" "
For a MySQL, Oracle or PostgeSQL check, this should be an SQL query. The data returned is not checked, only that the answer is one " "or more\n" "rows. This is a required setting.\n" "
For a simpletcp check, this string is sent verbatim except any " "occurances of \n" " are replaced with a new line character.\n" "\n" "\n" "
receive = \"regexp to compare\"\n" "
If the requested result contains this regexp to compare, the " "real server is declared alive. The regexp must be inside quotes. Keep in " "mind that\n" "regexps are not plain strings and that you need to escape the special " "characters if they should as literals. Note that this regexp may be " "overridden by an\n" "optional per real-server based receive regexp.\n" "
For a DNS check this should be any one the A record's " "addresses or any one of the PTR record's names.\n" "
For a MySQL check, the receive setting is not used.\n" "\n" "\n" "
http method = GET | HEAD\n" "
Sets the HTTP method which should be used to fetch the " "URI specified in the request-string. GET is " "the\n" "method used by default if the parameter is not set. If HEAD " "is used, the receive-string should be unset.\n" "
Default: GET\n" "\n" "\n" "
virtual host = \"hostname\"\n" "
Used when using a negotiate check with HTTP or " "HTTPS . Sets the host header used in the HTTP " "request. In the\n" "case of HTTPS this generally needs to match the common name " "of the SSL certificate. If not set then the host header will " "be\n" "derived from the request url for the real server if present. As a last " "resort the IP address of the real server will be used.\n" "\n" "\n" "
login = \"username\"\n" "
For FTP , IMAP , LDAP , " "MySQL, Oracle, POP and PostgreSQL, the username used to log " "in.\n" "
For Radius the passwd is used for the attribute User-Name.\n" "
For SIP , the username is used as both the to and from " "address for an OPTIONS query.\n" "
Default:\n" "
Password to use to login to FTP , IMAP , " "LDAP , MySQL, Oracle, POP , PostgreSQL and\n" "SIP servers.\n" "
For Radius the passwd is used for the attribute User-Password.\n" "
Default:\n" "
Database to use for MySQL, Oracle and PostgreSQL servers, this is the " "database that the query (set by receive above) will be performed " "against. This\n" "is a required setting.\n" "\n" "\n" "
radius secret = \"radiussecret\"\n" "
Secret to use for Radius servers, this is the secret used to perform " "an Access-Request with the username (set by login above) and passwd " "(set by\n" "passwd above).\n" "
Default: empty string\n" "\n" "\n" "
persistent = n\n" "
Number of seconds for persistent client connections.\n" "\n" "\n" "
netmask = w.x.y.z\n" "
Netmask to be used for granularity of persistent client connections.\n" "\n" "\n" "
scheduler = scheduler_name\n" "
Scheduler to be used by LVS for loadbalancing. For an " "information on the available sehedulers please see the ipvsadm(8) man page.\n" "
Default: \"wrr\"\n" "\n" "\n" "
protocol = tcp|udp|fwm\n" "
Protocol to be used. If the virtual is specified as an IP address and port then it must be one of tcp or udp. If a firewall " "mark then the\n" "protocol must be fwm.\n" "
Default:\n" "

使用 checktype=negotiate 時要監控的服務類型。None 表示不監控服務。\n" "
如果指定 simpletcp，則會將 request 字串傳送到伺服器，並根據 " "receive regexp 測試該伺服器。其他類型的檢查將使用指定的\n" "通訊協定連接至伺服器。如需通訊協定特定的資訊，請參閱 request 和 " "receive 部分。\n" "
預設值：\n" "
如果 checktype 為 external 並且是檢查真實伺服器狀態時要執行的指令，則會使" "用此設定。如果一切正常，則此指令將結束並傳回\n" "狀態 0，否則傳回非零值。\n" "

預設值：為每個真實伺服器指定的連接埠\n" "\n" "\n" "
request = \"所要求物件的 URI\"\n" "
在每個真實伺服器上每隔 checkinterval 指定秒數將要求此物件一次。必須將" "該字串括在引號中。請注意，此字串可能會被基於每個真實伺服器\n" "的可選 request 字串覆寫。\n" "
對於 DNS 檢查，此字串應為 A 記錄的名稱，或是要查詢的 " "PTR 記錄的位址。\n" "
對於 MySQL、Oracle 或 PostgeSQL 檢查，此字串應為 SQL 查" "詢。不會檢查傳回的資料，回應為一列或\n" "多列。這是必要的設定。\n" "
對於 simpletcp 檢查，將逐字傳送此字串，不過，出現的所有 \n" " 都將以換行字元取代。\n" "\n" "\n" "
receive = \"要比較的 regexp\"\n" "
如果要求的結果中包含這個要比較的 regexp，則會將真實伺服器宣告為" "使用中。必須將該 regexp 括在引號中。請記住，\n" "regexp 不是純文字字串，對於應視為文字字串的特殊字元，您需要進行逸出處理。請注" "意，此 regexp 可能會被基於每個真實伺服器\n" "的可選 receive regexp 覆寫。\n" "
對於 DNS 檢查，此 regexp 應為任一 A 記錄的位址，或任一 " "PTR 記錄的名稱。\n" "
對於 MySQL 檢查，不使用 receive 設定。\n" "\n" "\n" "
http method = GET | HEAD\n" "
設定要用於擷取 request 字串中指定之 URI 的 " "HTTP 方法。如果未設定該參數，將依預設\n" "使用 GET 方法。如果使用 HEAD，應取消設定 " "receive 字串。\n" "
預設值：GET\n" "\n" "\n" "
virtual host = \"hostname\"\n" "
將 negotiate check 與 HTTP 或 HTTPS 結合" "使用時使用。設定 HTTP 要求中使用的主機標頭。對於\n" "HTTPS，這通常需要與 SSL 證書的公用名稱相符。如" "果不設定此參數，則會從真實伺服器\n" "的要求 URL (如果存在) 中衍生。最終補救方法是使用真實伺服器的 IP 位址。\n" "\n" "\n" "
login = \"username\"\n" "
對於 FTP、IMAP、LDAP、" "MySQL、Oracle、POP 和 PostgreSQL，此為用於登入的使用者名稱。\n" "

