Zabbix3.2.11 source compiler installation for centos7

This article reprinted from: https://www.93bok.com

A, Linux briefly popular open source monitoring system

cacti：存储数据能力强，报警性能差
nagios：报警性能差，存储数据仅有简单的一段可以判断是否在合理范围内的数据长度，储存在内存中。比如，连续采样数据存储，有连续三次不在合理范围内的数据就报警
zabbix：结合上面两种工具的优点，又可以存储数据，又可以报警。

Two, Zabbix component functionality

Server

• Zabbix server is monitoring agent reporting system availability, system integrity and complete the core components of statistical information. Zabbix Server is all the configuration information, core memory statistics and operational data.

Database storage

• All data collected Zabbix configuration information and are stored in a database.

Web Interface

• For any platform from anywhere and have easy access to Zabbix, Zabbix provides a Web-based interface. The interface is part of Zabbix Server, usually (but not necessarily) with Zabbix Server running on the same physical machine.

• If you are using SQLite, Zabbix Web interface must keep Zabbix Server running on the same physical machine.

Proxy Proxy

• Zabbix proxy can collect performance and availability data for Zabbix Server. Proxy A proxy server is optional part of Zabbix software deployment; of course, Proxy proxy server can help a single Zabbix Server to share the load pressure.

Agent monitoring agent

• Zabbix agents monitoring agent monitors deployed on the target that actively monitor local resources and applications, and the data collected is reported to Zabbix Server.

data flow

• In addition, understanding of internal Zabbix data flows equally important. To create a monitored item used to collect data, you must first create a host. Conversion to other parts of Zabbix function, you must first have a monitored item to create a trigger, you must have a trigger to create action. So, if you want to receive the X server CPU load is too high alarm, you must first create a host entity for the X server and associated with a CPU for monitoring items monitored, and if the CPU load is too high will activate the trigger and then perform an action, send you e-mail alerts.

Three, Zabbix operating mechanism

Zabbix monitoring process can be simply described as:

• Data acquisition -> data storage -> Data Analysis -> Display Data -> Alarm Monitor

Monitoring works:

• ZabbixAgent services related to data transfer from the system to get ZabbixServer, then after analyzing PHP page to show the data out ZabbixServer Service Award

• Zabbix supports a variety of monitoring the network, it can be distributed by the deployment and installation Zabbix monitoring agent, collecting data by C / S mode, B / S model and display the Web terminal configuration! Agent monitoring port 10050

Six, Zabbix source compiler installation

(A) build environment LNMP

Skip the detailed process before can refer to the article "Centos7.2 LNMP source compiler environment"

(B) source compiler installed Zabbix for server terminal

1. Modify the php.ini configuration file

vim /etc/php/php.ini

date.timezone = Asia/Shanghai
post_max_size = 16M
max_execution_time = 300
max_input_time = 300

2. Create the Zabbix database

mysql -u root -p123456

mysql> create database zabbix;
mysql> grant all on zabbix.* to zabbix@'localhost' identified by 'nongkaige';
mysql> flush privileges;

3. Test user can log database using zabbix

mysql -u zabbix -pnongkaige

4. Import Zabbix database

• Import zabbix database architecture that has been the source package, first unpack the source package zabbix

cd /a01/apps/apps_src/
tar -zxvf zabbix-3.2.11.tar.gz

• It must be introduced in order:

mysql -u zabbix -pnongkaige zabbix < /a01/apps/apps_src/zabbix-3.2.11/database/mysql/schema.sql
mysql -u zabbix -pnongkaige zabbix < /a01/apps/apps_src/zabbix-3.2.11/database/mysql/images.sql
mysql -u zabbix -pnongkaige zabbix < /a01/apps/apps_src/zabbix-3.2.11/database/mysql/data.sql

5. Installation source compiler zabbix

1) Create a zabbix run user (if you start zabbix process as root, it will automatically switch to zabbix users)

useradd -M -s /sbin/nologin zabbix

2) install dependencies

cd /a01/apps/apps_src/zabbix-3.2.11
yum -y install libevent-devel libxml2-devel libcurl-devel net-snmp-devel

3) compile zabbix

./configure --prefix=/a01/apps/zabbix --sysconfdir=/etc/zabbix --datadir=/a01/apps/zabbix/data --enable-server --enable-agent --enable-java --with-mysql --with-net-snmp --with-libcurl --with-libxml2

• Note: It is best to bring --enable-java compile-time parameters, to facilitate future monitoring program tomcat with time.

