Gitlab+Jenkins学习之路（十四）之自动化脚本部署实践

一、环境说明和准备

1、环境说明

主机名	IP地址	角色	系统
deploy-server	192.168.56.12	发布	Centos 7.4
web	192.168.56.13	web服务器，nfs服务器	Centos 7.4

2、服务器准备工作

（1）发布机前期准备

a.增加普通用户并配置密码

[root@deploy-server ~]# useradd www
[root@deploy-server ~]# id www
uid=1000(www) gid=1000(www) groups=1000(www)
[root@deploy-server ~]# passwd www
[root@deploy-server ~]# yum install -y git tree

[root@deploy-server ~]# mkdir -pv /deploy/{code/{www,jxs,wap,gys,glzx,yyzx},config,tar,tmp}
[root@deploy-server ~]# chown -R www.www /deploy
[www@deploy-server ~]$ tree /deploy
/deploy
├── code
│   ├── glzx
│   ├── gys
│   ├── jxs
│   ├── wap
│   ├── www
│   └── yyzx
├── config
├── tar
└── tmp
[www@deploy-server ~]$ cd /deploy/code/www && git init

c.创建配置文件config.php

[www@deploy-server ~]$ vim /deploy/config/config.php 
this is config.php
[www@deploy-server ~]$ tree /deploy
/deploy
├── code
│   ├── glzx
│   ├── gys
│   ├── jxs
│   ├── wap
│   ├── www
│   └── yyzx
├── config
│   └── config.php
├── tar
└── tmp

d.配置发布机和目标机的ssh通信

[www@deploy-server deploy]$ cat /home/www/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDzM3AW6/X+djvKJTsdFbY3ik+mlradxpD3COoTP5h6x509unksuCdduV7awPjEGHvK2GVjJmvckxdvLkMc23p7bsctHlturPN2VozJTrYwXMAbmxf97cKE/fpKhjPXG8HlWBLpEaTM8PITgvdcyaeAUaIN+/h5VrA8TZKFAgbxDLxtgwqPzYIG9nqCO7MMCgzhJxI6PDQ6KVU9rHal/p4XKTIy4Rq4FzZTav2tS4zNJ7kX9+e6EO0JTooPanJXBTltLOJJsKxnlA7tc20rq6+0XVqbUBKYahL/8ZzkxZozNrNq7wtIuuJo0WTDFzDdPcJyAGlRWLuwct7y4p4UApVz www@deploy-server

[www@deploy-server ~]$ ssh-copy-id www@192.168.56.13
/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/www/.ssh/id_rsa.pub"

www@192.168.56.13's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'www@192.168.56.13'"
and check to make sure that only the key(s) you wanted were added.

[www@deploy-server ~]$ ssh 192.168.56.13
Last login: Fri Nov  2 18:01:02 2018
[www@web ~]$

e.将ssh公钥复制到github或gitlab

（2）web服务器准备

a.部署NFS服务器

[root@web ~]# yum install -y nfs-utils rpcbind
[root@web ~]# vim /etc/exports
/nas/www 192.168.56.0/24(rw,sync,no_root_squash)
/nas/jxs 192.168.56.0/24(rw,sync,no_root_squash)
/nas/wap 192.168.56.0/24(rw,sync,no_root_squash)
/nas/glzx 192.168.56.0/24(rw,sync,no_root_squash)
/nas/yyzx 192.168.56.0/24(rw,sync,no_root_squash)
/nas/gys 192.168.56.0/24(rw,sync,no_root_squash)
[root@web ~]# systemctl start rpcbind
[root@web ~]# systemctl start nfs
[root@web ~]# showmount -e
Export list for web:
/nas/gys  192.168.56.0/24
/nas/yyzx 192.168.56.0/24
/nas/glzx 192.168.56.0/24
/nas/wap  192.168.56.0/24
/nas/jxs  192.168.56.0/24
/nas/www  192.168.56.0/24

b.挂载共享目录

[root@web ~]# mkdir /webroot/{www,jxs,wap,gys,glzx,yyzx}
[root@web ~]# chown -R www.www /webroot
[root@web ~]# mount -f nfs 192.168.56.13:/nas/www /webroot/www
[root@web ~]# df -h
Filesystem               Size  Used Avail Use% Mounted on

