zabbix 4.0 安装配置(五）

一、监控Nginx、httpd、Tomcat、php-fpm、Redis

1、监控Nginx：

（1）web02节点安装Nginx

（2）开启Nginx状态页面：

# cd /etc/nginx

# cp nginx.conf{,.bak}

# vim nginx.conf，在server配置段中新增如下代码：

location = /nginx_status {

stub_status;

}

# nginx -t

# systemctl start nginx

# systemctl status nginx

（3）浏览器访问状态页面：http://192.168.11.207/nginx_status

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

说明：页面状态信息

Active connections：当前活动的客户端连接数，包括Waiting连接数

accepts：接收的客户端连接总数

handled：已处理的连接总数，通常该值与accepts的值相同，除非达到某些资源限制，如worker_connections

requests：客户端请求总数

Reading：Nginx正在读取请求头的当前连接数

Writing：Nginx正在将响应写回到客户端的当前连接数

Waiting：当前等待请求的空闲客户端连接数

（4）将nginx_monitor.sh脚本文件上传至/scripts目录，并赋予执行权限：# chmod +x /scripts/nginx_monitor.sh

[[email protected] scripts]# vim nginx_monitor.sh 

#!/bin/bash
#Script to fetch nginx statuses for monitoring systems
#!/bin/bash
#Script to fetch nginx statuses for monitoring systems

HOST="127.0.0.1"
PORT="80"

function ping {
/sbin/pidof nginx | wc -l
}
function active {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep ‘Active‘ | awk ‘{print $NF}‘
}
function reading {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep ‘Reading‘ | awk ‘{print $2}‘
}
function writing {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep ‘Writing‘ | awk ‘{print $4}‘
}
function waiting {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| grep ‘Waiting‘ | awk ‘{print $6}‘
}
function accepts {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk ‘{print $1}‘
}
function handled {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk ‘{print $2}‘
}
function requests {
/usr/bin/curl "http://$HOST:$PORT/nginx_status" 2>/dev/null| awk NR==3 | awk ‘{print $3}‘
}
$1

（5）将nginx_status.conf配置文件上传至/etc/zabbix/zabbix_agentd.d目录，并重启Zabbix Agent：

[[email protected] zabbix_agentd.d]# vim nginx_status.conf 

UserParameter=nginx_status[*],/scripts/nginx_monitor.sh $1

# systemctl restart zabbix-agent

（6）web01节点使用zabbix-get进行取值测试：

# zabbix_get -s 192.168.11.207 -k nginx_status[active]

# zabbix_get -s 192.168.11.207 -k nginx_status[accepts]

# zabbix_get -s 192.168.11.207 -k nginx_status[requests]

（7）新建监控项目后，自定义模块，加入到监控主机

2、监控httpd：

（1）web02节点安装httpd，修改httpd-server-status.conf的内容；

[[email protected] conf.d]# vim httpd-server-status.conf 

#
# This is a sample Apache config file to setup status page.
# Put it in /etc/httpd/conf.d/ or otherwise integrate with Apache conf.
#

#
# ExtendedStatus controls whether Apache will generate "full" status
# information (ExtendedStatus On) or just basic information (ExtendedStatus
# Off) when the "server-status" handler is called. The default is Off.
#
ExtendedStatus On

#
# Allow server status reports generated by mod_status,
# with the URL of http://servername/server-status
# Change the ".example.com" to match your domain to enable.
#
<Location /server-status>
    SetHandler server-status
    Require all granted
#    Order deny,allow
#    Deny from all
#    Allow from localhost
</Location>
ExtendedStatus On

（2）将httpd-server-status.conf配置文件上传至/etc/httpd/conf.d目录，开启httpd状态页面

[[email protected] zabbix_agentd.d]# vim userparameter_zapache.conf
UserParameter=zapache[*],/scripts/zapache $1

# httpd -t

# systemctl start httpd

# systemctl status httpd

（3）浏览器访问状态页面：http://192.168.11.207/server-status

（4）将zapache脚本文件上传至/scripts目录，并赋予执行权限：# chmod +x /scripts/zapache

（5）将userparameter_zapache.conf配置文件上传至/etc/zabbix/zabbix_agentd.d目录，并重启Zabbix Agent：

[[email protected] zabbix_agentd.d]# vim userparameter_zapache.conf 

UserParameter=zapache[*],/scripts/zapache $1

# systemctl restart zabbix-agent

（6）web01节点使用zabbix-get进行取值测试：

# zabbix_get -s 192.168.11.207 -k zapache[ping]

[[email protected] ~]# zabbix_get -s 192.168.11.207 -k zapache[ping]
0

（7）新建监控项目后，自定义模块，加入到监控主机

3、通过JMX监控Tomcat：

（1）web02节点安装JDK和Tomcat

（2）配置Tomcat支持JMX：

# vim /usr/local/tomcat/bin/catalina.sh，在首行#!/bin/sh下方新增如下代码：

CATALINA_OPTS="$CATALINA_OPTS -Djava.rmi.server.hostname=192.168.11.207 -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

