軟件環境部署
一、部署docker-ce版本以及pip工具，並安裝docker-compose工具
#yum install -y docker-ce python36-setuptools python36-pip #pip3 install docker-compose==1.23.2
二、編寫docker-compose的yaml文件
version: '3.7' services: zabbix-server: image: docker-registry.hexun.com/system_ops/zabbix-server-mysql:centos-4.0-latest ports: - "10051:10051" volumes: - /etc/localtime:/etc/localtime:ro - /etc/timezone:/etc/timezone:ro - ./zbx_data/usr/lib/zabbix/alertscripts:/usr/lib/zabbix/alertscripts:ro - ./zbx_data/usr/lib/zabbix/externalscripts:/usr/lib/zabbix/externalscripts:ro - ./zbx_data/var/lib/zabbix/modules:/var/lib/zabbix/modules:ro - ./zbx_data/var/lib/zabbix/enc:/var/lib/zabbix/enc:ro - ./zbx_data/var/lib/zabbix/ssh_keys:/var/lib/zabbix/ssh_keys:ro - ./zbx_data/var/lib/zabbix/mibs:/var/lib/zabbix/mibs:ro - ./zbx_data/var/lib/zabbix/snmptraps:/var/lib/zabbix/snmptraps:ro links: - mysql-server:mysql-server - zabbix-java-gateway:zabbix-java-gateway ulimits: nproc: 65535 nofile: soft: 20000 hard: 40000 deploy: resources: limits: cpus: '4' memory: 3G reservations: cpus: '3' memory: 2G env_file: - .env_db_mysql - .env_srv user: root depends_on: - mysql-server - zabbix-java-gateway - zabbix-snmptraps networks: zbx_net: aliases: - zabbix-server - zabbix-server-mysql - zabbix-server-centos-mysql - zabbix-server-mysql-centos zbx_net: stop_grace_period: 30s sysctls: - net.ipv4.ip_local_port_range=1024 65000 - net.ipv4.conf.all.accept_redirects=0 - net.ipv4.conf.all.secure_redirects=0 - net.ipv4.conf.all.send_redirects=0 labels: com.zabbix.description: "Zabbix server with MySQL database support" com.zabbix.company: "Zabbix SIA" com.zabbix.component: "zabbix-server" com.zabbix.dbtype: "mysql" com.zabbix.os: "centos" zabbix-web-nginx-mysql: image: docker-registry.hexun.com/system_ops/zabbix-web-nginx-mysql:centos-4.0-latest ports: - "80:80" - "443:443" links: - mysql-server:mysql-server - zabbix-server:zabbix-server volumes: - /etc/localtime:/etc/localtime:ro - /etc/timezone:/etc/timezone:ro - ./zbx_data/etc/ssl/nginx:/etc/ssl/nginx:ro deploy: resources: limits: cpus: '4' memory: 3G reservations: cpus: '2' memory: 2G env_file: - .env_db_mysql - .env_web user: root depends_on: - mysql-server - zabbix-server healthcheck: test: ["CMD", "curl", "-f", "http://localhost"] interval: 10s timeout: 5s retries: 3 start_period: 30s networks: zbx_net: aliases: - zabbix-web-nginx-mysql - zabbix-web-nginx-centos-mysql - zabbix-web-nginx-mysql-centos zbx_net: stop_grace_period: 10s sysctls: - net.core.somaxconn=65535 labels: com.zabbix.description: "Zabbix frontend on Nginx web-server with MySQL database support" com.zabbix.company: "Zabbix SIA" com.zabbix.component: "zabbix-frontend" com.zabbix.webserver: "nginx" com.zabbix.dbtype: "mysql" com.zabbix.os: "centos" zabbix-java-gateway: image: docker-registry.hexun.com/system_ops/zabbix-java-gateway:centos-4.0-latest ports: - "10052:10052" deploy: resources: limits: cpus: '0.5' memory: 512M reservations: cpus: '0.25' memory: 256M env_file: - .env_java user: root networks: zbx_net: aliases: - zabbix-java-gateway - zabbix-java-gateway-centos stop_grace_period: 5s labels: com.zabbix.description: "Zabbix Java Gateway" com.zabbix.company: "Zabbix SIA" com.zabbix.component: "java-gateway" com.zabbix.os: "centos" zabbix-snmptraps: image: