zabbix源码安装

安装mariadb(mysql)

// 执行安装命令
# yum -y install mariadb mariadb-server mariadb-devel

// 启动服务
# systemctl start mariadb

// 设置为开机启动
# systemctl enable mariadb

// 修改root登录密码
# mysql_secure_installation
Enter current password for root (enter for none): [回车]
Set root password? [Y/n] y
New password: 
Re-enter new password: 
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] n
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

// 测试登陆
# mysql -uroot -ppassword

// 设置root访问权限
# mysql -uroot -ppassword
MariaDB [(none)]> grant all privileges on *.* to 'root'@'%' identified by 'qwe123' with grant option;
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit;

安装依赖库

// 以下二选一
// 最小
# yum -y install gcc net-snmp-devel libxml2-devel libcurl-devel  libevent libevent-devel
// 完全
# yum -y install gcc net-snmp-devel net-snmp net-snmp-utils libxml2 libxml2-devel libcurl libcurl-devel libevent libevent-devel

下载源码，并配置安装
下载地址：
https://www.zabbix.com/download
https://downloads.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.4.4/zabbix-3.4.4.tar.gz
上传zabbix-3.4.4.tar.gz到/home目录下

# cd /home
# tar -zxf zabbix-3.4.4.tar.gz
# cd zabbix-3.4.4
# ./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --enable-java --with-mysql --enable-ipv6 --with-net-snmp --with-libcurl --with-libxml2
# make && make install

初始化数据

# mysql -uroot -ppassword
MariaDB [none]> create database if not exists zabbix default character set utf8 collate utf8_general_ci;
MariaDB [none]> use zabbix;
MariaDB [zabbix]> source /home/zabbix-3.4.4/database/mysql/schema.sql;
MariaDB [zabbix]> source /home/zabbix-3.4.4/database/mysql/images.sql;
MariaDB [zabbix]> source /home/zabbix-3.4.4/database/mysql/data.sql;

安装fping
zabbix 3之后把ping更换为fping了，所以需要安装fping

# wget http://www.fping.org/dist/fping-4.0.tar.gz
# tar -zxvf fping-4.0.tar.gz
# cd fping-4.0
# ./configure --prefix=/usr/local/fping
# make && make install

配置

// server配置
# cd /usr/local/zabbix/
# vi ./etc/zabbix_server.conf
DBHost=localhost
DBName=zabbix
DBUser=root
DBPassword=password
AllowRoot=1
FpingLocation=/usr/local/fping/sbin/fping

// agent配置
# vi ./etc/zabbix_agentd.conf
Server=0.0.0.0/0
Hostname=Zabbix server #注释掉
AllowRoot=1

启动服务

# /usr/local/zabbix/sbin/zabbix_server
# /usr/local/zabbix/sbin/zabbix_agent

配置前端环境

// 安装apache+php
# yum -y install httpd httpd-devel php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml php-bcmath

// 复制前端代码到站点下
# cp -r /home/zabbix-3.4.4/frontends/php /var/www/html/zabbix

// 关闭防火墙
# systemctl stop firewalld
# setenforce 0
# vi /etc/selinux/config
SELINUX=disabled

// 修改php配置
# vi /etc/php.ini
memory_limit=128M
post_max_size=16M
upload_max_filesize=20M
max_execution_time=300
max_input_time=300
date.timezone=Asia/Shanghai

// 重启站点
# systemctl restart httpd

访问站点按提示进行配置即可
http://localhost/zabbix

zabbix配置Java Gateway

查看是否已经安装了zabbix_java
/usr/local/zabbix/sbin/zabbix_java/start.sh 是否存在
如未安装，则进入zabbix的源码目录，进行zabbix_java的安装

# cd /home/zabbix-3.4.4
# ./configure --prefix=/usr/local/zabbix --enable-java
# make && make install

修改zabbix_server的配置文件

# vi /usr/local/zabbix/etc/zabbix_server.conf
JavaGateway=localhost
JavaGatewayPort=10052
StartJavaPollers=5

然后重启zabbix_server

启动zabbix_java

# /usr/local/zabbix/sbin/zabbix_java/startup.sh

zabbix配置mysql监控

编辑脚本文件/usr/local/zabbix/etc/zabbix_agentd.conf.d/chk_mysql.sh

# vi /usr/local/zabbix/etc/zabbix_agentd.conf.d/chk_mysql.sh

#!/bin/bash

# 用户名
MYSQL_USER='root'

# 密码
MYSQL_PWD='asd123'

# 主机地址/IP

# 端口
MYSQL_PORT='3306'

# 数据连接
MYSQL_CONN="/usr/bin/mysqladmin -u${MYSQL_USER} -p${MYSQL_PWD} -h${MYSQL_HOST} -P${MYSQL_PORT}"

# 参数是否正确
if [ $# -ne "1" ];then
    echo "arg error!"
fi

# 获取数据
case $1 in

        result=`${MYSQL_CONN} extended-status |grep -w "$1" |cut -d"|" -f3`
                echo $result
                ;;
esac

