Jenkins + Ansible + Gitlab 自动化部署三剑客

Gitlab

准备linux初始环境

# 关闭防火墙
systemctl stop firewalld
# 开机自动关闭
systemctl disable firewalld
# 强制关闭selinux
vim /etc/sysconfig/selinux
SELINUX=disabled
# 查看selinux策略是否被禁用（Disabled）
getenforce
# 安装gitlab依赖包
yum install -y curl policycoreutils openssh-server openssh-clients postfix git
# 下载gitlab yum仓库源
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
# 启动postfix邮件服务
systemctl start postfix
systemctl enable postfix
# 安装gitlab
yum install -y gitlab-ce

# 手动配置ssl证书
mkdir -p /etc/gitlab/ssl
openssl genrsa -out "/etc/gitlab/ssl/gitlab.example.com.key" 2048
cd /etc/gitlab/ssl
openssl req -new -key "/etc/gitlab/ssl/gitlab.example.com.key" -out "/etc/gitlab/ssl/gitlab.example.com.csr"
# 进入ssl安装向导
cn (country)
bj (province)
bj (city)
空格 (organization)
空格 (organization unit)
gitlab.example.com (common name gitlab域名)
[email protected] (email)
1234qwer (证书密码)
空格 (company name)
# /etc/gitlab/ssl 目录下可以看到密钥和csr证书
# 利用ssl密钥和证书创建签署crt证书
openssl x509 -req -days 365 -in "/etc/gitlab/ssl/gitlab.example.com.csr" -signkey "/etc/gitlab/ssl/gitlab.example.com.key" -out "/etc/gitlab/ssl/gitlab.example.com.crt"
# 利用openssl签署pem证书
openssl dhparam -out /etc/gitlab/ssl/dhparams.pem  2048
# 更改ssl下的所有证书权限
chmod 600 *

# 配置证书到gitlab配置文件中
vim /etc/gitlab/gitlab.rb 
external_url 'https://gitlab.example.com'
nginx['redirect_http_to_https'] = true (去掉注释)
nginx['ssl_certificate'] = "/etc/gitlab/ssl/gitlab.example.com.crt" (注释不去掉)
nginx['ssl_certificate_key'] = "/etc/gitlab/ssl/gitlab.example.com.key" (注释不去掉)
nginx['ssl_dhparam'] = /etc/gitlab/ssl/dhparams.pem (注释不去掉)
# 初始化gitlab相关服务配置
gitlab-ctl reconfigure 
# 找到gitlab下的ningx反向代理工具, 更改gitlab的http配置文件
vim /var/opt/gitlab/nginx/conf/gitlab-http.conf
# 在 server_name 下面一行添加如下，用来重定向所有getlab的http请求
rewrite ^(.*)$ https://$host$1 permanent;
gitlab-ctl restart
# 即可访问服务器地址访问gitlab页面，在主机添加dns

gitlab-ctl reconfigure 错误：

运存必须大于2GB

如果卡在 ruby_block[wait for postgresql service socket] action run 长时间不动

退出配置 另一个终端开启 /opt/gitlab/embedded/bin/runsvdir-start

然后重新 gitlab-ctl reconfigure

如果卡在 bash[migrate gitlab-rails database] action run 长时间不动 或者如下错误

bash[migrate gitlab-rails database] (gitlab::database_migrations line 55) had an error: Mixlib::Shel

解决办法 :

gitlab-ctl stop

chmod 755 /var/opt/gitlab/postgresql

另一个终端开启 systemctl restart gitlab-runsvdir

gitlab-ctl reconfigure

gitlab-ctl restart

搭建Gitlab仓库

# 在gitlab页面建好第一个项目
# 登录gitlab主界面，添加一个New project，输入 Project name 和 Project description，Visibility Level 选择默认 Private，创建好后复制仓库http地址 COPY URL
# 回到服务器，在用户下创建 repo目录
mkdir repo
cd repo
# 这里的 -c http.sslVerify=false 用来避免本地证书无法进行clone操作，如果没有添加dns，则直接访问ip/root/test-repo.git 输入用户名和密码
git -c http.sslVerify=false clone https://gitlab.example.com/root/test-repo.git
vim test.py print "This is test code"
# 添加test.py到本地仓库
git add . 
# 提交
git commit -m"First commit"
# 提示创建本地git全局的邮箱和用户名，再次运行 git commit -m"First commit" 即可提交成功
git config --global user.email "[email protected]"
git config --global user.name "admin"
# 输入账号密码，同步本地master分支到远程服务器当中
git -c http.sslVerify=false push origin master