说明：

-Dcom.sun.management.jmxremote：启用远程监控JVM

-Djava.rmi.server.hostname=192.168.11.207：Tomcat的IP地址，而非Zabbix Server的IP地址

-Dcom.sun.management.jmxremote.port=12345：默认启动的JMX端口号

-Dcom.sun.management.jmxremote.ssl=false：不使用SSL认证

-Dcom.sun.management.jmxremote.authenticate=false：不使用用户名密码认证

CATALINA_OPTS和JAVA_OPTS的区别：

CATALINA_OPTS：只被Tomcat使用

JAVA_OPTS：被所有Java应用程序使用

# /usr/local/tomcat/bin/catalina.sh configtest

# /usr/local/tomcat/bin/startup.sh

# ss -tunlp | grep -w :12345

（3）web02节点安装Zabbix Java Gateway：# yum -y install zabbix-java-gateway

（4）web02节点修改zabbix_java_gateway.conf配置文件：

# cd /etc/zabbix

# cp zabbix_java_gateway.conf{,.bak}

# vim zabbix_java_gateway.conf


修改前
修改后

#   LISTEN_IP="0.0.0.0"
LISTEN_IP="192.168.0.122"

# LISTEN_PORT=10052
LISTEN_PORT=10052

#   START_POLLERS=5
START_POLLERS=5

#   TIMEOUT=3
TIMEOUT=10

（5）web02节点启动Zabbix Java Gateway：

# systemctl start zabbix-java-gateway

# systemctl status zabbix-java-gateway

# ss -tunlp | grep -w :10052

# systemctl enable zabbix-java-gateway

（6）web01节点修改zabbix_server.conf配置文件：

# vim /etc/zabbix/zabbix_server.conf


修改前
修改后

#   JavaGateway=
JavaGateway=192.168.0.122

#   JavaGatewayPort=10052
JavaGatewayPort=10052

#   StartJavaPollers=0
StartJavaPollers=5

# systemctl restart zabbix-server

备注：StartJavaPollers的值要小于等于START_POLLERS的值

（7）Zabbix Web添加web02节点的JMX监控接口：

说明：IP为Zabbix Java Gateway所部署服务器的IP，端口为Tomcat中配置的JMX远程端口

（8）web02节点链接Tomcat监控模板：

（9）查看最新监控数据：

4、监控php-fpm：

（1）web02节点安装php-fpm

（2）修改www.conf配置文件：

# cd /etc/php-fpm.d

# cp www.conf{,.bak}

# vim www.conf


修改前
修改后

user   = apache
user   = nginx

group   = apache
group   = nginx

;pm.status_path   = /status
pm.status_path   = /php-fpm_status

（3）开启php-fpm状态页面：

# vim /etc/nginx/nginx.conf 在server配置段中新增如下代码：
location / {

root   html;

index  index.php index.html index.htm;

}

location = /php-fpm_status {

fastcgi_pass    127.0.0.1:9000;

fastcgi_index   index.php;

fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

include        fastcgi_params;

}

# nginx -t
# systemctl restart nginx php-fpm
# ss -tunlp | grep -w :80
# ss -tunlp | grep -w 9000

（4）浏览器访问状态页面：http://192.168.11.207/php-fpm_status

（5）将php-fpm_monitor.sh脚本文件上传至/scripts目录，并赋予执行权限：

  1 #!/bin/bash
  2 PHPFPM_COMMAND=$1
  3 PHPFPM_PORT=80
  4 start_since(){
  5     /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^start since    :/ {print $NF}‘
  6 }
  7 accepted_conn(){
  8     /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^accepted co    nn:/ {print $NF}‘
  9 }
 10 listen_queue(){
 11     /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^listen queu    e:/ {print $NF}‘
 12 }
 13 max_listen_queue(){
 14     /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^max listen     queue:/ {print $NF}‘

# chmod +x /scripts/php-fpm_monitor.sh

（6）将php-fpm_status.conf配置文件上传至/etc/zabbix/zabbix_agentd.d目录，并重启Zabbix Agent：

[[email protected] zabbix_agentd.d]# vim php-fpm_status.conf 

UserParameter=php-fpm_status[*],/scripts/php-fpm_monitor.sh "$1"

# systemctl restart zabbix-agent

（7）zabbix-server节点使用zabbix-get进行取值测试：

[[email protected] ~]# zabbix_get -s 192.168.11.207 -k php-fpm_status[accepted_conn]

[[email protected] ~]# zabbix_get -s 192.168.11.207 -k php-fpm_status[active_processes]

（8）新建监控项目后，自定义模块，加入到监控主机

（9）查看最新监控数据：

5、监控Redis：

（1）web02节点安装Redis

（2）查看Redis状态信息：