编辑配置文件/usr/local/zabbix/etc/zabbix_agentd.conf.d/zabbix_mysql.conf

# vi /usr/local/zabbix/etc/zabbix_agentd.conf.d/zabbix_mysql.conf

#Mysql版本
UserParameter=mysql.version,mysql -V
# 获取mysql性能指标,这个是上面定义好的脚本
UserParameter=mysql.status[*],/usr/local/zabbix/etc/zabbix_agentd.conf.d/chk_mysql.sh $1
# 获取mysql运行状态
UserParameter=mysql.ping,mysqladmin -uroot -pqwe123 -P3306 -hlocalhost  ping | grep -c alive

编辑zabbix_agentd的配置文件，加入zabbix_mysql.conf配置

# vi /usr/local/zabbix/etc/zabbix_agentd.conf

// 去掉#
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf

重启zabbix_agent
测试是否成功

# /usr/local/zabbix/bin/zabbix_get -s 127.0.0.1 -p 10050 -I 172.16.1.162 -k mysql.version

附录: windows下的脚本

mysql_ping.vbs

Set objFS =CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
str1 = getCommandOutput("mysqladmin -uroot -pqwe123 ping")
  
If Instr(str1,"alive") > 0Then
WScript.Echo 1
Else
WScript.Echo 0
End If
  
Function getCommandOutput(theCommand)
  
Dim objShell, objCmdExec
Set objShell =CreateObject("WScript.Shell")
Set objCmdExec = objshell.exec(thecommand)
getCommandOutput =objCmdExec.StdOut.ReadAll
end Function

mysql_status.vbs

Set objFS = CreateObject("Scripting.FileSystemObject")
Set objArgs = WScript.Arguments
str1 = getCommandOutput("mysqladmin -uroot -pqwe123 extended-status")
Arg = objArgs(0)
str2 = Split(str1,"|")
  
For i = LBound(str2) to UBound(str2)
  
If Trim(str2(i)) = Arg Then   
WScript.Echo TRIM(str2(i+1))
Exit For
End If
next
  
  
Function getCommandOutput(theCommand)
  
Dim objShell, objCmdExec
Set objShell =CreateObject("WScript.Shell")
Set objCmdExec = objshell.exec(thecommand)
getCommandOutput =objCmdExec.StdOut.ReadAll
  
end Function

zabbix配置tomcat监控

启用tomcat的jmx

windows下，在catalina.bat 头部增加

set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false

linux下，在catalina.sh中，CATALINA_OUT前增加

CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=8888 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Djava.rmi.server.hostname=192.168.2.207"

下载catalina-jmx-remote.jar到tomcat/lib下
修改tomcat的server.xml文件，加入以下代码

<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="12345" rmiServerPortPlatform="12345" />

启动tomcat
确认zabbix_server启用了Java Gateway，参考上面
在zabbix的控制台添加主机JMX接口
172.16.1.162:12345

linux snmp配置

确认snmp代理是否已安装

# rpm -q net-snmp

如果未安装，安装snmp

# yum install net-snmp net-snmp-devel net-snmp-utils

修改配置 /etc/snmp/snmpd.conf

com2sec notConfigUser  default       public

#view mib2   included  .iso.org.dod.internet.mgmt.mib-2 fc
view mib2   included  .iso.org.dod.internet.mgmt.mib-2 fc

#access  notConfigGroup ""      any       noauth    exact  systemview none none
access  notConfigGroup ""      any       noauth    exact  mib2 none none

启动并设置为自启动

systemctl start snmpd
systemctl enable snmpd

zabbix自动发现各网卡MAC地址

在zabbix控制台，找到模版Template Module Interfaces SNMPv2

zabbix配置ngnix监控

启用nginx status

// 下载nginx源码，再用以下命令编译安装
# ./configure --with-http_stub_status_module
# make && make install

// 修改/usr/local/nginx/conf/nginx.conf，增加以下location
location /ngx_status {
    stub_status on;
    access_log off;
}

启动且访问nginx。
http://127.0.0.1/ngx_status

Active connections: 3 
server accepts handled requests
 3 3 1 
Reading: 0 Writing: 1 Waiting: 2

编写服务端获取nginx信息的脚本文件ngx_status.sh

#!/bin/bash

HOST="192.168.2.207"
PORT="81"

# 检测nginx进程是否存在
function ping {
    /sbin/pidof nginx | wc -l 
}
# 检测nginx性能
function active {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
    /usr/bin/curl "http://$HOST:$PORT/ngx_status/" 2>/dev/null| awk NR==3 | awk '{print $3}'
}
# 执行function
$1

测试使用

zabbix_get -s localhost -k 'nginx.status[ping]'
