user = deploy
; RPM: Keep a group allowed to write in log dir.
group = deploy
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen = /var/run/php-fpm/php-fpm.sock
; Set listen(2) backlog.
; Default Value: 511 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 511
; Set permissions for unix socket, if one is used. 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

; 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. With this process management, there will be
; always at least 1 children.
; pm.max_children - the maximum number of children that can
; be alive at the same time.
; pm.start_servers - the number of children created on startup.
; pm.min_spare_servers - the minimum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is less than this
; number then some children will be created.
; pm.max_spare_servers - the maximum number of children in 'idle'
; state (waiting to process). If the number
; of 'idle' processes is greater than this
; number then some children will be killed.
; ondemand - no children are created at startup. Children will be forked when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
; This value sets the limit on the number of simultaneous requests that will be
; served. 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'

; 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.

;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:

- 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
#!groovy
pipeline {
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 $deploy_env"
source /home/deploy/.py3-a2.8-env/bin/activate
source /home/deploy/.py3-a2.8-env/ansible/hacking/env-setup -q
echo "[INFO] Current python version"
python --version
echo "[INFO] Current ansible version"
ansible-playbook --version
echo "[INFO] Remote system disk space"
ssh [email protected] df -h
echo "[INFO] Remote system RAM"
ssh [email protected] free -m
else
echo "Deployment user is incorrect, please check"
fi
set -x
"""
}
}
}
stage("Ansible deployment") {
steps {
input "Do you approve the deployment?"
dir ("${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123456
New 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 -p123456
MariaDB [(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。
