场景：rpm包安装的nginx服务，无法满足定制模块的需求，故线上环境使用nginx源码进行安装。本片文章详细介绍如何使用saltstack的配置管理功能实现nginx软件的源码安装。
下载源码:pcre
http://exim.mirror.fr/pcre/pcre-8.38.tar.gz
下载源码:nginx
http://nginx.org/download/nginx-1.9.12.tar.gz
1.修改master配置文件,指定环境为prod。
[root@node1 prod]# egrep -A 6 ^file_roots /etc/salt/master file_roots: base: - /srv/salt/base dev: - /srv/salt/dev prod: - /srv/salt/prod
2.编写state文件，最终的目录树如下所示：
[root@node1 prod]# tree .├── initpkg│ └── install.sls├── nginx│ ├── files│ │ ├── nginx│ │ └── nginx-1.9.12.tar.gz│ └── install.sls├── pcre│ ├── files│ │ └── pcre-8.38.tar.gz│ └── install.sls└── top.sls5 directories, 7 files
3.state文件的详细内容如下：
[root@node1 prod]# cat initpkg/install.sls init-pkg-install: pkg.installed: - names: - gcc - gcc-c++ - make - autoconf - openssl - openssl-devel - lsof - tree - lrzsz[root@node1 prod]# cat pcre/install.sls include: - initpkg.installpcre-source-install: file.managed: - name: /usr/local/src/pcre-8.38.tar.gz - source: salt://pcre/files/pcre-8.38.tar.gz - user: root - group: root - mode: 755 cmd.run: - name: cd /usr/local/src && tar xf pcre-8.38.tar.gz && cd pcre-8.38 && ./configure --prefix=/usr/local/pcre && make && make install - unless: test -d /usr/local/pcre - reuqire: - file: pcre-source-install[root@node1 prod]# cat nginx/install.sls include: - initpkg.install - pcre.installnginx-source-install: file.managed: - name: /usr/local/src/nginx-1.9.12.tar.gz - source: salt://nginx/files/nginx-1.9.12.tar.gz - user: root - group: root - mode: 755 cmd.run: - name: cd /usr/local/src && tar xf nginx-1.9.12.tar.gz && cd nginx-1.9.12 && ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-file-aio --with-http_dav_module --with-pcre=/usr/local/src/pcre-8.38 && make && make install - unless: test -d /usr/local/nginx - require: - file: nginx-source-install - pkg: init-pkg-install - file: pcre-source-installnginx-init: file.managed: - name: /etc/init.d/nginx - source: salt://nginx/files/nginx - user: root - group: root - mode: 755 cmd.run: - name: chkconfig --add nginx - unless: chkconfig --list |grep nginx - reuqire: - cmd: nginx-source-install - file: nginx-initnginx-service: service.running: - name: nginx - enable: nginx - reload: true - require: - cmd: nginx-init[root@node1 prod]# cat top.sls prod: 'node2.xkops.com': - nginx.install - pcre.install - initpkg.install
4.执行state模块在node2.xkopa.com客户端源码安装nginx。
[root@node1 prod]# salt '*' state.highstate env=prod test[root@node1 prod]# salt '*' state.highstate env=prod5.在node2检查客户端是否完成nginx安装
[root@node2 ~]# service nginx status 提示：此处列出的为state文件的编写内容，记得查看一下tree的结果，在pcre和nginx目录下还各自有files目录，存放着pcre-8.38.tar.gz、nginx-1.9.12.tar.gz源码包以及nginx启动服务脚本文件。
