监控的目的

基础的不用说了，负载，cpu，内存，磁盘

再高级点，各个服务，比如nginx, mysql, php

再深层次，那就是针对你们业务的指标，比如访问日志错误数（5xx）,mysql慢查询，tcp连接数等。

1、准备lnmp环境

#create nginx+php huanjing

yum -y install gcc gcc-c++ ncurses-devel perl openssl openssl-devel pcre pcre-devel zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libmcrypt-devel mhash mcrypt

###rz mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz 到/server/tools/  准备进行编译安装

cd /server/tools

tar -xf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz

\mv mysql-5.5.56-linux-glibc2.5-x86_64 /application/mysql-5.5.56

#mysql -uroot -poldboy123 -e "flush privileges;"

###改进方案：快速上线lnmp环境，使用自己打包的nginx和环境包

2、编译安装zabbix

（zabbix-3.0.9）

yum -y install fping net-snmp-devel unixODBC-devel openssl-devel OpenIPMI-devel java-1.7.0-openjdk-devel.x86_64

cd /server/tools/

###rz zabbix-3.0.9.tar.gz到当前目录

tar xf zabbix-3.0.9.tar.gz

cd zabbix-3.0.9

./configure --prefix=/application/zabbix-3.0.9 --enable-server --enable-agent --enable-java --enable-ipv6 --with-mysql=/application/mysql/bin/mysql_config --with-net-snmp --with-libcurl --with-libxml2 --with-openipmi --with-unixodbc --with-openss

make install

ln -s /application/zabbix-3.0.9/ /application/zabbix

3、添加zabbix用户

useradd zabbix -s /sbin/nologin

4、mysql数据库操作

mysql

create database zabbix character set utf8 collate utf8_bin;

grant all on zabbix.* to zabbix@‘127.0.0.1‘ identified by ‘zabbix‘;

flush privileges;

mysql -uroot zabbix </server/tools/zabbix-3.0.9/database/mysql/schema.sql

mysql -uroot zabbix </server/tools/zabbix-3.0.9/database/mysql/images.sql

mysql -uroot zabbix </server/tools/zabbix-3.0.9/database/mysql/data.sql

5、web代码

mkdir /application/nginx/html/zabbix

cp -a /server/tools/zabbix-3.0.9/frontends/php/* /application/nginx/html/zabbix/

chown -R www.www /application/nginx/html/zabbix/

6、配置zabbix

#youhua php

sed -i ‘s#post_max_size = 8M#post_max_size = 16M#g;s#max_execution_time = 30#max_execution_time = 300#g;s#max_input_time = 60#max_input_time = 600#g;910a date.timezone = Asia/Shanghai‘ /application/php/lib/php.ini

pkill php-fpm

/application/php/sbin/php-fpm

#youhua nginx

cat >/application/nginx/conf/nginx.conf<<EOF

worker_processes 1;

events {

  worker_connections 1024;

}

http {

  include mime.types;

  default_type application/octet-stream;

  sendfile on;

  keepalive_timeout 65;

  server {

  listen 80;

  server_name localhost;

  root html;

  location / {

  root html;

  index index.php index.html index.htm;

  }

  location ~ .*\.(php|php5)?\$ {

  fastcgi_pass 127.0.0.1:9000;

  fastcgi_index index.php;

  include fastcgi.conf;

  }

  access_log logs/zabbix.log;

  }

}

EOF

/application/nginx/sbin/nginx -t

/application/nginx/sbin/nginx -s reload

#youhua zabbix fuwu

sed -i -e ‘77a DBHost=127.0.0.1‘ -e ‘111a DBPassword=zabbix‘ /application/zabbix/etc/zabbix_server.conf

cp /server/tools/zabbix-3.0.9/misc/init.d/fedora/core/zabbix_{server,agentd} /etc/init.d/

sed -i ‘s#BASEDIR=/usr/local#BASEDIR=/application/zabbix#g‘ /et c/init.d/zabbix_{server,agentd}

/etc/init.d/zabbix_server start

###这两步可以放到前面编译安装php的时候一起添加好模块

cd /server/tools/php-5.5.32/ext/gettext

/application/php/bin/phpize #需要扩容php模块的时候需要执行此句

./configure --with-php-config=/application/php/bin/php-config

make && make install

echo " extension = gettext.so">> /application/php/lib/php.ini

/application/php/bin/php -m|grep gettext #检测是否安装成功

cd /server/tools/php-5.5.32/ext/mysqli

/application/php/bin/phpize #需要扩容php模块的时候需要执行此句

./configure --with-php-config=/application/php/bin/php-config

make && make install

echo " extension = mysqli.so">> /application/php/lib/php.ini

/application/php/bin/php -m|grep mysqli

pkill php

lsof -i :9000

/application/php/sbin/php-fpm

lsof -i :9000

#youhua fonts（ziti）

yum -y install wqy-microhei-fonts

\cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /application/nginx/html/zabbix/fonts/DejaVuSans.ttf

###以上全部是服务器的操作！

7、zabbix客户端安装使用

#/etc/init.d/zabbix_agentd start      #服务端的agent（客户端）启动

#新机器的安装方法  仅安装agent监测端即可！

###rz相关软件包到当前目录

yum localinstall -y zabbix-agent-3.0.9-1.el6.x86_64.rpm

sed -i ‘s#Server=127.0.0.1#Server=172.16.1.63#g‘ /etc/zabbix/zabbix_agentd.conf

/etc/init.d/zabbix-agent start

8、邮件告警

ix-agent star

echo "set from=15361848205@189.cn smtp=smtp.189.cn smtp-auth-user=15361848205 smtp-auth-password=123456abc smtp-auth=login " >>/etc/mail.rc

cat >/server/scripts/sendmailtest.sh<<EOF

char="send from 20has-pc by 20has "

mail -s "my dear,\$char \$(date +%F_%T)" 15361848205@189.cn </etc/passwd

EOF

sh /server/scripts/sendmailtest.sh         #模拟邮件测试而已

#mail -s "my dear,2017年7月9日 00:20:26" 714582797@qq.com  </etc/passwd       

#mail -s 邮件主题 收件人 邮件正文

总结

处理了两次天坑：

1、张导的视频在编译安装zabbix的时候是直接yum install java-devel ，在我的机器这样提示找不到安装包，经过和鸡血哥聊天指导 直接yum指定java包解决 

解决办法：yum -y install java-1.7.0-openjdk-devel.x86_64

2、第一次安装zabbix报错是因为张导的视频设置的nginx用户，我的nginx包设置的是www的用户，所以无权限写入

解决方法：chown -R www.www /application/nginx/html/zabbix/
