篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了zabbix 4.0 安装配置(五）相关的知识，希望对你有一定的参考价值。
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
[root@web02 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：
[root@web02 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；
[root@web02 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
[root@web02 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

（5）将userparameter_zapache.conf配置文件上传至/etc/zabbix/zabbix_agentd.d目录，并重启Zabbix Agent：
[root@web02 zabbix_agentd.d]# vim userparameter_zapache.conf UserParameter=zapache[*],/scripts/zapache $1
# systemctl restart zabbix-agent
（6）web01节点使用zabbix-get进行取值测试：
# zabbix_get -s 192.168.11.207 -k zapache[ping]
[root@web01 ~]# zabbix_get -s 192.168.11.207 -k zapache[ping] 0
（7）新建监控项目后，自定义模块，加入到监控主机
3、通过JMX监控Tomcat：
（1）web02节点安装JDK和Tomcat
（2）配置Tomcat支持JMX：
# vim /usr/local/tomcat/bin/catalina.sh，在首行#!/bin/sh下方新增如下代码：
CATALINA_OPTS="$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

# 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 $NF}‘ 15 } 16 listen_queue_len(){ 17 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^listen queu e len:/ {print $NF}‘ 18 } 19 idle_processes(){ 20 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^idle proces ses:/ {print $NF}‘ 21 } 22 active_processes(){ 23 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^active proc esses:/ {print $NF}‘ 24 } 25 total_processes(){ 26 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^total proce sses:/ {print $NF}‘ 27 } 28 max_active_processes(){ 29 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^max active processes:/ {print $NF}‘ 30 } 31 max_children_reached(){ 32 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^max childre n reached:/ {print $NF}‘ 33 } 34 slow_requests(){ 35 /usr/bin/curl -s "http://localhost:"$PHPFPM_PORT"/php-fpm_status" |awk ‘/^slow reques ts:/ {print $NF}‘ 36 } 37 38 case $PHPFPM_COMMAND in 39 start_since) 40 start_since; 41 ;; 42 accepted_conn) 43 accepted_conn; 44 ;; 45 listen_queue) 46 listen_queue; 47 ;; 48 max_listen_queue) 49 max_listen_queue; 50 ;; 51 listen_queue_len) 52 listen_queue_len; 53 ;; 54 idle_processes) 55 idle_processes; 56 ;; 57 active_processes) 58 active_processes; 59 ;; 60 total_processes) 61 total_processes; 62 ;; 63 max_active_processes) 64 max_active_processes; 65 ;; 66 max_children_reached) 67 max_children_reached; 68 ;; 69 slow_requests) 70 slow_requests; 71 ;; 72 *) 73 echo $"USAGE:$0 {start_since|accepted_conn|listen_queue|max_listen_queue|list en_queue_len|idle_processes|active_processes|total_processes|max_active_processes|max_chi ldren_reached}" 74 esac
# 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：
[root@web02 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：
[root@web01 ~]# zabbix_get -s 192.168.11.207 -k php-fpm_status[accepted_conn]
[root@web01 ~]# zabbix_get -s 192.168.11.207 -k php-fpm_status[active_processes]

（4）将redis_status.conf配置文件上传至/etc/zabbix/zabbix_agentd.d目录，并重启Zabbix Agent：
[root@web02 zabbix_agentd.d]# vim redis_status.conf UserParameter=redis_status[*],/scripts/redis_monitor.sh $1 $2
# systemctl restart zabbix-agent
（5）zabbix-server节点使用zabbix-get进行取值测试：
# zabbix_get -s 192.168.11.207 -k redis
