In Linux, read/write ; permissions must be set in order to allow connections from a web server. Many ; BSD-derived systems allow connections regardless of permissions. ; Default Values: user and group are set as the running user ; mode is set to 0660 listen.owner = deploy listen.group = deploy ;listen.mode = 0660 ; When POSIX Access Control Lists are supported you can set them using ; these options, value is a comma separated list of user/group names. ; When set, listen.owner and listen.group are ignored ;listen.acl_users = ;listen.acl_groups = ; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect. ; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original ; PHP FCGI (5.2.2+).

Equivalent to the ApacheMaxClients directive with mpm_prefork. ; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP ; CGI. ; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand' ; Note: This value is mandatory. pm.max_children = 50 ; The number of child processes created on startup. ; Note: Used only when pm is set to 'dynamic' ; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2 pm.start_servers = 5 ; The desired minimum number of idle server processes. ; Note: Used only when pm is set to 'dynamic' ; Note: Mandatory when pm is set to 'dynamic' pm.min_spare_servers = 5 ; The desired maximum number of idle server processes. ; Note: Used only when pm is set to 'dynamic' ; Note: Mandatory when pm is set to 'dynamic' pm.max_spare_servers = 35 ; The number of seconds after which an idle process will be killed. ; Note: Used only when pm is set to 'ondemand' ; Default Value: 10s ;pm.process_idle_timeout = 10s; ; The number of requests each child process should execute before respawning. ; This can be useful to work around memory leaks in 3rd party libraries. For ; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS. ; Default Value: 0 ;pm.max_requests = 500 ; The URI to view the FPM status page. If this value is not set, no URI will be ; recognized as a status page. It shows the following informations: ; pool - the name of the pool; ; process manager - static, dynamic or ondemand; ; start time - the date and time FPM has started; ; start since - number of seconds since FPM has started; ; accepted conn - the number of request accepted by the pool; ; listen queue - the number of request in the queue of pending ; connections (see backlog in listen(2)); ; max listen queue - the maximum number of requests in the queue ; of pending connections since FPM has started; ; listen queue len - the size of the socket queue of pending connections; ; idle processes - the number of idle processes; ; active processes - the number of active processes; ; total processes - the number of idle + active processes; ; max active processes - the maximum number of active processes since FPM ; has started; ; max children reached - number of times, the process limit has been reached, ; when pm tries to start more children (works only for ; pm 'dynamic' and 'ondemand'); ; Value are updated in real time. ; Example output: ; pool: www ; process manager: static ; start time: 01/Jul/2011:17:53:49 +0200 ; start since: 62636 ; accepted conn: 190460 ; listen queue: 0 ; max listen queue: 1 ; listen queue len: 42 ; idle processes: 4 ; active processes: 11 ; total processes: 15 ; max active processes: 12 ; max children reached: 0 ; ; By default the status page output is formatted as text/plain. Passing either ; 'html', 'xml' or 'json' in the query string will return the corresponding ; output syntax. Example: ; http://www.foo.bar/status ; http://www.foo.bar/status?json ; http://www.foo.bar/status?html ; http://www.foo.bar/status?xml ; ; By default the status page only outputs short status. Passing 'full' in the ; query string will also return status for each pool process. ; Example: ; http://www.foo.bar/status?full ; http://www.foo.bar/status?json&full ; http://www.foo.bar/status?html&full ; http://www.foo.bar/status?xml&full ; The Full status returns for each process: ; pid - the PID of the process; ; state - the state of the process (Idle, Running, ...); ; start time - the date and time the process has started; ; start since - the number of seconds since the process has started; ; requests - the number of requests the process has served; ; request duration - the duration in µs of the requests; ; request method - the request method (GET, POST, ...); ; request URI - the request URI with the query string; ; content length - the content length of the request (only with POST); ; user - the user (PHP_AUTH_USER) (or '-' if not set); ; script - the main script called (or '-' if not set); ; last request cpu - the %cpu the last request consumed ; it's always 0 if the process is not in Idle state ; because CPU calculation is done when the request ; processing has terminated; ; last request memory - the max amount of memory the last request consumed ; it's always 0 if the process is not in Idle state ; because memory calculation is done when the request ; processing has terminated; ; If the process is in Idle state, then informations are related to the ; last request the process has served. Otherwise informations are related to ; the current request being served. ; Example output: ; ************************ ; pid: 31330 ; state: Running ; start time: 01/Jul/2011:17:53:49 +0200 ; start since: 63087 ; requests: 12808 ; request duration: 1250261 ; request method: GET ; request URI: /test_mem.php?N=10000 ; content length: 0 ; user: - ; script: /home/fat/web/docs/php/test_mem.php ; last request cpu: 0.00 ; last request memory: 0 ; ; Note: There is a real-time FPM status monitoring sample web page available ; It's available in: @[email protected]/fpm/status.html ; ; Note: The value must start with a leading slash (/). The value can be ; anything, but it may not be a good idea to use the .php extension or it ; may conflict with a real PHP file. ; Default Value: not set ;pm.status_path = /status ; The ping URI to call the monitoring page of