docker-registry.hexun.com/system_ops/zabbix-snmptraps:centos-4.0-latest ports: - "162:162/udp" volumes: - ./zbx_data/var/lib/zabbix/snmptraps:/var/lib/zabbix/snmptraps:rw deploy: resources: limits: cpus: '0.5' memory: 256M reservations: cpus: '0.25' memory: 128M user: root networks: zbx_net: aliases: - zabbix-snmptraps zbx_net: stop_grace_period: 5s labels: com.zabbix.description: "Zabbix snmptraps" com.zabbix.company: "Zabbix SIA" com.zabbix.component: "snmptraps" com.zabbix.os: "ubuntu" mysql-server: image: docker-registry.hexun.com/system_ops/mysql:5.7.26 command: [mysqld, --character-set-server=utf8, --collation-server=utf8_bin, --default-authentication-plugin=mysql_native_password] volumes: - ./zbx_data/var/lib/mysql:/var/lib/mysql:rw env_file: - .env_db_mysql deploy: resources: limits: cpus: '4' memory: 3G reservations: cpus: '3' memory: 2G ports: - "3306:3306" user: root stop_grace_period: 1m networks: zbx_net: aliases: - mysql-server - zabbix-database - mysql-database db_data_mysql: image: busybox volumes: - ./zbx_data/var/lib/mysql:/var/lib/mysql:rw networks: zbx_net: driver: bridge driver_opts: com.docker.network.enable_ipv6: "false"
三、編寫各個容器對應的env_file環境變量文件
3.1：編寫mysql對應env_file文件
#vim /data/zabbix-system/zabbix-apps/.env_db_mysql
# DB_SERVER_HOST=mysql-server # DB_SERVER_PORT=3306 # MYSQL_USER=zabbix MYSQL_USER=zabbix # MYSQL_PASSWORD=zabbix MYSQL_PASSWORD=4Z8tQ5hbXIxR4be # MYSQL_ROOT_PASSWORD= MYSQL_ROOT_PASSWORD=4Z8tQ5hbXIxR4be # MYSQL_ALLOW_EMPTY_PASSWORD=false # MYSQL_DATABASE=zabbix MYSQL_DATABASE=zabbix #增大最大連接數 #show variables like 'max_connections';(查可以看當前的最大連接數) # # set global max_connections=1000; # max_connections=1500 # innodb_buffer_pool_instances=5 # innodb_buffer_pool_size=6G # key_buffer_size=6G
3.2: 設置zabbix-server容器的env_file環境變量
# vim /data/zabbix-system/zabbix-apps/.env_srv
ZBX_LISTENIP=127.0.0.1 ZBX_STARTPOLLERS=30 ZBX_IPMIPOLLERS=1 ZBX_STARTPREPROCESSORS=30 ZBX_STARTPOLLERSUNREACHABLE=30 ZBX_STARTTRAPPERS=30 ZBX_STARTPINGERS=20 ZBX_STARTDISCOVERERS=20 ZBX_STARTHTTPPOLLERS=20 ZBX_STARTTIMERS=20 ZBX_STARTESCALATORS=30 ZBX_STARTALERTERS=20 ZBX_JAVAGATEWAY_ENABLE=true ZBX_JAVAGATEWAY=zabbix-java-gateway ZBX_JAVAGATEWAYPORT=10052 ZBX_STARTJAVAPOLLERS=1 ZBX_STARTVMWARECOLLECTORS=1 ZBX_VMWAREFREQUENCY=50 ZBX_VMWAREPERFFREQUENCY=60 ZBX_VMWARECACHESIZE=80M ZBX_VMWARETIMEOUT=10 ZBX_ENABLE_SNMP_TRAPS=true ZBX_HOUSEKEEPINGFREQUENCY=6 ZBX_MAXHOUSEKEEPERDELETE=200000 ZBX_SENDERFREQUENCY=30 ZBX_CACHESIZE=4024M ZBX_CACHEUPDATEFREQUENCY=60 ZBX_STARTDBSYNCERS=30 ZBX_HISTORYCACHESIZE=2048M ZBX_HISTORYINDEXCACHESIZE=888M ZBX_TRENDCACHESIZE=888M ZBX_VALUECACHESIZE=4096M ZBX_TIMEOUT=30 ZBX_TRAPPERIMEOUT=300 ZBX_UNREACHABLEPERIOD=45 ZBX_UNAVAILABLEDELAY=60 ZBX_UNREACHABLEDELAY=1 ZBX_LOGSLOWQUERIES=3000 ZBX_STARTPROXYPOLLERS=20 ZBX_PROXYCONFIGFREQUENCY=600 ZBX_PROXYDATAFREQUENCY=1
3.3:設置Nginx-web容器的env_file環境變量
#vim /data/zabbix-system/zabbix-apps/.env_web
ZBX_SERVER_HOST=192.168.60.100 ZBX_SERVER_PORT=10051 ZBX_SERVER_NAME=tjdl-zabix-server ZBX_MAXEXECUTIONTIME=600 ZBX_MEMORYLIMIT=512M ZBX_POSTMAXSIZE=50M ZBX_UPLOADMAXFILESIZE=2M ZBX_MAXINPUTTIME=300 ZBX_SESSION_NAME=zbx_sessionid PHP_TZ=Asia/Shanghai
3.4: 設置java-gateway容器環境變量
# vim /data/zabbix-system/zabbix-apps/.env_java
ZBX_START_POLLERS=5 ZBX_TIMEOUT=3 # Possible values: trace, debug, info, want, error, all, off ZBX_DEBUGLEVEL=info
