zabbix

V. configuration zabbix_server

1, modify the configuration
 # VI / etc / ZABBIX / zabbix_server.conf

LogFile=/app/zabbix/logs/zabbix_server.log
LogFileSize=0
PidFile=/var/run/zabbix/zabbix_server.pid
SocketDir=/var/run/zabbix
DBHost=192.168.182.132
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/tmp/mysql.sock
SNMPTrapperFile=/app/zabbix/logs/snmptrap/snmptrap.log
Timeout=4
AlertScriptsPath=/app/zabbix/alertscripts
ExternalScripts=/app/zabbix/externalscripts
LogSlowQueries=3000
StatsAllowedIP=127.0.0.1

2, create the relevant directory: 
mkdir-p / App / ZABBIX / logs /the snmptrap
mkdir/ App / ZABBIX /{alertscripts, externalScripts}
chown ZABBIX: ZABBIX/ App / ZABBIX / -R & lt . 3, when the modification area: # Vim


 / etc / the httpd /conf.d/ zabbix.conf 
# Add / modify the configuration: 
php_value to the date.timezone Asia/of Shanghai . 4, start Apache 
systemctl start httpd.service . 5, starting PHP 
systemctl start PHP


-fpm.service
 . 6, starting Server ZABBIX 
systemctl ZABBIX start-server.service

access: HTTP: ip/zabbix  

Note: The first time you log in fill in mysql connection address information when needed to fill 0.0.0.0

VI. Change font

# 上传windows中的字体simkai.ttf 到/usr/share/zabbix/assets/fonts目录
# mv graphfont.ttf  graphfont.ttf.bak
ln -s /usr/share/zabbix/assets/fonts/simkai.ttf  graphfont.ttf

七.安装graphtree插件（选）

graphtree是一个图形展示插件
wget https://raw.githubusercontent.com/OneOaaS/graphtrees/master/graphtree3.0.4.patch
yum install -y patch
cp -a /usr/share/zabbix /usr/share/zabbix.bak
mv graphtree3.0.4.patch /usr/share/zabbix/
cd /usr/share/zabbix
patch  -Np0 <graphtree3.0.4.patch
chown apache:apache oneoaas -R
添加配置：vim /etc/httpd/conf.d/zabbix.conf
    Alias /oneoaas /usr/share/zabbix/oneoaas
systemctl restart httpd.service zabbix-server.service

八.zabbix proxy(192.168.182.130) 部署:

8.1、yum安装

rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
yum clean all
# 先查找zabbix-proxy,yum search zabbix-proxy
yum install zabbix-proxy-mysql.x86_64 zabbix-agent.x86_64
# 如果出现如下错误

Error: Package: zabbix-proxy-mysql-4.4.3-1.el7.x86_64 (zabbix)
           Requires: fping
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

# 解决方案：

      # 根据错误提示，需要安装fping命令这个依赖，在进行yum安装之后显示该安装包不存在，因此进行推测应该是epel源配置出现问题，因此在阿里源中配置epel源

curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all
yum makecache
# 再执行
yum install zabbix-proxy-mysql.x86_64 zabbix-agent.x86_64

# 创建zabbix库：
create database zabbix_proxy character set utf8 collate utf8_bin;
# 授权：
grant all privileges on zabbix_proxy.* to zabbix@'%' identified by 'zabbix';
# 刷新权限
flush privileges;

# 部署mysql 步骤和在zabbix server中部署一样，区别在导入数据时候不一样：
# zcat /usr/share/doc/zabbix-proxy-mysql*/schema.sql.gz | mysql -uroot -p zabbix_proxy

