监控服务zabbix5.4.4部署

1.监控服务zabbix部署

环境说明：

环境	IP	要安装的应用
服务器	192.168.237.168	lamp架构 zabbix server zabbix agent
客户端	192.168.237.169	zabbix agent

因为zabbix是用php语言开发的，所以必须先部署lamp架构，使其能够支持运行php网页

1.1 zabbix服务端安装

//安装依赖包
[root@server ~]# yum -y install net-snmp-devel libevent-devel

//下载zabbix
[root@server src]# wget https://cdn.zabbix.com/zabbix/sources/stable/5.4/zabbix-5.4.4.tar.gz

//解压
[root@server src]# tar xf zabbix-5.4.4.tar.gz 
[root@server src]# ls zabbix-5.4.4
aclocal.m4  ChangeLog     config.sub    database  install-sh   man      README
AUTHORS     compile       configure     depcomp   m4           misc     sass
bin         conf          configure.ac  include   Makefile.am  missing  src
build       config.guess  COPYING       INSTALL   Makefile.in  NEWS     ui

//创建用户
[root@server src]# useradd -r -M -s /sbin/nologin zabbix

//配置数据库
mysql> create database zabbix character set utf8 collate utf8_bin;	//创建数据库
Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on zabbix.* to 'zabbix'@'localhost' identified by 'zabbix123!';	//授权用户
Query OK, 0 rows affected, 2 warnings (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

mysql> quit
Bye

//依次导入架构、图片、数据到zabbix数据库
[root@server zabbix-5.4.4]# cd database/
[root@server database]# ls
elasticsearch  Makefile.am  Makefile.in  mysql  oracle  postgresql  sqlite3
[root@server database]# cd mysql/	//使用哪种数据库就进入该数据库目录
[root@server mysql]# ls
data.sql  double.sql  images.sql  Makefile.am  Makefile.in  schema.sql

[root@server mysql]# mysql -uroot -p123 zabbix < schema.sql 	//导入架构
mysql: [Warning] Using a password on the command line interface can be insecure.
[root@server mysql]# mysql -uroot -p123 zabbix < images.sql 	//导入图片
mysql: [Warning] Using a password on the command line interface can be insecure.
[root@server mysql]# mysql -uroot -p123 zabbix < data.sql 		//导入数据
mysql: [Warning] Using a password on the command line interface can be insecure.

//编译安装zabbix
[root@server zabbix-5.4.4]# ./configure --enable-server \
> --enable-agent \
> --with-mysql \
> --with-net-snmp \
> --with-libcurl \
> --with-libxml2

[root@server zabbix-5.4.4]# make install

1.2 服务端配置

//修改服务端配置
[root@server zabbix-5.4.4]# cd /usr/local/etc/
[root@server etc]# ls
zabbix_agentd.conf  zabbix_agentd.conf.d  zabbix_server.conf  zabbix_server.conf.d
[root@server etc]# vim zabbix_server.conf
DBPassword=zabbix123!	//取消注释，设置密码

//配置开机自启
[root@server ~]# cp /usr/src/zabbix-5.4.4/misc/init.d/fedora/core/* /etc/init.d/
[root@server ~]# cat /usr/lib/systemd/system/zabbix_server.service

1.3 zabbix服务端web界面安装与配置

1.3.1 zabbix web界面安装前配置

//修改/etc/php.ini的配置并重启php-fpm
[root@server ~]# sed -ri 's/(post_max_size =).*/\1 16M/g' /etc/php.ini
[root@server ~]# sed -ri 's/(max_execution_time =).*/\1 300/g' /etc/php.ini
[root@server ~]# sed -ri 's/(max_input_time =).*/\1 300/g' /etc/php.ini
[root@server ~]# sed -i '/;date.timezone/a date.timezone = Asia/Shanghai' /etc/php.ini
[root@server ~]# systemctl restart php-fpm.service 

//创建目录，复制前端ui目录下的文件到刚才创建的目录
[root@server ~]# cd /usr/local/apache/htdocs/
[root@server htdocs]# mkdir zabbix
[root@server ~]# cd /usr/src/zabbix-5.4.4/
[root@server zabbix-5.4.4]# ls

[root@server zabbix-5.4.4]# chown -R apache: /usr/local/apache/htdocs/

//配置apache虚拟主机
[root@server ~]# tail -11 /usr/local/apache/conf/httpd.conf 

    DocumentRoot "/usr/local/apache/htdocs/zabbix"

[root@server ~]# systemctl restart httpd.service 

//设置zabbix/conf目录的权限，让zabbix有权限生成配置文件zabbix.conf.php
[root@server ~]# chmod 777 /usr/local/apache/htdocs/zabbix/conf/

1.3.2 安装zabbix web界面

恢复zabbix/conf目录的权限为755：

[root@server zabbix]# chmod 755 conf/ 
[root@server zabbix]# ll -ld conf/