192.168.56.13:/nas/www    18G  1.7G   16G  10% /webroot/www

c.部署nginx+php

[root@web ~]# useradd www
[root@web ~]# passwd www
[root@web ~]# yum install -y nginx php php-fpm
[root@web ~]# vim /etc/nginx/nginx.conf
user www;
worker_processes auto;
error_log /var/log/nginx/error.log;

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;


}
[root@web ~]# mkdir /data/web -pv && chown -R www.www /data
[root@web ~]# vim /etc/nginx/nginx.conf
server {
        listen 80;
        server_name  localhost;

        root /data/web/www;
        index index.php index.htm index.html;
        client_max_body_size 20m;
        location / {
                proxy_read_timeout 150;
                try_files $uri $uri/ /index.php;
        }

        location ~* .*.php$ {
                #try_files     $uri =404;
                include fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_split_path_info       ^(.+.php)(/.+)$;
                fastcgi_param PATH_INFO       $fastcgi_path_info;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }
}
[root@web ~]# nginx -t

二、发布脚本编写

1、自动化部署流程设计

发布机获取代码（直接拉取），从svn或git仓库进行拉取
发布机编译代码（可选，java语言需要编译，PHP无需编译）
将配置文件拷贝到代码文件（由于配置文件有数据库等机密信息，需要独立处理）
代码打包（将代码进行压缩打包）
SCP到目标服务器目录
将目标服务器移除集群
在目标服务器上进行解压传过来的代码
解压后，对代码根目录进行软链接到刚才的目录文件，实现版本链接
重启（可选，tomcat需要重启）
测试
加入集群

2、自动化部署脚本编写

#!/bin/bash

#deploy-server create dir as root
#[ -d /deploy ] && mkdir -pv /deploy/{code/web-demo,config,tar,tmp} && chown -R www.www /deploy

#node-server create dir as root
#[ -d /data ] && mkdir -pv /data/web && chown -R www.www /data
#nfs dir /nas/www mount to /webroot

useage(){
    echo $"Useage: $0 { deploy |rollback [ list | version ] }"
}

url_test(){
    URL=$1
    curl -s --head $URL |grep '200 OK'
    if [ $? -ne 0 ];then
    	shell_unlock;
    	writelog "test error" && exit;
    fi
}

writelog(){
    LOGINFO=$1
    echo "${CDATE} ${CTIME}: ${SHELL_NAME} : ${LOGINFO} " >> ${SHELL_LOG}
}

code_get(){
	writelog "code_get";
	cd ${CODE_DIR} && git pull git@github.com:kin08200/learngit.git
	cp -r ${CODE_DIR} ${TMP_DIR}
	API_VERL=$(git show |grep commit |cut -d ' ' -f2 )
    	API_VER=$(echo ${API_VERL:0:6})
	echo $API_VER
}

code_config(){
	writelog "code_config"
	/bin/cp -r ${CONFIG_DIR}/* ${TMP_DIR}/${PRO_NAME}
    	PKG_NAME=${PRO_NAME}_"${API_VER}"_"${CDATE}-${CTIME}"
    	cd ${TMP_DIR} && mv ${PRO_NAME} ${PKG_NAME}
}

	ssh $NODE "cd /webroot/www && tar -zxf ${PKG_NAME}.tar.gz"
	ssh $NODE "rm -rf /data/web/www && ln -s /webroot/www/${PKG_NAME} /data/web/www"
}

code_test(){
	url_test "http://192.168.56.13"
}

rollback_fun(){
	ssh $NODE "rm -rf /data/web/www && ln -s /webroot/www/$1 /data/web/www"   
}

rollback(){
	if [ -z $1 ];then
    	shell_unlock;
        echo "Please input rollback version." && exit;
    	fi
    	case $1 in 
    	    list)