預設值：\n" "
用於 MySQL、Oracle 和 PostgreSQL 伺服器的資料庫，此為要對其執行查詢 (由上" "面的 receive 設定) 的資料庫。這是\n" "必要的設定。\n" "\n" "\n" "
radius secret = \"radiussecret\"\n" "
用於 Radius 伺服器的密碼，此密碼用於結合 username (由上面的 login 設定) 和 passwd (由上面的\n" "passwd 設定) 執行Access-Request。\n" "
預設值：空字串\n" "\n" "\n" "
persistent = n\n" "
永久用戶端連接的秒數。\n" "\n" "\n" "

此為用於指定永久用戶端連接粒度的網路遮罩。\n" "\n" "\n" "
scheduler = scheduler_name\n" "
LVS 用來進行負載平衡的規劃程式。如需可用規劃程式的資" "訊，請參閱 ipvsadm(8) 手冊頁。\n" "
預設值：wrr\n" "\n" "\n" "
protocol = tcp|udp|fwm\n" "
要使用的通訊協定。如果將虛擬指定為 IP 位址和連接埠，則" "該值必須是 tcp 或 udp。如果指定為防火牆標記，則\n" "protocol 必須是 fwm。\n" "
預設值：\n" "
check timeout = n\n" "
connect、external 和 ping 檢查的逾時秒數。如果超過該逾時，則宣告真實伺" "服器不存在。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "
如果未定義，則會使用 negotiatetimeout 的值。negotiatetimeout 全域值也" "有可能會被 per-virtual 設定覆寫。\n" "
如果 checktimeout 和 negotiatetimeout 都未設定，則會使用預設值。\n" "
預設值：5 秒\n" "\n" "
negotiate timeout = n\n" "
協商檢查的逾時秒數。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "
如果未定義，則會使用 connecttimeout 的值。connecttimeout 全域值也有可" "能會被 per-virtual 設定覆寫。\n" "
如果 negotiatetimeout 和 connecttimeout 都未設定，則會使用預設值。\n" "
預設值：30 秒\n" "\n" "
failure count = n\n" "
此為在將真實伺服器視為故障伺服器前，檢查必須報告的連續失敗次數。如果值" "為 1，則表示第一次失敗後即將真實伺服器視為有故障。檢查成功之後，會將失敗計數" "器重設為 0。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "
預設值：1\n" "\n" "
email alert = \"emailaddress\"\n" "
此為一個有效的電子郵件地址，用於將連接狀態已變更的警示傳送到虛擬服務中" "定義的任何真實伺服器。此選項要求安裝 perl\n" "模組 MailTools。它會自動嘗試使用任一內建方法傳送電子郵件。如需方法的更多資" "訊，請參閱「perldoc Mail::Mailer」。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "\n" "
email alert freq = n\n" "
此為當虛擬服務中的任一指定真實伺服器保持不可存取狀態時，兩次重複傳送電" "子郵件警示之間的延遲秒數。設定為零秒則表示\n" "禁止重複傳送警示。此設定的電子郵件計時準確性視乎 checkinterval 組態選項中定義" "的\n" "秒數而定。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "
預設值：0\n" "\n" "
email alert status = all|none|starting|running|stopping|reloading,...\n" "
此為伺服器狀態的逗號分隔清單，進入該狀態時，應傳送電子郵件警示。" "all 是\n" "「starting,running,stopping,reloading」的簡寫。如" "果指定 none，則不能指定其他任何選項，否則，將由指定的其他選項\n" "決定是否傳送。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "

fallback = ip_address|hostname[:portnumber|" "sercvicename] [gate|masq|ipip]\n" "
此為當所有真實伺服器已關閉時，將 Web 服務重新導向到的伺服器。通常是 " "127.0.0.1 以及一個緊急頁面。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "\n" "
quiescent = yes|no\n" "
如果為 yes，則當判定真實伺服器或後援伺服器關閉時，不會真正將其" "從核心的 LVS 表中移除，\n" "而是會將其權數設定為零，即表示將不接受任何新的連接。\n" "
這會導致一個副作用，即，如果真實伺服器具有永久連接，則來自任何現有用戶" "端的新連接將繼續路由到\n" "真實伺服器，直到永久逾時過期。如需永久連接的更多資訊，請參閱「ipvsadm」。\n" "
可透過執行以下指令避免這種副作用：\n" "
echo 1 > /proc/sys/net/ipv4/vs/expire_quiescent_template\n" "
如果 proc 檔案不存在，則可能意味著核心不提供 lvs 支援、未載入 " "LVS 支援，或者核心太舊\n" "未包含 proc 檔案。在可能的情況下，以 root 身分執行 ipvsadm 應該可以將 " "LVS 載入核心。\n" "
如果為 no，則會從核心的 LVS 表中移除真實伺服器或" "錯誤回復伺服器。預設值為 yes。\n" "
如果在虛擬伺服器區段中定義該值，則會覆寫全域值。\n" "
