Centos7.9安装Zabbix4.2

缥帙各舒散，前后互相逾。这篇文章主要讲述Centos7.9安装Zabbix4.2相关的知识，希望能为你提供帮助。
Centos7.9安装Zabbix4.2查看系统信息：

[root@localhost opt]# uname -r
3.10.0-1160.el7.x86_64
[root@localhost opt]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

关闭系统防火墙

[root@shell ~]# systemctl stopfirewalld
[root@shell ~]# systemctl disablefirewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

查看selinux是否关闭

[root@shell ~]# grep -Ev "SELINUXTYPE=|^#" /etc/selinux/config
SELINUX=disabled

一、下载安装所需文件
1.1下载zabbix库文件

[root@shell ~]# rpm -Uvh https://repo.zabbix.com/zabbix/4.2/rhel/7/x86_64/zabbix-release-4.2-1.el7.noarch.rpm

1.2下载阿里镜像包

[root@shell ~]# yum -y install wget

[root@shell ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

1.3安装fedora存储库

[root@shell ~]# yum install -y epel-release

二、安装Zabbix-server
（自动安装依赖的httpd和php）

[root@shell ~]# yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

Installed:
zabbix-agent.x86_64 0:4.2.8-1.el7zabbix-server-mysql.x86_64 0:4.2.8-1.el7zabbix-web-mysql.noarch 0:4.2.8-1.el7

Complete!

三、安装mysql数据库
3.1安装依赖包

[root@shell ~]# yum -y install gcc gcc-c++ ncurses bison libgcrypt perl cmake ncurses-devel

3.2下载mysql5.7整合包（可以其他方式安装mysql数据库）

[root@shell ~]# wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.24-1.el7.x86_64.rpm-bundle.tar

3.3解压整合包，再安装依赖包

[root@shell ~]# tar xvf mysql-5.7.24-1.el7.x86_64.rpm-bundle.tar
mysql-community-common-5.7.24-1.el7.x86_64.rpm
mysql-community-minimal-debuginfo-5.7.24-1.el7.x86_64.rpm
mysql-community-embedded-compat-5.7.24-1.el7.x86_64.rpm
mysql-community-embedded-devel-5.7.24-1.el7.x86_64.rpm
mysql-community-embedded-5.7.24-1.el7.x86_64.rpm
mysql-community-libs-5.7.24-1.el7.x86_64.rpm
mysql-community-devel-5.7.24-1.el7.x86_64.rpm
mysql-community-server-5.7.24-1.el7.x86_64.rpm
mysql-community-libs-compat-5.7.24-1.el7.x86_64.rpm
mysql-community-client-5.7.24-1.el7.x86_64.rpm
mysql-community-server-minimal-5.7.24-1.el7.x86_64.rpm
mysql-community-test-5.7.24-1.el7.x86_64.rpm
[root@shell ~]# yum -y install mysql-community-{client,common,libs}-*

3.4安装mysql服务

[root@shell ~]# rpm -ivh mysql-community-server-5.7.24-1.el7.x86_64.rpm
warning: mysql-community-server-5.7.24-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:
net-tools is needed by mysql-community-server-5.7.24-1.el7.x86_64

报错，无法安装。这是由于yum安装了旧版本的GPG keys造成的，因为从 RPM 版本 4.1 开始，在安装或升级软件包时会检查软件包的签名。如果签名校验失败，你就会看到如下所示的错误消息：

解决方法：在安装命令后面加上 --force --nodeps，进行强制安装。

[root@shell ~]# rpm -ivh mysql-community-server-5.7.24-1.el7.x86_64.rpm--force --nodeps
warning: mysql-community-server-5.7.24-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

四、修改Zabbix-server配置

[root@shell ~]# vim /etc/zabbix/zabbix_server.conf

ListenPort=10051
DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=eqwOP@OF2kzR34
#DBSocket路径根据mysql的配置文件/etc/my.cnf设置
DBSocket=/var/run/mysqld/mysql.socket
DBPort=3306

4.1修改zabbix时区

[root@shell ~]# sed -i "s/# php_value date.timezone Europe\\/Riga/php_value date.timezone Asia\\/Shanghai/" /etc/httpd/conf.d/zabbix.conf
[root@shell ~]# grep date /etc/httpd/conf.d/zabbix.conf

[root@shell ~]#

4.4修改访问Zabbix默认URL

[root@shell ~]# sed -i \'s/DocumentRoot "\\/var\\/www\\/html"/DocumentRoot "\\/usr\\/share\\/zabbix"/\' /etc/httpd/conf/httpd.conf
[root@shell ~]# cat /etc/httpd/conf/httpd.conf |grep "DocumentRoot "
DocumentRoot "/usr/share/zabbix"
[root@shell ~]#

4.5修改中文显示乱码问题在win10上的C:\\Windows\\Fonts找一个字体拷贝到服务器

[root@shell ~]# yum -y install lrzsz
[root@shell ~]# rz
