十一、安装配置zabbix，并实现zabbix监控tomcat，nginx，memcached，redis等，并实现发生报警后发送邮件报警

1、安装配置zabbix

1.1 环境准备

Ubuntu 18.04 ：192.168.7.101  zabbix server

Ubuntu 18.04 ：192.168.7.102  mysql

Ubuntu 18.04 ：192.168.7.103  tomcat

1.2 准备mysql（192.168.7.102）

<root@ubuntu182 ~>#apt install mysql-server

<root@ubuntu182 ~>#mysql

mysql> create database zabbix character set utf8 collate utf8_bin;

Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on zabbix.* to zabbix@"192.168.7.%" identified by '123456';

Query OK, 0 rows affected, 1 warning (0.00 sec)

<root@ubuntu182 ~>#vim /etc/mysql/mysql.conf.d/mysqld.cnf

bind-address            = *

<root@ubuntu182 ~>#systemctl restart mysql

1.3 安装配置zabbix

上传配置

1.4 设置中文界面

看系统内安装的locale：locale -a

若未装入中文语言包，安装zh_CN.UTF-8：locale-gen zh_CN.UTF-8

<root@ubuntu181 conf>#sudo dpkg-reconfigure locales

<root@ubuntu181 conf>#vim /var/www/html/include/locales.inc.php

'zh_CN' => ['name' => _('Chinese (zh_CN)'),     'display' => true]

1.5 解决中文乱码

将:\Windows\Fonts中文字体导入/var/www/html/fonts目录中：SIMSUN.TTC

<root@ubuntu181 fonts>#vim /var/www/html/include/defines.inc.php

define('ZBX_GRAPH_FONT_NAME',           'DejaVuSans');

define('ZBX_FONT_NAME', 'DejaVuSans');

修改为

define('ZBX_GRAPH_FONT_NAME',           'SIMSUN');

define('ZBX_FONT_NAME', 'SIMSUN');

2、监控tomcat（待完成）

2.1 配置zabbix服务端

<root@ubuntu181 ~>#grep "^[a-Z]" /usr/local/zabbix/sbin/zabbix_java/settings.sh

LISTEN_IP="0.0.0.0"

LISTEN_PORT=10052

PID_FILE="/tmp/zabbix_java.pid"

START_POLLERS=20

TIMEOUT=15

#启动

<root@ubuntu181 ~>#chmod a+x /usr/local/zabbix/sbin/zabbix_java/*

<root@ubuntu181 ~>#cd /usr/local/zabbix/sbin/zabbix_java

<root@ubuntu181 zabbix_java>#sh startup.sh

#配置zabbix server调用java gateway

<root@ubuntu181 zabbix_java>#grep "^[a-Z]" /usr/local/zabbix/etc/zabbix_server.conf

LogFile=/var/log/zabbix/zabbix_server.log

PidFile=/usr/local/zabbix/run/zabbix_server.pid

DBHost=192.168.7.102

DBName=zabbix

DBUser=zabbix

DBPassword=123456

DBPort=3306

JavaGateway=192.168.7.101

JavaGatewayPort=10052

StartJavaPollers=20

Timeout=30

LogSlowQueries=3000

<root@ubuntu181 zabbix>#systemctl restart zabbix-server

2.2 配置tomcat （192.168.7.103 ）

<root@ubuntu183 ~>#apt install openjdk-8-jdk tomcat8 -y

<root@ubuntu183 ~>#vim /usr/share/tomcat8/bin/catalina.sh

CATALINA_OPTS="$CATALINA_OPTS

-Dcom.sun.management.jmxremote

-Dcom.sun.management.jmxremote.authenticate=false

-Dcom.sun.management.jmxremote.ssl=false

-Dcom.sun.management.jmxremote.port=12345

-Djava.rmi.server.hostname=192.168.7.103"

<root@ubuntu183 ~>#/usr/share/tomcat8/bin/catalina.sh stop

<root@ubuntu183 ~>#/usr/share/tomcat8/bin/catalina.sh start

2.3配置zabbix客户端

#安装相关依赖

<root@ubuntu181 src>#apt install libmysqld-dev  libmysqlclient-dev  libxml2-dev  libxml2 snmp  libsnmp-dev   libevent-dev  curl  libcurl4-openssl-dev -y

#编译安装zabbix

<root@ubuntu181 src>#cd /usr/local/src/

<root@ubuntu181 src>#wget https://cdn.zabbix.com/zabbix/sources/stable/4.0/zabbix-4.0.24.tar.gz

<root@ubuntu181 src>#tar xvf zabbix-4.0.24.tar.gz

<root@ubuntu181 src>#cd zabbix-4.0.24/

<root@ubuntu181 zabbix-4.0.24># ./configure --enable-agent --prefix=/usr/local/zabbix

#编辑zabbix_agentd.conf配置文件

<root@ubuntu183 zabbix-4.0.24>#grep "^[a-Z]" /usr/local/zabbix/etc/zabbix_agentd.conf

LogFile=/tmp/zabbix_agentd.log

Server=192.168.7.101

ServerActive=127.0.0.1

Hostname=192.168.7.103

<root@ubuntu183 zabbix-4.0.24>#/usr/local/zabbix/sbin/zabbix_agentd -c /usr/local/zabbix/etc/zabbix_agentd.conf

2.4 下载工具包测试
