安装zabbix监控服务

一、架构设计

1.服务器准备

二、数据库准备

1.主服务器安装配置mariadb-server

yum -y install mariadb-server

vim   /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
server_id=163
innodb_file_per_table=ON
innodb_buffer_pool_size=256M
max_connections=2000
log_bin=/var/log/mariadb/log_bin
skip_name_resolve
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
!includedir /etc/my.cnf.d

systemctl start mariadb
mysql_secure_installation

2.mariadb从服务器安装配置

grant replication slave,replication client on *.* to  slave@'192.168.17.173' identified by 'slave';

#查看当前二进制日志事务位置
show master status;
log_bin.000001 |      418

yum -y install mariadb-server

vim   /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
server_id=173
relay_log=/var/log/mariadb/log_relog
log_bin=/var/log/mariadb/log_bin
log_slave_updates=1
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
!includedir /etc/my.cnf.d

systemctl start mariadb
mysql_secure_installation

change master to master_host='192.168.16.173', master_user='slave', master_password='slave', master_log_file='log_bin.000001',master_log_pos=418;

start slave;

3.sql语句创建zabbix的数据库和用户

MariaDB [(none)]> create database zabbixdb character set 'utf8';

MariaDB [(none)]> grant all on zabbixdb.* to zabbix@'192.168.17.%' identified by 'zabbix';
或grant all on zabbixdb.* to zabbix@'localhost' identified by 'zabbix';

二、zabbix-server安装并初始化数据库

1..安装zabbix-server

1.下载安装epel源程序包，会自动生成对应的epel源 http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm rpm -ih  zabbix-release-3.4-2.el7.noarch.rpm
2.安装相应zabbix程序包
yum clean all
yum repolist

yum install
zabbix-server-mysql-3.2.6-1.el7.x86_64.rpm
zabbix-web-3.2.6-1.el7.noarch.rpm
zabbix-web-mysql-3.2.6-1.el7.noarch.rpm
zabbix-agent-3.2.6-1.el7.x86_64.rpm
zabbix-get-3.2.6-1.el7.x86_64.rpm
zabbix-sender-3.2.6-1.el7.x86_64.rpm

yum install
zabbix-server-mysql-3.2.6-1.el7.x86_64.rpm
zabbix-web-3.2.6-1.el7.noarch.rpm
zabbix-web-mysql-3.2.6-1.el7.noarch.rpm
zabbix-agent-3.2.6-1.el7.x86_64.rpm
zabbix-get-3.2.6-1.el7.x86_64.rpm
zabbix-sender-3.2.6-1.el7.x86_64.rpm

2.初始化数据库

rpm -ql zabbix-server-mysql
cp /usr/share/doc/zabbix-server-mysql-3.2.6/create.sql.gz .
gzip -d create.sql.gz

mysql -uzabbix -pzabbix zabbixdb <create.sql

3.配置zabbix-server

vim  /etc/zabbix/zabbix_server.conf
修改
ListenPort=10051
SourceIP=192.168.16.173
LogFile=/var/log/zabbix/zabbix_server.log
LogFileSize=1
DebugLevel=3
PidFile=/var/run/zabbix/zabbix_server.pid
DBHost=localhost
DBName=zabbixdb
DBUser=zabbix
DBPassword=zabbix
#mysql为localhost或127.0.0.1的话，需要设置DBSocket
DBSocket=/var/lib/mysql/mysql.sock
DBPort=3306

systemctl  start zabbix-server

三、配置web界面

配置httpd相关

vim   /etc/httpd/conf.d/zabbix.conf

#映射 URL /zabbix 到  /usr/share/zabbix
Alias /zabbix /usr/share/zabbix
<Directory "/usr/share/zabbix">
Options FollowSymLinks
AllowOverride None
Require all granted

<IfModule mod_php5.c>
php_value max_execution_time 300
php_value memory_limit 128M
php_value post_max_size 16M
php_value upload_max_filesize 2M
php_value max_input_time 300
php_value always_populate_raw_post_data -1
#时区；在此设置对zabbbix有效；在/etc/php.ini下全部php有效
php_value date.timezone Asia/Shanghai
</IfModule>
</Directory>

<Directory "/usr/share/zabbix/conf">
Require all denied
</Directory>

<Directory "/usr/share/zabbix/app">
Require all denied
</Directory>

<Directory "/usr/share/zabbix/include">
Require all denied
</Directory>

<Directory "/usr/share/zabbix/local">
Require all denied
</Directory>

systemctl  start httpd
