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 (/).

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.

Defining 'disable_functions' or 'disable_classes' will not ; overwrite previously defined php.ini values, but will append the new value ; instead. ; Default Value: nothing is defined by default except the values in php.ini and ; specified at startup with the -d argument ;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com ;php_flag[display_errors] = off php_admin_value[error_log] = /var/log/php-fpm/www-error.log php_admin_flag[log_errors] = on ;php_admin_value[memory_limit] = 128M ; Set session path to a directory owned by process user php_value[session.save_handler] = files php_value[session.save_path] = /var/lib/php/session php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache

(正常情况下)稍等片刻之后就会看到“SUCCESS”(注意首次构建可能会提示“No such property: deploy_env for class: groovy.lang.Binding”)遇到这个错误，只需返回到word press-pipeline-job工程点击“Build with Parameters”选择默认dev用户再次构建即可。
（纸上得来终觉浅，绝知此事要躬行，真的是各种采坑）久违的“SUCCESS”

至此，使用Jenkins+Gitlab+Ansible自动化部署wordpresss全部完成。
接下来说说注意点，尽量避免以后重蹈覆辙：
第一次没有上传Wordpress-project仓库，也没有配置test.example.com主机上的/etc/hosts文件，导致在部署过程中一直卡在某个环节不动，或者直接提示

错误信息5
这个报错是在错误信息4之前，因为test.example.com主机没有git命令所以才有了错误信息4的步骤
TASK [wordpress : Close git ssl verification] ********************************** fatal: [test.example.com]: FAILED! => {"changed": true, "cmd": "git config --global http.sslVerify false", "delta": "0:00:00.002747", "end": "2019-01-10 18:00:36.334202", "msg": "non-zero return code", "rc": 127, "start": "2019-01-10 18:00:36.331455", "stderr": "/bin/sh: git: command not found", "stderr_lines": ["/bin/sh: git: command not found"], "stdout": "", "stdout_lines": []} to retry, use: --limit @/var/lib/jenkins/workspace/wordpress-pipeline-job/wordpress_playbooks/deploy.retry
错误信息6
这个变量没有在deploy.yml中定义，所以会抛出异常解决办法就是在deploy.yml中声明以下backup_to
TASK [wordpress : Backup current www folder] *********************************** fatal: [test.example.com]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'backup_to' is undefined\n\nThe error appears to have been in '/var/lib/jenkins/workspace/wordpress-pipeline-job/wordpress_playbooks/roles/wordpress/tasks/main.yml': line 53, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Backup current www folder\n ^ here\n"} to retry, use: --limit @/var/lib/jenkins/workspace/wordpress-pipeline-job/wordpress_playbooks/deploy.retry
deploy.yml中添加颜色加重部分
- hosts: wordpress gather_facts: true remote_user: root vars: backup_to: "{{root}}_{{branch}}_{{ansible_date_time.epoch}}" roles: - wordpress
解决过程中还遇到一个git提交错误
