Install error about mcrouter

[alikhtarov]

@mosesgumi Did you use the provided install scripts? Could you share the details of your operating system (distribution/version)?

[mosesgumi]

it is working now, but i have to call the mcrouter this way

webapp@ip-10-11-13-50:~$ ~/mcrouter-install/install/bin/mcrouter --help
mcrouter 1.0
usage: /home/webapp/mcrouter-install/install/bin/mcrouter [options] -p port(s) -f config

libmcrouter options:

Startup
--asynclog-disable disable async log file spooling
-a, --async-dir container directory for async storage spools [default: "/var/spool/mcrouter"]
--use-asynclog-version2 Enable using the asynclog version 2.0
--num-proxies adjust how many proxy threads to run [default: 1]
--disable-priorities don't use event base priorities
--no-realtime when run as root, mcrouter is run with realtime priority to improve latency. Use this option to disable realtime-priority when run as root
--big-value-split-threshold If 0, big value route handle is not part of route handle tree,else used as threshold for splitting big values internally [default: 0]
--fibers-max-pool-size Maximum number of preallocated free fibers to keep around [default: 1000]
--fibers-stack-size Size of stack in bytes to allocate per fiber. 0 means use fibers library default. [default: (16 * 1024)]
--fibers-debug-record-stack-size Record exact amount of fibers stacks used (expensive: debug only!)
--runtime-vars-file Path to the runtime variables file. [default: ""]
--file-observer-poll-period-ms How often to check inotify for updates on the tracked files. [default: 100]

Network
-K, --keepalive-count set TCP KEEPALIVE count, 0 to disable [default: 0]

-I, --keepalive-idle set TCP KEEPALIVE idle parameter in seconds [default: 300]
--reset-inactive-connection-interval Will close open connections without any activity after at most 2 * interval ms. If value is 0, connections won't be closed. [default: 60000]
--tcp-rto-min adjust the minimum TCP retransmit timeout (ms) to memcached [default: -1]
--target-max-inflight-requests Maximum inflight requests allowed per target per thread (0 means no throttling) [default: 0]
--target-max-pending-requests Only active if target-max-inflight-requests is nonzero. Hard limit on the number of requests allowed in the queue per target per thread. Requests that would exceed this limit are dropped immediately. [default: 100000]
--target-max-shadow-requests Hard limit on the number of shadow requests allowed in the queue per target per thread. Requests that would exceed this limit are dropped immediately. [default: 1000]
--no-network Debug only. Return random generated replies, do not use network.
--proxy-max-inflight-requests If non-zero, sets the limit on maximum incoming requests that will be routed in parallel by each proxy thread. Requests over limit will be queued up until the number of inflight requests drops. [default: 0]
--proxy-max-throttled-requests Only active if proxy-max-inflight-requests is non-zero. Hard limit on the number of requests to queue per proxy after there are already proxy-max-inflight-requests requests in flight for the proxy. Further requests will be rejected with an error immediately. 0 means disabled. [default: 0]
--pem-cert-path Path of pem-style certificate for ssl [default: ""]
--pem-key-path Path of pem-style key for ssl [default: ""]
--pem-ca-path Path of pem-style CA cert for ssl [default: ""]

--group-remote-errors Groups all remote (i.e. non-local) errors together, returning a single result for all of them: mc_res_remote_error
--upgrading-l1-exptime 0 means that we will use the L2 exptime. Otherwise, when upgrading this value is used as the exptime for all requests [default: 0]
--send-invalid-route-to-default Send request to default route if routing prefix is not present in config
--enable-flush-cmd Enable flush_all command

TKO probes
--disable-tko-tracking Disable TKO tracker (marking a host down for fast failover after a number of failures, and sending probes to check if the server came back up).
-r, --probe-timeout-initial TKO probe retry initial timeout in ms [default: 10000]
--probe-timeout-max TKO probe retry max timeout in ms [default: 60000]
--timeouts-until-tko Mark as TKO after this many failures [default: 3]
--maximum-soft-tkos The maximum number of machines we can mark TKO if they don't have a hard failure. [default: 40]
--latency-window-size The number of samples to track when computing moving average latency for a proxy destination. [default: 16]

Timeouts
-t, --server-timeout server timeout in ms (DEPRECATED try to use cluster-server-timeout and regional-server-timeout) [default: 1000]

--regional-pools-timeout server timeout for regional pools in ms. Default value 0 means using deprecated server-timeout value for the flag [default: 0]
--cross-region-timeout-ms Timeouts for talking to cross region pool. If specified (non 0) takes precedence over every other timeout. [default: 0]

--within-cluster-timeout-ms Timeouts for talking to pools within same cluster. If specified (non 0) takes precedence over every other timeout. [default: 0]
--same-connection-any-timeout If enabled - same connection to a destination may be used for requests with different timeouts.

Logging
--stats-root Root directory for stats files [default: "/var/mcrouter/stats"]
--stats-logging-interval Time in ms between stats reports, or 0 for no logging [default: 10000]
--logging-rtt-outlier-threshold-us surpassing this threshold rtt time means we will log it as an outlier. 0 (the default) means that we will do no logging of outliers. [default: 0]

--max-client-outstanding-reqs Maximum requests outstanding per client (0 to disable) [default: (uint32_t)((1024 * 1024 * 100) / (3 * 1024))]
--reqs-per-read Adjusts server buffer size to process this many requests per read. Smaller values may improve latency. [default: 0]

Misc options:
--proxy-threads Like --num-proxies, but also accepts 'auto' to start one thread per core
-D, --debug-level set debug level
-d, --debug increase debug level (may repeat)
-h, --help help
-V, --version version
-v, --verbose verbose
--validate-config Check config and exit immediately with good or error status

RETURN VALUE
2 On a problem that might be resolved by restarting later.
3 On a problem that will definitely not be resolved by restarting.

is there a way to call mcrouter --help instead??

[alikhtarov]

The simplest way is to just add ~/mcrouter-install/install/bin/ to your PATH variable:

export PATH=~/mcrouter-install/install/bin/:$PATH

Alternatively you can add a symlink to e.g. /usr/bin:

sudo ln -s ~/mcrouter-install/install/bin/mcrouter /usr/bin/mcrouter
(you probably want absolute path instead of ~ here).

[mosesgumi]

Ok done. Thanks. can close the issue
