持续集成 - 发布系统

发布系统在技术团队中有着重要作用, 承担我们每天的服务部署工作, 企业发布系统根据企业技术能力来决定, 小公司不像那些公司一样,有充足的人力去开发一套自己的发布系统. 所以尽可能的去寻找一些适合企业应用的部署系统, 以提高人力成本.

这里推荐两款开源的发布系统:

jekins: https://jenkins.io/ (Java语言开发)[普遍]
walle: http://www.walle-web.io/ (PHP语言开发)[小众]

jekins可能大家都很熟悉,也有好多文章, walle是国人写的一个轻量的发布系统, 只所以推荐它是因为相对其它开源的发布系统来说, 其UI界面至少看着比较舒服, 基本功能也都有. 支持国产开源.

Walle安装部署

Walle是基于PHP写的, 所以安装前需要安装PHP环境.

PHP环境安装

这里选用php最新稳定版7.1.10

[root@localhost ~]# wget http://cn2.php.net/distributions/php-7.1.10.tar.gz
[root@localhost ~]# tar -zxvf php-7.1.10.tar.gz 
[root@localhost ~]# cd php-7.1.10/
[root@localhost php-7.1.10]# ./configure --help
[root@localhost php-7.1.10]# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel
[root@localhost php-7.1.10]# ./configure --prefix=/usr/local/php \
 --with-curl \
 --with-freetype-dir \
 --with-gd \
 --with-gettext \
 --with-iconv-dir \
 --with-kerberos \
 --with-libdir=lib64 \
 --with-libxml-dir \
 --with-mysqli \
 --with-openssl \
 --with-pcre-regex \
 --with-pdo-mysql \
 --with-pdo-sqlite \
 --with-pear \
 --with-png-dir \
 --with-xmlrpc \
 --with-zlib \
 --enable-fpm \
 --enable-bcmath \
 --enable-libxml \
 --enable-inline-optimization \
 --enable-gd-native-ttf \
 --enable-mbregex \
 --enable-mbstring \
 --enable-pcntl \
 --enable-shmop \
 --enable-soap \
 --enable-sockets \
 --enable-sysvsem \
 --enable-xml \
 --enable-zip
 [root@localhost php-7.1.10]# make & make install
 [root@localhost php-7.1.10]# cp php.ini-development /usr/local/php/lib/php.ini
[root@localhost php-7.1.10]# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
[root@localhost php-7.1.10]#  cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
[root@localhost php-7.1.10]# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm
[root@localhost php-7.1.10]# /etc/init.d/php-fpm

修改php进程归属用户(/usr/local/php/etc/php-fpm.d/www.conf), 修改user和group值.
笔者示例中值均为 elonsu.

[elonsu@localhost ~]$ grep -C 3 'elonsu' /usr/local/php/etc/php-fpm.d/www.conf -n
20-; Unix user/group of processes
21-; Note: The user is mandatory. If the group is not set, the default user's group
22-;       will be used.
23:user = elonsu
24:group = elonsu
25-
26-; The address on which to accept FastCGI requests.
27-; Valid syntaxes are:

配置php环境变量

在/etc/profile文件末尾追加环境变量,如下:

# 这是PHP环境变量
PHP_HOME=/usr/local/php
# 设置Meven环境变量
M2_HOME=/usr/local/apache-maven-3.5.0
# 设置Java环境变量
JAVA_HOME=/usr/local/jdk1.8.0_121
JRE_HOME=/usr/local/jdk1.8.0_121/jre
CLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib
PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$M2_HOME/bin:$PHP_HOME/bin:

export PHP_HOME M2_HOME JAVA_HOME JRE_HOME CLASS_PATH PATH

使配置生效

[root@localhost ~]$ source /etc/profile
[elonsu@localhost ~]$ php -v

远程GIT仓库授权配置

远程私有仓库ssh 授权

[elonsu@localhost ~]#  ssh-keygen -t rsa -C "dennisit@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/elonsu/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /elonsu/.ssh/id_rsa.
Your public key has been saved in /elonsu/.ssh/id_rsa.pub.
The key fingerprint is:
8b:8a:a0:b3:a5:a1:5f:96:8a:3c:5a:c1:e0:b3:f4:f3 dennisit@163.com
The key's randomart image is:
+--[ RSA 2048]----+

[elonsu@localhost ~]# ls 
[elonsu@localhost ~]$ ls ~/.ssh/
id_rsa  id_rsa.pub

这里的id_rsa为私钥, id_rsa_pub为公钥

Git服务器配置SSH公钥

以开源中国为例, 【个人】-【设置】-【SSH公钥】

开源中国官方配置说明:http://git.mydoc.io/?t=154712

检测配置

[elonsu@localhost ~]$ ssh -T git@gitee.com

部署目标机器授权

我们以root用户身份, 将项目发布到192.178.0.107服务上时,需要给目标机器授权.如下:

1	[root@localhost ~]$ ssh-copy-id -i ~/.ssh/id_rsa.pub root@192.168.0.107

此时会提示让输入目标服务器密码. 正确输入密码后,配置成功.
