SaltStack项目实战（六）
SaltStack项目实战
- 系统架构图
一、初始化
1、salt环境配置，定义基础环境、生产环境（base、prod）
vim /etc/salt/master
修改file_roots
file_roots:
base:
- /srv/salt/base
prod:
- /srv/salt/prod mkdir -p /srv/salt/base
mkdir -p /srv/salt/prod
pillar配置
vim /etc/salt/master
修改pillar_roots
pillar_roots:
base:
- /srv/pillar/base
pord:
- /srv/pillar/prod mkdir -p /srv/pillar/base
mkdir -p /srv/pillar/prod
服务重启 systemctl restart salt-master
2、salt base环境初始化：
mkdir -p /srv/salt/base/init # 环境初始化目录
mkdir -p /srv/salt/base/init/files # 配置文件目录
1）dns配置
准备dns配置文件，放入/srv/salt/base/init/files目录下
cp /etc/resolv.conf /srv/salt/base/init/files/
vi /srv/salt/base/init/dns.sls
/etc/resolv.conf:
file.managed:
- source: salt://init/files/resolv.conf
- user: root
- gourp: root
- mode: 644
2）histroy记录时间
vi /srv/salt/base/init/history.sls
/etc/profile:
file.append:
- text:
- export HISTTIMEFORMAT="%F %T `whoami` "
3）记录命令操作
vi /srv/salt/base/init/audit.sls
/etc/bashrc:
file.append:
- text:
- export PROMPT_COMMAND='{ msg=$(history 1 | { read x y; echo $y; });logger "[euid=$(whoami)]":$(who am i):[`pwd`]"$msg"; }'
4）内核参数优化
vi /srv/salt/base/init/sysctl.sls
net.ipv4.ip_local_port_range:
sysctl.present:
- value: 10000 65000
fs.file-max:
sysctl.present:
- value: 2000000
net.ipv4.ip_forward:
sysctl.present:
- value: 1
vm.swappiness:
sysctl.present:
- value: 0
5）安装yum仓库
vi /srv/salt/base/init/epel.sls
yum_repo_release:
pkg.installed:
- sources:
- epel-release: http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
- unless: rpm -qa | grep epel-release-latest-7
6）安装zabbix-agent
准备zabbix-agent配置文件，放入/srv/salt/base/init/files目录下
cp /etc/zabbix/zabbix_agentd.conf /srv/salt/base/init/files/
修改 vi /etc/zabbix/zabbix_agentd.conf
vi /srv/salt/base/init/zabbix_agent.sls
zabbix-agent:
pkg.installed:
- name: zabbix-agent
file.managed:
- name: /etc/zabbix/zabbix_agentd.conf
- source: salt://init/files/zabbix_agentd.conf
- template: jinja
- backup: minion
- defaults:
Server: {{ pillar['zabbix-agent']['Zabbix_Server'] }}
Hostname: {{ grains['fqdn'] }}
- require:
- pkg: zabbix-agent
service.running:
- enable: True
- watch:
- pkg: zabbix-agent
- file: zabbix-agent zabbix_agentd.d:
file.directory:
- name: /etc/zabbix/zabbix_agentd.d
- watch_in:
- service: zabbix-agent
- require:
- pkg: zabbix-agent
- file: zabbix-agent
备注：“- backup: minion”表示备份，如果文件改动，会将之前的文件备份到/var/cache/salt/file_backup目录下
7）编写init.sls总文件，引用其它文件
vi /srv/salt/base/init/init.sls
include:
- init.dns
- init.history
- init.audit
- init.sysctl
- init.epel
- init.zabbix_agent
执行命令： salt "*" state.sls init.init

8）创建top文件
vi /srv/salt/base/top.sls
base:
'*':
- init.init
测试 salt "*" state.highstate test=True
执行 salt "*" state.highstate
3、pillar base初始化
1）zabbix agent配置，指定zabbix server地址，用于sls文件引用
mkdir -p /srv/pillar/base/zabbix
vi /srv/pillar/base/zabbix/agent.sls
zabbix-agent:
Zabbix_Server: 192.168.137.11
编写top，引用/srv/pillar/base/zabbix/agent文件
vi /srv/pillar/base/top.sls
base:
'*':
- zabbix.agent
测试 salt '*' pillar.items
二、haproxy
mkdir -p /srv/salt/prod/modules/haproxy