以上編寫好yaml文件以及環境變量，可嘗試重啓各個容器服務組件，
[root@hostname-60100 zabbix-apps]#docker-compose -f zabbix-apps-compose.yaml up -d#創建容器並啓動 WARNING: Some services (mysql-server, zabbix-java-gateway, zabbix-server, zabbix-snmptraps, zabbix-web-nginx-mysql) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm. Restarting zabbix-apps_zabbix-web-nginx-mysql_1 ... done Restarting zabbix-apps_zabbix-server_1 ... done Restarting zabbix-apps_mysql-server_1 ... done Restarting zabbix-apps_zabbix-snmptraps_1 ... done Restarting zabbix-apps_db_data_mysql_1 ... done Restarting zabbix-apps_zabbix-java-gateway_1 ... done
檢查一下docker容器是否都正常啓動，如果有容器無法正常啓動，可查看某個容器日誌進行排錯，例如下面的zabbix-server沒有啓動，爲退出狀態
報錯：connenction to database 'zabbix' failed: too many connections
docker-compose -f zabbix-apps-compose.yaml logs -f zabbix-server #查看容器日誌
# docker exec -it zabbix-apps_mysql-server_1 bash 可進入mysql容器設置默認最大連接數
root@fdbebd4882df:/# egrep -v "#|^$" etc/mysql/mysql.conf.d/mysqld.cnf #增加max_connections=1000參數，修改配置文件之後需重啓mysql服務，因爲mysql已經容器化，需要重啓生效即可
[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
symbolic-links=0
max_connections=1000
Ps:還有一種方法可以在mysql命令行中設置最大連接數，但只是臨時生效（set global max_connections=1000；）
mysql> show variables like 'max_connections'; #查看mysql最大連接數；
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| max_connections | 1000 |
+-----------------+-------+
1 row in set (0.00 sec)
最後再次查看zabbix-server容器日誌，已經沒有異常信息提示
#docker-compose -f zabbix-apps-compose.yaml logs -ft zabbix-server
四：進入lnmp容器修改php對應的配置文件
#docker exec -it zabbix-apps_zabbix-web-nginx-mysql_1 bash
#cat /usr/share/zabbix/conf/zabbix.conf.php #注意這裏的php配置文件一定要與前面之前編寫的.env_srv環境內容對應 <?php // Zabbix GUI configuration file. global $DB, $HISTORY; $DB['TYPE'] = 'MYSQL'; $DB['SERVER'] = 'mysql-server'; $DB['PORT'] = '3306'; $DB['DATABASE'] = 'zabbix'; $DB['USER'] = 'zabbix'; $DB['PASSWORD'] = '4Z8tQ5hbXIxR4be'; // Schema name. Used for IBM DB2 and PostgreSQL. $DB['SCHEMA'] = ''; $ZBX_SERVER = '192.168.60.100'; $ZBX_SERVER_PORT = '10051'; $ZBX_SERVER_NAME = 'tjdl-zabix-server'; $IMAGE_FORMAT_DEFAULT = IMAGE_FORMAT_PNG; // Elasticsearch url (can be string if same url is used for all types). $HISTORY['url'] = ''; // Value types stored in Elasticsearch. $HISTORY['types'] = [];
當一切配置修改完畢之後，再次通過docker-compose啓動各個容器組件，確保每個配置均已生效
docker-compose -f zabbix-apps-compose.yaml restart
訪問zabbix監控url：http://192.168.60.100/zabbix.php?action=dashboard.view
五、更新本地agent端配置：
#docker inspect zabbix-apps_zabbix-server_1 | grep -i ipaddr #查看zabbix-server容器的IP地址，此IP用於agent配置文件中的server地址 "SecondaryIPAddresses": null, "IPAddress": "", "IPAddress": "172.18.0.2",
agent配置文件如下：
[root@hostname-60100 zabbix-apps]# egrep -v "#|^$" /etc/zabbix/zabbix_agentd.conf PidFile=/run/zabbix/zabbix_agentd.pid LogFile=/var/log/zabbix/zabbix_agentd.log LogFileSize=0 Server=172.18.0.2 ListenIP=192.168.60.100 Include=/etc/zabbix/zabbix_agentd.d/*.conf1
#systemctl restart zabbix-agent #重啓zabbix-agent
如果agent端監控成功，那麼zabbixserver端獲取的圖形式亂碼狀態，需要中文亂碼問題
、
#docker cp DejaVuSans.ttf zabbix-apps_zabbix-web-nginx-mysql_1:/usr/share/zabbix/assets/fonts/ #將windows下的中文字體拷貝到web容器相應的目錄中，最後重啓容器刷新即可
#docker-compose -f zabbix-apps-compose.yaml restart zabbix-web-nginx-mysql
END!
