; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;

; Example output:
;   pool:                 www
;   process manager:      static
;   start time:           01/Jul/2011:17:53:49 +0200

;
; 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.

;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

7、配置main.yml

qiufeng.li@DESKTOP-JC7QDVB MINGW64 ~/ansible-playbook-repo/wordpress_playbooks (main)
$ vim roles/wordpress/tasks/main.yml- name: Update yum dependencyshell: 'yum update -y warn=False'- name: Disable system firewallservice: name=firewalld state=stopped- name: Disable SELINXselinux: state=disabled- name: Setup epel yum source for nginx and mariadb(mysql)yum: pkg=epel-release state=latest- name: Setup webtatic yum source for php-fpmyum: name=https://mirror.webtatic.com/yum/el7/webtatic-release.rpm- name: Ensure nginx is at the latest versionyum: pkg=nginx state=latest- name: Write the nginx config filetemplate: src=roles/wordpress/templates/nginx.conf.j2 dest=/etc/nginx/nginx.conf- name: Create nginx root folderfile: 'path={{ root }} state=directory owner={{ user }} group={{ user }} mode=0755'- name: Copy info.php to remotecopy: 'remote_src=no src=roles/wordpress/files/info.php dest=/data/www/info.php mode=0755'- name: Restart nginx serviceservice: name=nginx state=restarted- name: Setup php-fpmcommand: 'yum install -y php70w php70w-fpm php70w-common php70w-mysql php70w-gd php70w-xml php70w-mbstring php70w-mcrypt warn=False'- name: Restart php-fpm serviceservice: name=php-fpm state=restarted- name: Copy php-fpm config file to remotecopy: 'remote_src=no src=roles/wordpress/files/www.conf dest=/etc/php-fpm.d/www.conf mode=0755 owner={{ user }} group={{ user }} force=yes'- name: Restart php-fpm serviceservice: name=php-fpm state=restarted- name: Run the health check locallyshell: "sh roles/wordpress/files/health_check.sh {{ server_name }} {{ port }}"delegate_to: localhostregister: health_status- debug: msg="{{ health_status.stdout }}"- name: Setup mariadb(mysql)command: "yum install -y mariadb mariadb-server warn=False"- name: Backup current www foldershell: 'mv {{ root }} {{ backup_to }}'- name: Close git ssl verificationshell: 'git config --global http.sslVerify false'- name: Clone WordPress repo to remotegit: "repo=https://{{ gitlab_user | urlencode }}:{{ gitlab_pass | urlencode }}@gitlab.example.com/root/Wordpress-project.git dest=/data/www version={{ branch }}"when: project == 'wordpress'- name: Change www folder permissionfile: "path=/data/www mode=0755 owner={{ user }} group={{ user }}"

8、配置nginx.conf.j2

Luoyi@Mr_Eden MINGW64 ~/Desktop/repo/ansible-playbook-repo/wordpress_playbooks (master)
$ vim roles/wordpress/templates/nginx.conf.j2
# For more information on configuration, see:
user              {{ user }};
worker_processes  {{ worker_processes }};  error_log  /var/log/nginx/error.log;  pid        /var/run/nginx.pid;  events {  worker_connections  {{ max_open_file }};

9、提交代码到 gitlab

qiufeng.li@DESKTOP-JC7QDVB MINGW64 ~/ansible-playbook-repo/wordpress_playbooks (main)
$ pwd

10、gitlab 查看确认

11、创建 Wordpress 项目

创建Wordpress-project仓库
下载 wordpress 项目文件解压(wordpress官网下载项目包)
提交wordpress 项目代码到 gitlab

qiufeng.li@DESKTOP-JC7QDVB MINGW64 ~

四、jenkins 自动部署 wordpress

登录到 Jenkins web 管理页
点击“New 任务”

