Deploy Zabbix database end

• Install Database Program

yum install -y mariadb mariadb-server

• Modify Profile

vim /etc/my.cnf
#
[mysqld]
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
innodb_file_per_table=1
max_connections=10000
skip_name_resolve=1

• Start the service and view port status

systemctl start mysqld
ss -tnl

• Log in to mysql, create users, and grant permissions

CREATE DATABASE zabbix CHARACTER SET utf8 COLLATE utf8_bin;
GARNT ALL ON zabbix.* TO zabbix@'172.16.50.%' IDENTIFIED BY '123456';

• Create soft links for mysql pid files

ln -sv /var/lib/mysql/mysql.sock /tmp/mysql.sock

Testing the ability to log in to mysql on the server side of the agent

mysql -uzabbix -p123456 -h172.16.50.15

1. Deploy the zabbix Server side

• Install Base Dependency Package

yum install gcc libxml2-devel netsnmp net-snmp-devel crul curl-devel php php-bcmath php-mbstring mariadb mariadb-devel mariadb-server 

• Compile and install zabbix

tar xvf zabbix-3.0.10.tar.gz
cd zabbix-3.0.10/
./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl --with-libxml2 --enable-java
make && make install

• Copy zabbix startup script

cp /usr/local/src/zabbix-3.0.10/misc/init.d/fedora/core/* /etc/init.d/

• Modify startup script

  1. Modify server script

vim /etc/init.d/zabbix_server
#Modify the following items

# Modify the path of zabbix
BASEDIR=/usr/local/zabbix

# Modify start function
start() {
        if [ $RUNNING -eq 1 ] 
                then
                echo "$0 $ARG: $BINARY_NAME (pid $PID) already running"
        else
                action $"Starting $BINARY_NAME: " $FULLPATH -c /usr/local/zabbix/etc/zabbix_agentd.conf
                touch /var/lock/subsys/$BINARY_NAME
    fi  
}

Restart the zabbix_server service

/etc/init.d/zabbix_server stop
systemctl daemon-reload
/etc/init.d/zabbix_server start
/usr/local/zabbix/sbin/zabbix_server

1. Modify agent script

vim /etc/init.d/zabbix_agentd
#Modify the following items

# Modify the path of zabbix
BASEDIR=/usr/local/zabbix

# Modify start function
start() {
        if [ $RUNNING -eq 1 ]
                then
                echo "$0 $ARG: $BINARY_NAME (pid $PID) already running"
        else
                action $"Starting $BINARY_NAME: " $FULLPATH -c /usr/local/zabbix/etc/zabbix_agentd.conf
                touch /var/lock/subsys/$BINARY_NAME
        fi
}

Restart the zabbix_agentd service

/etc/init.d/zabbix_agentd stop
systemctl daemon-reload
/etc/init.d/zabbix_server start

• Import the specified.sql files sequentially into the created'zabbix'database

cd zabbix-3.0.10/
#Import the first.sql file
mysql -uzabbix -p123456 -h172.16.50.15 zabbix < database/mysql/schema.sql 
#Import the second file
mysql -uzabbix -p123456 -h172.16.50.15 zabbix < database/mysql/images.sql
#Import the third file
mysql -uzabbix -p123456 -h172.16.50.15 zabbix < database/mysql/data.sql

• Create zabbix users and groups

groupadd zabbix
useradd -g zabbix -s /sbin/nologin zabbix

• Create zabbix log directory and modify directory permissions

mkdir  /var/log/zabbix
chown -R zabbix.zabbix /var/log/zabbix

2. Deploy the Zabbix agent side

Install Base Dependency Package

yum install gcc

tar xvf zabbix-3.0.10.tar.gz
cd /usr/local/src/zabbix-3.0.10
./configure --prefix=/usr/local/zabbix --enable-agent
make -j 4 && make install

Copy and modify service startup scripts

cp misc/init.d/fedora/core/zabbix_agentd  /etc/init.d/
vim /etc/init.d/zabbix_agentd
BASEDIR=/usr/local/zabbix

Create zabbix users and modify configuration files

useradd  zabbix -s /sbin/nologin 
vim /usr/local/zabbix/etc/zabbix_agentd.conf
#Modify the following items
LogFile=/tmp/zabbix_agentd.log
DebugLevel=4
Server=172.16.50.1
Hostname=172.16.50.14   #The server side must write this name when adding this server

Start Services

/usr/local/zabbix/sbin/zabbix_agentd  -c /usr/local/zabbix/etc/zabbix_agentd.conf
/etc/init.d/zabbix_agentd start
ss -tnl
#
LISTEN     0      128      *:10050     *:* 

3. Configure java gateway to monitor tomcat class services

Prepare packages

mv jdk-7u79-linux-x64.tar.gz apache-tomcat-7.0.68.tar.gz /usr/local/src
cd /usr/local/src