mkdir -p /srv/salt/prod/modules/keepalived
mkdir -p /srv/salt/prod/modules/memcached
mkdir -p /srv/salt/prod/modules/nginx
mkdir -p /srv/salt/prod/modules/php
mkdir -p /srv/salt/prod/modules/pkg
mkdir -p /srv/salt/prod/cluster
mkdir -p /srv/salt/prod/modules/haproxy/files/
mkdir -p /srv/salt/prod/cluster/files
1）系统gcc编译包等
vi /srv/salt/prod/pkg/make.sls
make-pkg:
pkg.installed:
- names:
- gcc
- gcc-c++
- glibc
- make
- autoconf
- openssl
- openssl-devel
- pcre
- pcre-devel
2） 自安装
cd /usr/local/src
tar xvf haproxy-1.6.3.tar.gz
cd haproxy-1.6.3/
make TARGET=linux2628 PREFIX=/usr/local/haproxy-1.6.3
make install PREFIX=/usr/local/haproxy-1.6.3
ln -s /usr/local/haproxy-1.6.3 /usr/local/haproxy
修改启动脚本，放入salt下
vi /usr/local/src/haproxy-1.6.3/examples/haproxy.init
BIN=/usr/local/haproxy/sbin/$BASENAME
cp /usr/local/src/haproxy-1.6.3/examples/haproxy.init /srv/salt/prod/modules/haproxy/files/
haproxy-1.6.3.tar.gz安装包放入/srv/salt/prod/modules/haproxy/files/目录下
3）创建install.sls文件，用于安装haproxy
vi /srv/salt/prod/modules/haproxy/install.sls
include:
- modules.pkg.make haproxy-install:
file.managed:
- name: /usr/local/src/haproxy-1.6.3.tar.gz
- source: salt://modules/haproxy/files/haproxy-1.6.3.tar.gz
- mode: 755
- user: root
- group: root
cmd.run:
- name: cd /usr/local/src && tar zxf haproxy-1.6.3.tar.gz && cd haproxy-1.6.3 && make TARGET=linux2628 PREFIX=/usr/local/haproxy-1.6.3 && make install PREFIX=/usr/local/haproxy-1.6.3 && ln -s /usr/local/haproxy-1.6.3 /usr/local/haproxy
- unless: test -L /usr/local/haproxy
- require:
- pkg: make-pkg
- file: haproxy-install haproxy-init:
file.managed:
- name: /etc/init.d/haproxy
- source: salt://modules/haproxy/files/haproxy.init
- mode: 755
- user: root
- group: root
- require_in:
- file: haproxy-install
cmd.run:
- name: chkconfig --add haproxy
- unless: chkconfig --list| grep haproxy net.ipv4.ip_nonlocal_bind:
sysctl.present:
- value: 1 haproxy-config-dir:
file.directory:
- name: /etc/haproxy
- mode: 755
- user: root
- group: root
备注： “- unless” 如果unless后面的命令返回为True，那么就不执行当前状态命令
4）创建haproxy配置文件
vi /srv/salt/prod/cluster/files/haproxy-outside.cfg
global
maxconn 100000
chroot /usr/local/haproxy
uid 99
gid 99
daemon
nbproc 1
pidfile /usr/local/haproxy/logs/haproxy.pid
log 127.0.0.1 local3 info
defaults
option http-keep-alive
maxconn 100000
mode http
timeout connect 5000ms
timeout client 50000ms
timeout server 50000ms
listen stats
mode http
bind 0.0.0.0:8888
stats enable
stats uri /haproxy-status
stats auth haproxy:saltstack
frontend frontend_www_example_com
bind 192.168.137.21:80
mode http
option httplog
log global
default_backend backend_www_example_com
backend backend_www_example_com
option forwardfor header X-REAL-IP
option httpchk HEAD / HTTP/1.0
balance source server web-node1 192.168.137.11:8080 check inter 2000 rise 30 fall 15
server web-node2 192.168.137.12:8080 check inter 2000 rise 30 fall 15
创建haproxy-outside.sls文件，用于配置haproxy
vi /srv/salt/prod/cluster/haproxy-outside.sls
include:
- modules.haproxy.install haproxy-service:
file.managed:
- name: /etc/haproxy/haproxy.cfg
- source: salt://cluster/files/haproxy-outside.cfg
- user: root
- group: root
- mode: 644
service.running:
- name: haproxy
- enable: True
- reload: True
- require:
- cmd: haproxy-install
- watch:
- file: haproxy-service
5）配置top file
vi /srv/pillar/base/top.sls
base:
'*':
- zabbix.agent
prod:
'linux-node*':
- cluster.haproxy-outside
测试 salt "*" state.highstate test=True
执行 salt "*" state.highstate
结果：
三、keepalived
1）创建files目录，将keepalived-1.2.17.tar.gz安装包、keepalived.sysconfig、keepalived.init放入
mkdir -p /srv/salt/prod/modules/keepalived/files
2）创建install.sls文件
vi /srv/salt/prod/modules/keepalived/install.sls
{% set keepalived_tar = 'keepalived-1.2.17.tar.gz' %}
{% set keepalived_source = 'salt://modules/keepalived/files/keepalived-1.2.17.tar.gz' %} keepalived-install:
file.managed:
- name: /usr/local/src/{{ keepalived_tar }}
- source: {{ keepalived_source }}
- mode: 755
- user: root
- group: root
cmd.run:
- name: cd /usr/local/src && tar zxf {{ keepalived_tar }} && cd keepalived-1.2.17 && ./configure --prefix=/usr/local/keepalived --disable-fwmark && make && make install
- unless: test -d /usr/local/keepalived
- require:
- file: keepalived-install /etc/sysconfig/keepalived:
file.managed:
- source: salt://modules/keepalived/files/keepalived.sysconfig
- mode: 644
- user: root
- group: root /etc/init.d/keepalived:
file.managed:
- source: salt://modules/keepalived/files/keepalived.init
- mode: 755
- user: root
- group: root keepalived-init:
cmd.run:
- name: chkconfig --add keepalived
- unless: chkconfig --list | grep keepalived
- require:
- file: /etc/init.d/keepalived /etc/keepalived:
file.directory:
- user: root
- group: root
执行命令：salt '*' state.sls modules.keepalived.install saltenv=prod
3）创建keepalived配置文件haproxy-outside-keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
saltstack@example.com
}
notification_email_from keepalived@example.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id {{ROUTEID}}
} vrrp_instance haproxy_ha {
state {{STATEID}}
interface eth0
virtual_router_id 36
priority {{PRIORITYID}}
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.137.21
}
}
创建haproxy-outside-keepalived.sls
vi /srv/salt/prod/cluster/haproxy-outside-keepalived.sls
include:
- modules.keepalived.install keepalived-server:
file.managed:
- name: /etc/keepalived/keepalived.conf
- source: salt://cluster/files/haproxy-outside-keepalived.conf
- mode: 644
- user: root
- group: root
- template: jinja
{% if grains['fqdn'] == 'linux-node1.example.com' %}
- ROUTEID: haproxy_ha
- STATEID: MASTER
- PRIORITYID: 150
{% elif grains['fqdn'] == 'linux-node2.example.com' %}
- ROUTEID: haproxy_ha
- STATEID: BACKUP
- PRIORITYID: 100
{% endif %}
service.running:
- name: keepalived
- enable: True
- watch:
- file: keepalived-server
4）将keepalived加入top FILE
vi /srv/salt/base/top.sls
base:
'*':
- init.init
prod:
'linux-node*':
- cluster.haproxy-outside
- cluster.haproxy-outside-keepalived
测试 salt "*" state.highstate test=True
执行 salt "*" state.highstate
