SaltStack--項目實戰
saltstack項目實戰
項目架構規劃
後端web服務器使用Nginx+Php做爲站點，經過HAproxy作負載均衡，Keepalived作高可用php
項目環境準備
說明： 關閉防火牆、selinux、時間同步等html
host綁定mysql
[root@salt-master ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.1.30 salt-master 192.168.1.31 salt-minion01 192.168.1.32 salt-minion02 192.168.1.33 salt-minion03 192.168.1.34 salt-minion04 [root@salt-master ~]# for i in `seq 4`; do scp /etc/hosts 192.168.1.3$i:/etc/hosts ; done
軟件安裝
參考地址linux
1）Master上軟件安裝nginx
[root@salt-master ~]# yum -y install https://mirrors.aliyun.com/saltstack/yum/redhat/salt-repo-latest-2.el7.noarch.rpm [root@salt-master ~]# sed -i "s/repo.saltstack.com/mirrors.aliyun.com\/saltstack/g" /etc/yum.repos.d/salt-latest.repo [root@salt-master ~]# yum -y install salt-master [root@salt-master ~]# systemctl enable salt-master [root@salt-master ~]# systemctl start salt-master
2）Minion上軟件安裝並配置c++
# yum -y install https://mirrors.aliyun.com/saltstack/yum/redhat/salt-repo-latest-2.el7.noarch.rpm # yum -y install salt-minion # cp /etc/salt/minion{,.back} # sed -i '/#master: /c\master: salt-master' /etc/salt/minion # systemctl enable salt-minion # systemctl start salt-minion
Master上認證
[root@salt-master ~]# systemctl restart salt-master [root@salt-master ~]# salt-key -L Accepted Keys: Denied Keys: Unaccepted Keys: salt-minion01 salt-minion02 salt-minion03 salt-minion04 Rejected Keys: [root@salt-master ~]# salt-key -A -y The following keys are going to be accepted: Unaccepted Keys: salt-minion01 salt-minion02 salt-minion03 salt-minion04 Key for minion salt-minion01 accepted. Key for minion salt-minion02 accepted. Key for minion salt-minion03 accepted. Key for minion salt-minion04 accepted. [root@salt-master ~]# salt-key -L Accepted Keys: salt-minion01 salt-minion02 salt-minion03 salt-minion04 Denied Keys: Unaccepted Keys: Rejected Keys: [root@salt-master ~]# salt '*' test.ping salt-minion01: True salt-minion02: True salt-minion03: True salt-minion04: True
Master上state編寫
state環境設置
說明：該案例在prod環境下配置，在prod下面建立了一個modules的目錄，全部的安裝配置都放在這個目錄下面了，裏面分別又對應建立了對應的軟件目錄，每一個軟件目錄下面的files目錄用來存放的是軟件包或者配置文件模板web
[root@salt-master ~]# vim /etc/salt/master file_roots: base: - /srv/salt/base test: - /srv/salt/test prod: - /srv/salt/prod dev: - /srv/salt/dev [root@salt-master ~]# systemctl restart salt-master [root@salt-master ~]# mkdir -p /srv/salt/{base,test,prod,dev} [root@salt-master ~]# mkdir -p /srv/salt/prod/modules/{nginx,php,mysql,haproxy,keepalived,lnmp}/files [root@salt-master ~]# mkdir /srv/salt/prod/modules/user [root@salt-master ~]# tree /srv/salt/prod/modules/ /srv/salt/prod/modules/ ├── haproxy │ └── files ├── keepalived │ └── files ├── lnmp │ └── files ├── mysql │ └── files ├── nginx │ └── files ├── php │ └── files └── user 13 directories, 0 files

測試lnmp是否OK
1）Top file編寫
[root@salt-master ~]# cat /srv/salt/base/top.sls prod: "salt-minion0[3-4]": - modules.lnmp.www
2）執行高級狀態
[root@salt-master ~]# salt '*' state.highstate

3）service.sls
