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+). Makes sense only with a tcp listening socket. Each address ; must be separated by a comma. If this value is left blank, connections will be ; accepted from any ip address. ; Default Value: any listen.allowed_clients = 127.0.0.1 ; Specify the nice(2) priority to apply to the pool processes (only if set) ; The value can vary from -19 (highest priority) to 20 (lower priority) ; Note: - It will only work if the FPM master process is launched as root ; - The pool processes will inherit the master process priority ; unless it specified otherwise ; Default Value: no set ; process.priority = -19 ; Choose how the process manager will control the number of child processes. ; Possible Values: ; static - a fixed number (pm.max_children) of child processes; ; dynamic - the number of child processes are set dynamically based on the ; following directives.

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: @EXPANDED_DATADIR@/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.

- pipeline job构建与自动化部署:
点击新建任务
,任务名称输入wordpress-pipeline-job
,选择流水线
。
添加描述信息:This is my first wordpress pipeline job
,
接着定义Pipeline script
,写入下面内容
#!groovypipeline { agent {node {label 'master'}} environment { PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin" } parameters { choice ( choices: 'dev\nprod', description: 'choose deploy environment', name: 'deploy_env' ) string ( name: 'branch', defaultValue: 'master', description: 'build branch' ) } stages { stage("Pull deploy code") { steps { sh 'git config --global http.sslVertify false' dir ("${env.WORKSPACE}") { git branch: 'master', credentialsId: "00ee2c7c-c475-440c-a88f-dd6c9a49f669", url: 'https://gitlab.lzxlinux.com/root/ansible-playbook-repo.git' } } } stage("Check env") { steps { dir ("${env.WORKSPACE}") { sh """ set +x user=`whoami` if [ $user == deploy ] then echo "Current deployment environment is $deploy_env" source /home/deploy/.py3-a2.8-env/bin/activate source /home/deploy/.py3-a2.8-env/ansible/hacking/env-setup -q echo "[INFO] Current python version" python --version echo "[INFO] Current ansible version" ansible-playbook --version echo "[INFO] Remote system disk space" ssh root@test.lzxlinux.com df -h echo "[INFO] Remote system RAM" ssh root@test.lzxlinux.com free -m else echo "Deployment user is incorrect, please check" fi set -x """ } } } stage("Ansible deployment") { steps { input "Do you approve the deployment?" dir ("${env.WORKSPACE}/wordpress_playbooks") { echo "[INFO] Start deployment" sh """ set +x source /home/deploy/.py3-a2.8-env/bin/activate source /home/deploy/.py3-a2.8-env/ansible/hacking/env-setup -q ansible-playbook -i inventory/$deploy_env ./deploy.yml -e project=wordpress -e branch=$branch -e env=$deploy_env set -x """ echo "[INFO] Deployment finished..." } } } }}
上面的credentialsId即00ee2c7c-c475-440c-a88f-dd6c9a49f669
,是复制凭据页面创建该凭据(gitlab管理员全局凭据)时自动生成的凭据id。
点击应用
,再点击保存
。接着点击立即构建
,等待构建完成,会发现构建失败,原因是第一次构建时选项参数
没有引入到当前的pipeline job中。
点击wordpress-pipeline-job
回到该项目中,会发现立即构建
变成了Build with Parameters
,选择对应的选项参数
,选择好后点击开始构建
。
等待构建完成,查看控制台输出
- 创建数据库wordpress:
# systemctl start mariadb.service# mysql_secure_installation Enter current password for root (enter for none): #直接回车Set root password? [Y/n] y #设置root密码,我这里是123456New password: Re-enter new password: Remove anonymous users? [Y/n] y #删除匿名用户Disallow root login remotely? [Y/n] y #不允许root用户远程登录Remove test database and access to it? [Y/n] y #删除test database及其访问Reload privilege tables now? [Y/n] y #重载所有权限
# mysql -uroot -p123456MariaDB [(none)]> create database wordpress character set utf8;
打开浏览器,访问test.lzxliux.com:8080
(如果deploy_env
选择的是prod
,则访问test.lzxliux.com
)。
点击现在就开始
,填入数据库root用户及其密码,点击提交
。
接着填入站点标题、管理员用户及其密码等信息,点击安装WordPress
。
接着使用上面定义的管理员用户及其密码登录wordpress后台管理界面。
使用pipeline job自动化部署wordpress的过程到此成功结束。