4) install java

• 报错：configure: error: Unable to find "javac" executable in path

• Not installed java environment, to install what you can

cd /a01/apps/apps_src/
mkdir -p /usr/local/java
tar -zxvf jdk-8u151-linux-x64.tar.gz -C /usr/local/java/
vim /etc/profile

JAVA_HOME=/usr/local/java/jdk1.8.0_151
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=$JAVA_HOME/jre/lib/ext:$JAVA_HOME/lib/tools.jar
export PATH JAVA_HOME CLASSPATH

source /etc/profile
java -version

• Continue compiled after installing java

5) Installation

make install

6) Create a log directory zabbix

mkdir -p /var/log/zabbix
chown -R zabbix:zabbix /var/log/zabbix/

7) Configuration zabbix_server profile

vim /etc/zabbix/zabbix_server.conf

LogFile=/var/log/zabbix/zabbix_server.log
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=nongkaige

8) zabbix_agent configuration profiles to achieve their own monitoring

vim /etc/zabbix/zabbix_agentd.conf

LogFile=/var/log/zabbix/zabbix_agentd.log
Server=127.0.0.1
ServerActive=127.0.0.1
Hostname=Zabbix server
UnsafeUserParameters=1      #允许所有的字符是在用户定义的参数，参数传递，也就是支持自定义脚本

9) Start zabbix

/a01/apps/zabbix/sbin/zabbix_server -c /etc/zabbix/zabbix_server.conf
/a01/apps/zabbix/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf

• 报错：error while loading shared libraries: libmysqlclient.so.20: cannot open shared object file: No such file or directory

• Probably means can not find libmysqlclient.so.20, we see mysql installation directory should be a soft link up to:

ln -s /a01/apps/mysql/lib/libmysqlclient.so.20 /usr/local/lib
vim /etc/ld.so.conf

/usr/local/lib

• Run ldconfig command take effect after restarting success.

10) configured zabbix web page

mkdir -p /a01/apps/nginx/html/zabbix
cd /a01/apps/apps_src/zabbix-3.2.11/frontends/php/
cp -a . /a01/apps/nginx/html/zabbix/

11) Installation zabbix front end (http: // <server ip or host name> / zabbix)

• First restart the php-fpm

systemctl restart php-fpm

• 报错：PHP sockets extension missing (PHP configuration parameter --enable-sockets).

12) mounting extensions php sockets

• Into the php source package, use the tool to install phpize

cd /a01/apps/apps_src/php-7.1.7/ext/sockets/
/a01/apps/php7/bin/phpize
./configure --with-php-config=/a01/apps/php7/bin/php-config
make && make install
vim /etc/php/php.ini

[sockets]
extension = sockets.so

13) mounting extensions php ldap

yum -y install openldap-devel

• Always perform this step, otherwise the following will error: configure: error: Can not find ldap libraries in / usr / lib.

cp -frp /usr/lib64/libldap* /usr/lib

cd /a01/apps/apps_src/php-7.1.7/ext/ldap/
/a01/apps/php7/bin/phpize
./configure --with-php-config=/a01/apps/php7/bin/php-config
make && make install
vim /etc/php/php.ini

[ldap]
extension = ldap.so

14) Restart php-fpm

systemctl restart php-fpm

15) to refresh the page to continue installing the front zabbix

• Being given, we can put the image above to download the configuration file and then uploaded to the figure down to the specified directory, but zabbix under the web root directory already comes, we can go directly to modify

cd /a01/apps/nginx/html/zabbix/conf
cp zabbix.conf.php.example zabbix.conf.php
vim zabbix.conf.php

16) Next, close your browser will be able to revisit logged (default account: admin, password: zabbix)

17) into Chinese page

18) Modify the default password is nongkaige

19) arranged to monitor the machine

"Configuration" ----- "host" ----- "Enable"

20) Repair Chinese garbled

• Can be found in the figure above situation garbled into some box, we can go to download fonts, font, or go directly to copy some files to upload and modify the configuration on our win7 system.