FPM. If this value is not set, no ; URI will be recognized as a ping page. This could be used to test from outside ; that FPM is alive and responding, or to ; - create a graph of FPM availability (rrd or such); ; - remove a server from a group if it is not responding (load balancing); ; - trigger alerts for the operating team (24/7). ; Note: The value must start with a leading slash (/). The value can be ; anything, but it may not be a good idea to use the .php extension or it ; may conflict with a real PHP file. ; Default Value: not set ;ping.path = /ping ; This directive may be used to customize the response of a ping request. The ; response is formatted as text/plain with a 200 response code. ; Default Value: pong ;ping.response = pong ; The access log file ; Default: not set ;access.log = log/$pool.access.log ; The access log format. ; The following syntax is allowed ; %%: the '%' character ; %C: %CPU used by the request ; it can accept the following format: ; - %{user}C for user CPU only ; - %{system}C for system CPU only ; - %{total}C for user + system CPU (default) ; %d: time taken to serve the request ; it can accept the following format: ; - %{seconds}d (default) ; - %{miliseconds}d ; - %{mili}d ; - %{microseconds}d ; - %{micro}d ; %e: an environment variable (same as $_ENV or $_SERVER) ; it must be associated with embraces to specify the name of the env ; variable. Some exemples: ; - server specifics like: %{REQUEST_METHOD}e or %{SERVER_PROTOCOL}e ; - HTTP headers like: %{HTTP_HOST}e or %{HTTP_USER_AGENT}e ; %f: script filename ; %l: content-length of the request (for POST request only) ; %m: request method ; %M: peak of memory allocated by PHP ; it can accept the following format: ; - %{bytes}M (default) ; - %{kilobytes}M ; - %{kilo}M ; - %{megabytes}M ; - %{mega}M ; %n: pool name ; %o: output header ; it must be associated with embraces to specify the name of the header: ; - %{Content-Type}o ; - %{X-Powered-By}o ; - %{Transfert-Encoding}o ; - .... ; %p: PID of the child that serviced the request ; %P: PID of the parent of the child that serviced the request ; %q: the query string ; %Q: the '?' character if query string exists ; %r: the request URI (without the query string, see %q and %Q) ; %R: remote IP address ; %s: status (response code) ; %t: server time the request was received ; it can accept a strftime(3) format: ; %d/%b/%Y:%H:%M:%S %z (default) ; The strftime(3) format must be encapsuled in a %{<strftime_format>}t tag ; e.g. for a ISO8601 formatted timestring, use: %{%Y-%m-%dT%H:%M:%S%z}t ; %T: time the log has been written (the request has finished) ; it can accept a strftime(3) format: ; %d/%b/%Y:%H:%M:%S %z (default) ; The strftime(3) format must be encapsuled in a %{<strftime_format>}t tag ; e.g. for a ISO8601 formatted timestring, use: %{%Y-%m-%dT%H:%M:%S%z}t ; %u: remote user ; ; Default: "%R - %u %t \"%m %r\" %s" ;access.format = "%R - %u %t \"%m %r%Q%q\" %s %f %{mili}d %{kilo}M %C%%" ; The log file for slow requests ; Default Value: not set ; Note: slowlog is mandatory if request_slowlog_timeout is set slowlog = /var/log/php-fpm/www-slow.log ; The timeout for serving a single request after which a PHP backtrace will be ; dumped to the 'slowlog' file. A value of '0s' means 'off'. ; Available units: s(econds)(default), m(inutes), h(ours), or d(ays) ; Default Value: 0 ;request_slowlog_timeout = 0 ; The timeout for serving a single request after which the worker process will ; be killed. This option should be used when the 'max_execution_time' ini option ; does not stop script execution for some reason. A value of '0' means 'off'. ; Available units: s(econds)(default), m(inutes), h(ours), or d(ays) ; Default Value: 0 ;request_terminate_timeout = 0 ; Set open file descriptor rlimit. ; Default Value: system defined value ;rlimit_files = 1024 ; Set max core size rlimit. ; Possible Values: 'unlimited' or an integer greater or equal to 0 ; Default Value: system defined value ;rlimit_core = 0 ; Chroot to this directory at the start. This value must be defined as an ; absolute path. When this value is not set, chroot is not used. ; Note: chrooting is a great security feature and should be used whenever ; possible. However, all PHP paths will be relative to the chroot ; (error_log, sessions.save_path, ...). ; Default Value: not set ;chroot = ; Chdir to this directory at the start. ; Note: relative path can be used. ; Default Value: current directory or / when chroot ;chdir = /var/www ; Redirect worker stdout and stderr into main error log. If not set, stdout and ; stderr will be redirected to /dev/null according to FastCGI specs. ; Note: on highloaded environement, this can cause some delay in the page ; process time (several ms). ; Default Value: no ;catch_workers_output = yes ; Clear environment in FPM workers ; Prevents arbitrary environment variables from reaching FPM worker processes ; by clearing the environment in workers before env vars specified in this ; pool configuration are added. ; Setting to "no" will make all environment variables available to PHP code ; via getenv(), $_ENV and $_SERVER. ; Default Value: yes ;clear_env = no ; Limits the extensions of the main script FPM will allow to parse. This can ; prevent configuration mistakes on the web server side. You should only limit ; FPM to .php extensions to prevent malicious users to use other extensions to ; exectute php code. ; Note: set an empty value to allow all extensions. ; Default Value: .php ;security.limit_extensions = .php .php3 .php4 .php5 .php7 ; Pass environment variables like LD_LIBRARY_PATH.

(正常情況下)稍等片刻之後就會看到“SUCCESS”(注意首次構建可能會提示“No such property: deploy_env for class: groovy.lang.Binding”)遇到這個錯誤，只需返回到word press-pipeline-job工程點選“Build with Parameters”選擇預設dev使用者再次構建即可。
（紙上得來終覺淺，絕知此事要躬行，真的是各種採坑）久違的“SUCCESS”

最後需要利用git bash或者xshell登入test.example.com主機上初始化MySQL資料庫，（實際生產環境中不建議使用Jenkins重複構建初始化MySQL資料庫，容易出現各種問題）

至此，使用Jenkins+Gitlab+Ansible自動化部署wordpresss全部完成。
接下來說說注意點，儘量避免以後重蹈覆轍：