# 修改zabbix-proxy配置：vim /etc/zabbix/zabbix_proxy.conf

Server=192.168.182.132            # 真正的服务端(zabbix server)
ServerPort=10051                  # 根据个人需要修改，一般可以不改，默认端口是10051，要实现转发的话使用这个选项(zabbix server)
ListenPort=10051                  # zabbix-proxy服务监听的端口，默认就好
Hostname=Zabbix proxy             # proxy的hostname，在web端网页配置时需要用到
DBHost=192.168.182.130            # 数据库，使用本地，也可以使用ip，我喜欢使用localhost，因为我授权就是本地，也因为配置ip失败踩过坑
DBName=zabbix_proxy               # 数据库名称，创建zabbix-proxy的mysql的数据库名称
DBUser=zabbix                     # 用户
DBPassword=zabbix                 # 密码
DBPort=3306                       # 当DBHost填写localhost时，默认是使用socket通信的，这里配置一下也无碍
#HeartbeatFrequency=60            # 心跳线（具体作用网了，看配置文件吧，这个默认就是60）
ConfigFrequency=600               # 这个好像是同步配置文件的时间
DataSenderFrequency=1             # 这个是proxy端向server端发送数据的时间，单位是秒，几乎等于实时同步

# 启动zabbix-proxy 
systemctl start zabbix-proxy.service

8.2 、源码安装

yum -y install curl-devel libevent-devel   libevent curl  libxml2-devel libxml2  pcre pcre-devel
yum install mysql-devel  -y
yum install -y net-snmp-devel

# 编译安装zabbix proxy：
wget https://nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/4.4.0/zabbix-4.4.0.tar.gz
tar -xzvf zabbix-4.4.0.tar.gz
cd zabbix-4.4.0

# proxy：
 ./configure --prefix=/app/zabbix_proxy_4.4   --enable-proxy  --with-mysql   --with-libcurl --with-libxml2  --enable-ipv6 --with-net-snmp --with-openssl
ln -s /app/mysql/lib/libmysqlclient.so.20 /usr/lib64/libmysqlclient.so.20
# 启动:
/app/zabbix_proxy_4.4/sbin/zabbix_proxy -c /app/zabbix_proxy_4.4/etc/zabbix_proxy.conf

8.2 、web端配置代理

8.2.1、web配置zabbix代理

 

 

 

如果出现如下图，则zabbix server不能与zabbix proxy正常通信

 

 

 正常通信如图：

九.zabbix客户端安装

9.1、yum安装

# 添加yum源
rpm -Uvh https://repo.zabbix.com/zabbix/4.4/rhel/7/x86_64/zabbix-release-4.4-1.el7.noarch.rpm
# 安装
yum install zabbix-agent
# 启动
service zabbix-agent start

9.2、源码安装

yum -y install curl-devel libevent-devel   libevent curl  libxml2-devel libxml2  pcre pcre-devel
yum install mysql-devel  -y
yum install -y net-snmp-devel

# 编译安装zabbix客户端：
wget https://nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/4.4.0/zabbix-4.4.0.tar.gz
tar -xzvf zabbix-4.4.0.tar.gz
cd zabbix-4.4.0

# agent：
 ./configure --prefix=/app/zabbix_agent_4.4   --enable-agent  --enable-ipv6 --with-net-snmp --with-openssl

# 启动：
/app/zabbix_agent_4.4/sbin/zabbix_agentd -c /app/zabbix_agent_4.4/etc/zabbix_agentd.conf

9.3、修改配置

Server=[zabbix server ip]
ServerActive=[zabbix server ip]
Hostname=[ Hostname of client system ]
# 例：
Server=192.168.182.132
ServerActive=192.168.182.132
Hostname=192.168.182.128

9.4、安装zabbix-get，并测试agent端是否server端连通

# 安装
yum install -y zabbix-get
# 在服务端测试（192.168.182.132），-s --host:agent端ip；-p,--port:端口；-k,--key：监控项key
zabbix_get -s 192.168.182.130 -p 10050 -k system.hostname

十. 常用命令

zabbix server与zabbix proxy的配置的同步是有延时的，如果需要立即同步可以手动执行命令:
zabbix_proxy -c /etc/zabbix/zabbix_proxy.conf  -R config_cache_reload