[root@salt-master haproxy]# cat service.sls #引入haproxy安裝的sls include: - modules.haproxy.install #配置文件 haproxy-config: file.managed: - name: /etc/haproxy/haproxy.cfg - source: salt://modules/haproxy/files/haproxy.cfg - user: root - group: root - mode: 644 - require: - pkg: haproxy-install #啓動haproxy haproxy-service: service.running: - name: haproxy - enable: True - require: - pkg: haproxy-install - file: haproxy-config - watch: - file: haproxy-config
keepalived
1）配置文件準備
[root@salt-master ~]# cd /srv/salt/prod/modules/keepalived/ [root@salt-master keepalived]# tree . ├── files │ └── keepalived.conf ├── install.sls └── service.sls 1 directory, 3 files
2）install.sls
[root@salt-master keepalived]# cat install.sls keepalived-install: pkg.installed: - name: keepalived
3）service.sls
[root@salt-master keepalived]# cat service.sls #引入keepalived安裝的sls include: - modules.keepalived.install #keepalived配置文件 keepalived-config: file.managed: - name: /etc/keepalived/keepalived.conf - source: salt://modules/keepalived/files/keepalived.conf - user: root - group: root - mode: 644 - require: - pkg: keepalived-install - template: jinja - defaults: {% if grains['fqdn'] == "salt-minion01" %} ROUTER_ID: saltstack01 STATE: MASTER PRIORITY: 150 {% elif grains['fqdn'] == "salt-minion02" %} ROUTER_ID: saltstack02 STATE: BACKUP PRIORITY: 100 {% endif %} #啓動keepalived keepalived-service: service.running: - name: keepalived - enable: True - require: - pkg: keepalived-install - file: keepalived-config - watch: - file: keepalived-config
總體部署
1）top file 編寫
[root@salt-master ~]# cat /srv/salt/base/top.sls prod: "salt-minion0[3-4]": - modules.lnmp.www "salt-minion0[1-2]": - modules.haproxy.service - modules.keepalived.service
2）高級狀態執行
[root@salt-master ~]# salt '*' state.highstate
3）測試
訪問192.168.1.31和192.168.1.32的狀態頁
訪問VIP192.168.1.100
經過上面測試可看到能夠成功訪問lnmp站點，而且haproxy也ok。訪問全部四臺服務器均可以獲得phpinfo頁面，而在生產環境中，咱們只是對外提供vip便可。
項目總結
1）總體環境查看
[root@salt-master ~]# tree /srv/salt/prod/modules/ /srv/salt/prod/modules/ ├── haproxy │ ├── files │ │ └── haproxy.cfg │ ├── install.sls │ └── service.sls ├── keepalived │ ├── files │ │ └── keepalived.conf │ ├── install.sls │ └── service.sls ├── lnmp │ ├── files │ │ ├── index.php │ │ └── www.conf │ └── www.sls ├── mysql │ ├── files │ │ └── my.cnf │ ├── install.sls │ └── service.sls ├── nginx │ ├── files │ │ ├── nginx-1.12.2.tar.gz │ │ ├── nginx-1.16.0.tar.gz │ │ ├── nginx.conf.template │ │ └── nginx.service.template │ ├── install.sls │ └── service.sls ├── php │ ├── files │ │ ├── php-5.6.40.tar.gz │ │ ├── php-fpm.conf.template │ │ ├── php-fpm.service.template │ │ ├── php-fpm.template │ │ └── php.ini.template │ ├── install.sls │ └── service.sls ├── pkg.sls └── user └── www.sls 13 directories, 27 files
2）若是須要在某臺服務器上面單獨部署某一部分，參考如下寫法：
[root@salt-master ~]# cat /srv/salt/base/top.sls #部署lnmp及haproxy+keepalived prod: "salt-minion0[3-4]": - modules.lnmp.www "salt-minion0[1-2]": - modules.haproxy.service - modules.keepalived.service #單實例操做說明： prod: "salt-minion04": - modules.nginx.service #單獨安裝nginx時 - modules.mysql.service #單獨安裝mysql時 - modules.php.service #單獨安裝php時 - modules.keepalived.service #單獨安裝keepalived時 - modules.haproxy.service #單獨安裝haproxy時 "salt-minion03": - modules.lnmp.www #單獨部署lnmp環境時