Install jdk

tar xvf jdk-7u79-linux-x64.tar.gz
cd jdk1.7.0_79/
ln -sv /usr/local/src/jdk1.7.0_79/ /usr/local/jdk

Modify environment variables

vim /etc/profile
#Add the following lines at the end
export JAVA_HOME=/usr/local/jdk
export TOMCAT_HOME=/usr/local/tomcat
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$TOMCAT_HOME/bin:$PATH
export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar
#Overload the file
source /etc/profile
#Test whether the configuration is correct
java -version
#Configuration is correct when shown below
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

Install tomcat

tar xvf apache-tomcat-7.0.68.tar.gz 
ln -sv /usr/local/src/apache-tomcat-7.0.68 /usr/local/tomcat

Modify tomcat configuration file

vim /usr/local/tomcat/bin/catalina.sh
#Modify the following
CATALINA_OPTS="$CATALINA_OPTS 
-Dcom.sun.management.jmxremote  
-Dcom.sun.management.jmxremote.port=12345   
-Dcom.sun.management.jmxremote.authenticate=false  
-Dcom.sun.management.jmxremote.ssl=false 
-Djava.rmi.server.hostname=172.16.50.14" 

Restart tomcat service

/usr/local/tomcat/bin/catalina.sh stop
/usr/local/tomcat/bin/catalina.sh start
#View port 12345
ss -tnl
State       Recv-Q Send-Q Local Address:Port        Peer Address:Port                              
LISTEN      4      100       :::8080                :::*                                    
LISTEN      0      50        :::12345               :::*                                                      
LISTEN      0      100       :::8009                :::*

Execute on the zabbix_server host:

Modify Profile

vim /usr/local/zabbix/sbin/zabbix_java/settings.sh
#Modify the following items
LISTEN_IP="0.0.0.0"
LISTEN_PORT=10052
PID_FILE="/tmp/zabbix_java.pid"
START_POLLERS=25
TIMEOUT=30

Start the zabbix_java service

/usr/local/zabbix/sbin/zabbix_java/startup.sh
ss -tnl
LISTEN      0      50      :::10052     :::*

Modify the main zabbix_server configuration file

vim /usr/local/zabbix/etc/zabbix_server.conf
#Modify the following items
JavaGateway=172.16.50.14
JavaGatewayPort=10052
StartJavaPollers=25
Timeout=30

Restart the zabbix_server service

/etc/init.d/zabbix_server restart
ss -tnl
#
LISTEN      0      128           *:10051 

Deploy zabbix_agent service on tomcat host

Follow the steps in this paragraph 2. Deploy the Zabbix agent side

4. Configure Web GUI pages

Install httpd

yum install -y httpd

Prepare resources

mkdir /var/www/html/zabbix
cp -a /usr/local/src/zabbix-3.0.10/frontends/php/* /var/www/html/zabbix

Start the service and set it to Start Up

systemctl start httpd
systemctl enable httpd

Use browser access http://172.16.50.1/zabbix

The first time you visit this page, there may be some errors after clicking next. You can install the following packages and restart the httpd service

yum install php-common php-xmlreader php-xmlwriter php-xml php-net-socket php-gd php-mysql php-ldap

systemctl restart httpd

There may still be some errors, you can modify the php configuration file

vim /etc/php.ini
#
post_max_size = 16M
max_execution_time = 300
max_input_time = 300
date.timezone = Aisa/Shanghai

find / -name Shanghai
#The result is
/usr/share/zoneinfo/Asia/Shanghai
/usr/share/zoneinfo/posix/Asia/Shanghai
/usr/share/zoneinfo/right/Asia/Shanghai
/usr/share/javazi/Asia/Shanghai

Restart httpd again, then click Next and follow the instructions.

Download the file zabbix.conf.php as prompted to execute the command:

cp zabbix.conf.php /var/www/html/zabbix/conf/zabbix.conf.php

The default login user name for the ZABBIX page is Admin, and the password is zabbix. After login, change the language to Simplified Chinese.

Chinese may be garbled and fonts need to be installed to copy simkai.ttf to/var/www/html/zabbix/fonts/directory from the windows system directory C:\Windows\Fonts path

cd /var/www/html/zabbix/fonts/
#Select a font file and use the rz command to upload the font file in.tty format to this directory
#Modify Profile
vim /var/www/html/zabbix/include/defines.inc.php
#Modify the following
define('ZBX_GRAPH_FONT_NAME',           'simkai'); // font file name

To enable monitoring of the native state of zabbix_server, turn on the zabbix_agent service for the server host

/etc/init.d/zabbix_agentd start
Starting zabbix_agentd (via systemctl):                    [  OK  ]
ss -tnl
LISTEN      0      128        *:10050           *:* 

Click Configuration -> Host -> View Zabbix server -> Click Status Field''Deactivated''-> Confirm Native Enabled -> Status Field becomes''Enabled''.