# 查看当前全局用户配置
git config --global --list
# 创建代码分支release-1.0
git checkout -b release-1.0
# 修改代码
vim test.py print "This is test code for release-1.0"
# 添加修改
git add .
# 提交
git commit -m"release-1.0"
#  输入账号密码，同步本地release-1.0分支到远程服务器当中
git -c http.sslVerify=false push origin release-1.0

完全卸载删除gitlab

# 停止gitlab
gitlab-ctl stop
# 卸载gitlab（注意这里写的是gitlab-ce）
rpm -e gitlab-ce
# 查看gitlab进程
ps aux | grep gitlab
# 杀掉第一个进程（就是带有好多.............的进程）
kill -9 18777
# 杀掉后，在ps aux | grep gitlab确认一遍，还有没有gitlab的进程
# 删除所有包含gitlab文件
find / -name gitlab | xargs rm -rf

Ansible

安装与配置

# 关闭防火墙
systemctl stop firewalld
# 开机自动关闭
systemctl disable firewalld
# 强制关闭selinux
vim /etc/sysconfig/selinux
SELINUX=disabled
# 查看selinux策略是否被禁用（Disabled）
getenforce

# 安装Python和pip
yum -y install git nss curl wget libffi-devel openssl-devel
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tgz
tar -zxvf Python-3.8.0.tgz
cd Python-3.8.0
# --with-ensurepip 用来安装 pip 包管理工具，--enable-shared LDFLAGS 配置python 匹配当前系统的参数值
./configure --prefix=/usr/local/python3 --enable-optimizations --with-ssl
make && make install

# 安装python虚拟环境
pip3 install virtualenv
# 在新用户下创建 virtualenv
useradd deploy
su - deploy
virtualenv -p /usr/local/bin/python3.8 .py3-a2.5-env

# git 拉取Ansible源码
git clone https://github.com/ansible/ansible.git
# 加载virtualenv环境
source /home/deploy/.py3-a2.5-env/bin/activate
# 安装ansible依赖包
pip3 install paramiko PyYAML jinja2
# 把ansible源代码移动到python3.6的virtualenv环境下
mv ansible .py3-a2.5-env/
cd .py3-a2.5-env/ansible/
# 切换到ansible到2.5版本
git checkout stable-2.5
# 加载
source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q
# 看是否安装成功
ansible-playbook --version

pip3 安装包时报错ModuleNotFoundError: No module named '_ctypes'的解决办法

pip3 install时报错“pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

yum install libffi-devel 重新编译安装python3

如果安装完jinja2后还是出现 No module named jinja2， 可以直接yum安装 yum install -y python-jinja2 python-yaml

playbooks 测试 (需要先配置好服务器和部署主机的ssh无密码访问)

# 加载virtualenv环境
source /home/deploy/.py3-a2.5-env/bin/activate
# 加载ansible
source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q
# 验证是否开启ansible服务
ansible-playbook --version
# 创建如下目录结构
(py3-a2.5-env) [root@k8s-master test_playbooks]# tree .
.
├── deploy.yml
├── inventory
│   └── testenv
└── roles
    └── testbox
        └── tasks
            └── main.yml

4 directories, 3 files

# inventory 为Server详细清单目录，里面存放具体清单与变量声明文件，用于保存目标部署主机的相关域名和ip地址以及变量参数
# roles 为详细任务列表目录，里面存放一个或者多个 role，通常被命名为具体的APP或者项目名称，这里命名为 testbox 作为项目名称，下面的 tasks 目录用来保存 testbox 主任务文件 main.yml，deploy.yml 作为 playbook 任务入口文件，将调度 roles 下需要部署的项目，以及该项目下的所有任务，最终将该任务部署在 inventory 下定义的目标主机中

vim testenv

[testservers]
test.example.com

[testservers:vars]
server_name=test.example.com
user=root
output=/root/test.txt

# [testservers] 为 Server 组列表，下面包含目标部署服务器的主机名，可以是域名也可以是ip地址
# [testservers:vars] 为 testservers 组的列表参数，下面包含该组下的目标主机需要的 Key/value 键值对参数

vim main.yml

- name: Print server name and user to remote testbox
  shell: "echo 'Currently {{ user }} is logining {{ server_name}}' > {{ output}}" 
  
