在/root目錄下建立nagios文件夾
mkdir ~/nagios
進入/root/nagios文件夾
cd ~/nagios
下載nagios程序及nagios增長插件
wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.8.tar.gz
wget http://www.nagios-plugins.org/download/nagios-plugins-2.0.3.tar.gz
解壓nagios增長插件程序包及增長插件

tar zxvf nagios-plugins-2.0.3.tar.gz
進入/root/nagios/nagios-4.0.8文件夾
cd nagios-4.0.8
編譯安裝nagios-4.0.8
./configure --with-command-group=nagcmd
make all
make install
make install-init
make install-commandmode
make install-config
編輯nagios的contacts.cfg文件(存放設置接收報警的用戶的,此布最後修改)
vim /usr/local/nagios/etc/objects/contacts.cfg
################################ 華麗分割線O(∩_∩)O~ ########################
define contact{

email 15000000000@139.com ;這裏設置郵箱
pager 15000000000 ;這裏是我後來添加的字段,若是要在commands.cfg配置文件中獲取這個字段信息就使用 $CONTACTPAGER$ 表示(既是contact中的pager字段)。

設置nagios登陸用戶nagiosadmin的密碼
htpasswd -s -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
注:關於nagios監控-多用戶管理,如下文章不錯
http://blog.csdn.net/liqfyiyi/article/details/8778671
進入/root/nagios/nagios-plugins-2.0.3文件夾
cd ~/nagios/nagios-plugins-2.0.3
安裝nagios增長插件
make
make install
使用下面的命令覈對nagios配置文件是否有錯誤,最好每次修改nagios配置文件都測試下。
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
chkconfig --add nagios
chkconfig --level 35 nagios on
systemctl start nagios.service
注:關於nagios在Centos7.0上的安裝方法我參照的是下面這個連接的文章(洋文的)
http://www.tuicool.com/articles/vYFv2i7
啓用http服務
systemctl start httpd.service
設置httpd開機啓動
chkconfig httpd on
systemctl enable httpd
修改Centos 7的防火牆,使其http服務可被訪問。
查看防火牆所在網絡區域,默認爲public
firewall-cmd --get-default-zone
查看public所容許訪問的服務
firewall-cmd --zone=public --list-services
添加運行訪問http服務
firewall-cmd --permanent --zone=public --add-service=http
刪除不須要的服務(可選)
firewall-cmd --permanent --zone=public --remove-service=dhcpv6-client
從新加載防火牆
firewall-cmd --reload
查看public所容許訪問的服務,驗證是否修改爲功
firewall-cmd --zone=public --list-services
配置sendEmail發送nagios郵件報警
到官網下載sendEmail安裝包
http://caspian.dotconf.net/menu/Software/SendEmail/
解壓sendEmail程序包(這裏下載後放在我統一/root目錄下)
cd /root
tar zxvf sendEmail-v1.56.tar.gz
進入解壓出來後的目錄
cd sendEmail-v1.56
複製sendEmail程序至/usr/local/bin
cp sendEmail /usr/local/bin
查看/usr/local/bin/sendEmail的權限,是否普通用戶可讀可執行
ll /usr/local/bin/sendEmail
這裏可嘗試用sendEmail發送郵件
/usr/local/bin/sendEmail -f fasongzhe@126.com -t jieshouzhe@qq.com -s smtp.126.com -u "這裏設置主題" -xu fasongzhe -xp fasongzhedemima
解釋:
-f 表示發送者的郵箱
-t 表示接收者的郵箱
-s 表示SMTP服務器的域名或者ip
-u 表示郵件的主題
-xu 表示SMTP驗證的用戶名
-xp 表示SMTP驗證的密碼(注意,這個密碼貌似有限制,例如我用d!5neyland就不能被正確識別)
-m 表示郵件的內容
若是你不帶-m參數的話,就會提示你自行輸入
Reading message body from STDIN because the ‘-m’ option was not used.
If you are manually typing in a message:
- First line must be received within 60 seconds.
- End manual input with a CTRL-D on its own line
輸入完成後使用CTRL-D來結束
既然nagios要使用sendEmail來發警告郵件,那麼就要修改commands.cfg中關於發郵件的命令的定義,咱們如今來修改notify-by-email這個命令,以下
################################ 華麗分割線O(∩_∩)O~ ####################
# 'notify-host-by-email' command definition
define command{