添加描述

输入 pipeline 脚本
pipeline script脚本内容（注意credentialsId要查看本地设置的凭据中的ID，复制过来替换掉即可）

# 虚拟 ansibel 环境脚本
#!groovypipeline {agent {node {label 'master'}}environment {PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"}parameters {choice(choices: 'dev\nrprod',description: 'Choose deploy environment',name: 'deploy_env')string (name: 'branch', defaultValue: 'master', description: 'Fill in your ansible repo branch')}stages {stage ("Pull deploy code") {steps{sh 'git config --global http.sslVerify false'dir ("${env.WORKSPACE}"){git branch: 'master', credentialsId: '2e6fa379-1a4b-4e0c-8075-efeb7ffb530e', url: 'https://gitlab.example.com/root/ansible-playbook-repo.git'}}}stage ("Check env") {steps {sh """set +xuser=`whoami`if [ $user == deploy ]thenecho "[INFO] Current deployment user is $user"source /home/deploy/.py3-a2.9-env/bin/activatesource /home/deploy/.py3-a2.9-env/ansible/hacking/env-setup -qecho "[INFO] Current python version"python --versionecho "[INFO] Current ansible version"ansible-playbook --versionecho "[INFO] Remote system disk space"ssh root@test.example.com df -hecho "[INFO] Rmote system RAM"ssh root@test.example.com free -melseecho "Deployment user is incorrect, please check"fiset -x"""}}stage ("Anisble deployment") {steps {input "Do you approve the deployment?"dir("${env.WORKSPACE}/wordpress_playbooks"){echo "[INFO] Start deployment"sh """set +xsource /home/deploy/.py3-a2.9-env/bin/activatesource /home/deploy/.py3-a2.9-env/ansible/hacking/env-setup -qansible-playbook -i inventory/$deploy_env ./deploy.yml -e project=wordpress -e branch=$branch -e env=$deploy_envset -x"""echo "[INFO] Deployment finished..."}}}}}# pip 安装 ansible 脚本
#!groovypipeline {agent {node {label 'master'}}environment {PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin"}parameters {choice(choices: 'dev\nrprod',description: 'Choose deploy environment',name: 'deploy_env')string (name: 'branch', defaultValue: 'master', description: 'Fill in your ansible repo branch')}stages {stage ("Pull deploy code") {steps{sh 'git config --global http.sslVerify false'dir ("${env.WORKSPACE}"){git branch: 'master', credentialsId: 'gitlab-root', url: 'https://gitlab.example.com/root/ansible-playbook-repo.git'}}}stage ("Check env") {steps {sh """set +xuser=`whoami`if [ $user == deploy ]thenecho "[INFO] Current deployment user is $user"echo "[INFO] Current python version"/usr/local/bin/python3 --versionecho "[INFO] Current ansible version"/usr/local/bin/ansible-playbook --versionecho "[INFO] Remote system disk space"ssh root@test.example.com df -hecho "[INFO] Rmote system RAM"ssh root@test.example.com free -melseecho "Deployment user is incorrect, please check"fiset -x"""}}stage ("Anisble deployment") {steps {input "Do you approve the deployment?"dir("${env.WORKSPACE}/wordpress_playbooks"){echo "[INFO] Start deployment"sh """set +x/usr/local/bin/ansible-playbook -i inventory/$deploy_env ./deploy.yml -e project=wordpress -e branch=$branch -e env=$deploy_envset -x"""echo "[INFO] Deployment finished..."}}}}}

注意：填写 credentialsId 字段的凭据id
获取凭据ID

点击查看输出信息

(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。

最后需要利用git bash或者Mobaterm登录test.example.com主机上初始化MySQL数据库，（实际生产环境中不建议使用Jenkins重复构建初始化MySQL数据库，容易出现各种问题）

[root@test ~]# systemctl status mariadb
● mariadb.service - MariaDB database serverLoaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled; vendor preset: disabled)Active: inactive (dead)
[root@test ~]# systemctl start mariadb
[root@test ~]# mysql_secure_installationNOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDBSERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.Enter current password for root (enter for none):   #mariadb5.5首次安装没有root密码，所以直接回车即可
OK, successfully used password, moving on...Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.Set root password? [Y/n] y
New password:   #1234.com
Re-enter new password:
Password updated successfully!
Reloading privilege tables..... Success!By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.Remove anonymous users? [Y/n] y... Success!Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.Disallow root login remotely? [Y/n] y... Success!By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.Remove test database and access to it? [Y/n] y- Dropping test database...... Success!- Removing privileges on test database...... Success!Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.Reload privilege tables now? [Y/n] y... Success!Cleaning up...All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.Thanks for using MariaDB!

创建wordpress数据库

[root@test www]# mysql -uroot -p1234.com