# name 为任务名称，方便知道该 task 是做什么用的
# shell 为使用shell模块执行命令，双括号里为引入 testenv 中的 [testservers:vars] 参数

vim deploy.yml

- hosts: "testservers" # 对应 testenv 中的 server 标签，调用该标签下的目标主机
  gather_facts: true  # 获取目标主机下的信息
  remote_user: root   # 在目标主机下使用root权限
  roles:
    - testbox        # 进入目标下的testbox目录

# ansible 核心文件，与 ansible-playbook 命令直接对话
# 执行部署
ansible-playbook -i inventory/testenv ./deploy.yml

Ansible Playbooks 常用模块应用

# File模块  创建文件或目录，并赋予系统权限
- name: create a file
  file: 'path=/root/foo.txt state=touch mode=0775 owner=foo group=foo'
# 实现Ansible服务端到目标主机的文件传送 force=yes 强制执行
- name: copy a file
  copy: 'remote_src=no src=roles/testbox/files/foo.sh dest=/root/foo.sh mode=0644 force=yes'
# Stat模块 获取远程文件状态信息 register: script_stat 把状态信息赋值给script_stat 变量
- name: check if foo.sh exists
  stat: 'path=/root/foo.sh'
  register: script_stat
# Debug模块 打印语句到Ansible执行输出 debug: msg=foo.sh exists 表示输出信息为foo.sh exists
- debug: msg="foo.sh exists"
  when: script_stat.stat.exists
# Command/Shell模块 用来执行Linux目标主机命令行 shell会调用linux下的bin/bash，就可以使用系统环境变量、重定向符、管道符等
- name: run the script
  command: "sh /root/foo.sh"
- name: run the script
  shell: "echo 'test' > /root/test.txt"
# Template模块 实现Ansible服务端到目标主机的jinja2模板传送 nginx.conf.j2中的变量参数会调用server清单里的var变量参数值
- name: write the nginx config file
  template: src=roles/testbox/templates/nginx.conf.j2 dest=/etc/nginx/nginx.conf
# Packaging模块 调用目标主机系统包管理工具（yum,apt）进行安装 yum包装目标系统为CentOS/Redhat，apt则为Debian/Ubuntu
- name: ensure nginx is at the latest version
  yum: pkg=nginx state=latest
- name: ensure nginx is at the latest version
  apt: pkg=nginx state=latest
# Service模块 管理目标主机系统服务
- name: start nginx service
  service: name=nginx state=started

注意 commond 模块和 shell 模块类似，但有区别

command 模块命令将不会使用 shell 执行. 因此, 像 $HOME 这样的变量是不可用的。还有像<, >, |, ;, &都将不可用。

shell 模块通过shell程序执行， 默认是/bin/sh, <, >, |, ;, & 可用。但这样有潜在的 shell 注入风险， 后面会详谈.

command 模块更安全，因为他不受用户环境的影响。 也很大的避免了潜在的 shell 注入风险.

register 是将该模块执行后的输出写入到变量，变量的命名不能用 -中横线，比如dev-sda6_result，则会被解析成sda6_result，dev会被丢掉，所以不要用 - 。全局变量或者 role 下的vars 变量也不要用 -

ignore_errors这个关键字很重要，一定要配合设置成True，否则如果命令执行不成功，即 echo $?不为0，则在其语句后面的ansible语句不会被执行，导致程序中止。

; By default the status page output is formatted as text/plain. Passing either

;   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

;   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;

;   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

;                          because memory calculation is done when the request

;  %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 %{}t tag

; The log file for slow requests
; Default Value: not 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

; 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

; 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. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. 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 [email protected]
;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