• 1, go to the Control Panel win7 copy fonts

• 2, copy the font and upload it to the server

• 3, mv font to the specified directory, and modify the configuration file

cd /a01/apps/apps_src/
mv msyh.ttf /a01/apps/nginx/html/zabbix/fonts/
vim /a01/apps/nginx/html/zabbix/include/defines.inc.php

#修改45行
define('ZBX_GRAPH_FONT_NAME',           'msyh'); // font file name
#修改93行
define('ZBX_FONT_NAME', 'msyh');

• 4, refresh the page to see

21) Disable guest user

• "Management" ------ "User Group" ------ "disabled"

22) scripting to add zabbix-server system services

cd /etc/systemd/system
vim zabbix-server.service

[Unit]
Description=zabbix-server
After=network.target

[Service]
Type=forking
ExecStart=/a01/apps/zabbix/sbin/zabbix_server -c /etc/zabbix/zabbix_server.conf

[Install]
WantedBy=multi-user.target

chmod 754 /etc/systemd/system/zabbix-server.service
systemctl enable zabbix-server

23) scripting to add zabbix-agentd to system services

cd /etc/systemd/system
vim zabbix-agentd.service

[Unit]
Description=zabbix-server
After=network.target

[Service]
Type=forking
ExecStart=/a01/apps/zabbix/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf

[Install]
WantedBy=multi-user.target

chmod 754 /etc/systemd/system/zabbix-agentd.service
systemctl enable zabbix-agentd

• Well, this zabbix server has been deployed, and implemented monitoring zabbix the machine, take a look at the following renderings

(C) the client source code to compile and install Zabbix for agent-side for centos 6

1. Create a user runs zabbix

useradd -M -s /sbin/nologin zabbix

2. Unpack

cd /a01/apps/apps_src/
tar -zxvf zabbix-3.2.11.tar.gz
cd zabbix-3.2.11

3. Configuration

./configure --prefix=/a01/apps/zabbix --sysconfdir=/etc/zabbix --datadir=/a01/apps/zabbix/data --enable-agent

4. Install

make install

5. Create a log directory zabbix

mkdir -p /var/log/zabbix
chown -R zabbix:zabbix /var/log/zabbix/

6. Configure zabbix_agentd profile

vim /etc/zabbix/zabbix_agentd.conf

LogFile=/var/log/zabbix/zabbix_agentd.log
Server=192.168.10.21
ServerActive=192.168.10.21
Hostname=192.168.10.26
UnsafeUserParameters=1

7. cp source package comes with a script to add to the system service zabbix-agentd

cp /a01/apps/apps_src/zabbix-3.2.11/misc/init.d/fedora/core5/zabbix_agentd /etc/init.d/
vim /etc/init.d/zabbix_agentd

ZABBIX_BIN="/a01/apps/zabbix/sbin/zabbix_agentd"        #修改
CONF_FILE="/etc/zabbix/zabbix_agentd.conf"              #添加
daemon $ZABBIX_BIN -c $CONF_FILE                        #添加后边的-c $CONF_FILE

chkconfig --add zabbix_agentd
chkconfig --level 35 zabbix_agentd on

8. Start zabbix_agentd

service zabbix_agentd start

(Iv) to test whether the client and server communications zabbix

/a01/apps/zabbix/bin/zabbix_get -s 192.168.10.26 -p10050 -k"net.if.in[eth2,bytes]"

• The server can get information about the client's card, indicating that can communicate

(E) to the front-end web page creation zabbix Host monitoring client

• "Configuration" ------ "host" ------ "Create Host"