注:關於郵件報警配置我參考的是如下這個連接的文章
http://xiaosa.blog.51cto.com/665033/381310/
微信報警配置
首先註冊個微信公共平臺帳號
一、基本信息---->二、郵箱激活
https://mp.weixin.qq.com/cgi-bin/readtemplate?t=register/step1_tmpl&lang=zh_CN
---->三、選擇類型
選擇「企業號」
---->四、信息登記---->五、公衆號信息
(注:「我選的是「其餘組織」,能夠在百度查下本身公司的「組織機構代碼」)
登陸微信公共平臺進行配置
打開通信錄添加成員
打開應用中心添加應用
查看並記住發送報警使用的應用的ID
點擊設置號本身的帳號信息,點擊「權限管理」右邊的「管理」按鍵進入權限管理頁面,新建管理組(名字本身定)
根據添加管理員(內部)
根據實際狀況修改「通信錄權限」、「應用權限」、「敏感接口權限」的配置。
在該頁面最下方有個開發者憑據,這個是客戶端與服務器創建鏈接須要用到的。
簡單的使用nagios發微信報警主要用到微信API如下兩個格動做:
一、創建鏈接:獲取AccessToken;
二、發送消息。
可在微信企業號接口調試工具的頁面測試下。
一、發送請求地址,獲取AccessToken
二、發送請求地址,發送消息
其中的body部分能夠這樣定義:
{
"touser": "這裏設置公衆平臺通信錄中的用戶名,可用@all表明全部用戶",
"msgtype": "text",
"agentid": "0",
"text": {
"content": "發送的內容,稍後會用python發送請求地址,暫不能發送中文"
},
"safe":"0"
}
詳細接口信息可參考微信官方接口文檔介紹
http://qydev.weixin.qq.com/wiki/index.php?title=%E9%A6%96%E9%A1%B5
安裝Python-3.4
科普下:
有些人在linux下使用python發送微信鏈接時會報urllib2.URLError: <urlopen error unknown url type: https>這個錯誤,是由於python沒有SSL模塊,需從新編譯安裝python。步驟以下
安裝openssl與openssl-devel包
yum install openssl
yum install openssl-devel
到官網下載Python3的最新版
https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz
解壓Python安裝包(我默認放在/root下)
cd /root
tar xzvf Python-3.4.3.tgz
進入python源代碼文件夾,進入Modules文件夾,修改Setup.dist,使其支持發送https請求。
cd /root/Python-3.4.3/Modules
vim Setup.dist
將
# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
#SSL=/usr/local/ssl
#_ssl _ssl.c \
# -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
# -L$(SSL)/lib -lssl -lcrypto
修改成
# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
編譯安裝,設置安裝目錄爲/usr/local/python-3.4,以避免與系統已安裝的python2衝突。
./configure --prefix=/usr/local/python-3.4
make
make install
#############################這部分有興趣能夠弄,可忽略###################
爲方便後續測試可在PATH中添加python-3.4的運行路徑,之後在終端可直接輸入命令python3.4執行文件。
vim /etc/profile
在文檔最後,添加:
export PATH="/usr/local/python-3.4/bin:$PATH"
保存,退出,而後運行
source /etc/profile
可驗證是否修改無誤。

編輯好python程序後可使用如下命令測試,主機報警示例(將下面命令中文改成英文):
/usr/local/python-3.4/bin/python3.4 /usr/local/nagios/python/notify-host-by-weixin.py "微信通信錄中的用戶名separator時間標題separator主機名separator主機狀態separator主機地址separator主機輸出信息separator時間"
成功後會有 b'{"errcode":0,"errmsg":"ok"}' 的提示。
接下來開始對接nagios報警
而後定義發送微信的命令,修改commands.cfg文件,定義主機報警命令notify-host-by-weixin,及服務報警命令notify-service-by-weixin。
vim /usr/local/nagios/etc/objects/commands.cfg
在文檔最後面添加一下信息便可。

cfg_dir=/usr/local/nagios/etc/campus/south
#添加了一個讀取配置文件的目錄,想放哪本身決定,之後將主機的信息放在/usr/local/nagios/etc/campus/south這個目錄即可讀取。
建立文件夾/usr/local/nagios/etc/campus/south
mkdir /usr/local/nagios/etc/campus
mkdir /usr/local/nagios/etc/campus/south
建立主機配置文件(名字隨便取)
cd /usr/local/nagios/etc/campus/south
