夜莺监控钉钉告警模板

1.关闭防火墙、关闭SELINUX

systemctl stop firewalld.service

setenforce 0

配置mysql源

#下载MySQL源

wget https://dev.mysql.com/get/mysql80-community-release-el7-5.noarch.rpm

#安装依赖环境

yum -y install gcc-c++ mysql-devel net-snmp-devel libevent-devel

#配置MySQL源

yum -y install mysql80-community-release-el7-5.noarch.rpm

下载MySQL和zabbix

#下载zabbix

wget https://cdn.zabbix.com/zabbix/sources/stable/6.0/zabbix-6.0.1.tar.gz

#下载MySQL

wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar

解压并安装下载好的MySQL安装包

#创建MySQL目录

mkdir /usr/local/mysql

#解压MySQL安装包

tar xf mysql-8.0.28-1.el7.x86_64.rpm-bundle.tar -C /usr/local/mysql

#移动到mysql目录

cd /usr/local/mysql/

#RPM方式安装MySQL

rpm -ivh mysql-community-common-8.0.28-1.el7.x86_64.rpm --force --nodeps

rpm -ivh mysql-community-libs-8.0.28-1.el7.x86_64.rpm --force --nodeps

rpm -ivh mysql-community-libs-compat-8.0.28-1.el7.x86_64.rpm --force --nodeps

rpm -ivh mysql-community-client-8.0.28-1.el7.x86_64.rpm --force --nodeps

rpm -ivh mysql-community-server-8.0.28-1.el7.x86_64.rpm --force --nodeps

检查MySQL的个RPM包是否被安装

rpm -qa |grep mysql

#显示如下安装包

mysql-community-server-8.0.28-1.el7.x86_64

mysql-community-libs-compat-8.0.28-1.el7.x86_64

mysql-community-client-plugins-8.0.29-1.el7.x86_64

mysql-community-common-8.0.29-1.el7.x86_64

mysql-community-devel-8.0.29-1.el7.x86_64

mysql-community-common-8.0.28-1.el7.x86_64

mysql-community-libs-8.0.29-1.el7.x86_64

mysql80-community-release-el7-5.noarch

mysql-community-libs-compat-8.0.29-1.el7.x86_64

mysql-community-client-8.0.28-1.el7.x86_64

mysql-community-libs-8.0.28-1.el7.x86_64

启动MySQL并加入开机自启

#启动MySQL

systemctl start mysqld

#MySQL加入开启自启

systemctl enable mysqld

检查MySQL服务是否启动

systemctl status mysqld.service

启动mysql后会初始化 查找mysql密码

cat /var/log/mysqld.log | grep password

2022-06-23T16:15:31.370137Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: Dfo5Dm-!fVZG

#密码为：Dfo5Dm-!fVZG

修改MySQL的root密码

#由于MySQL8.0 有密码验证组件，若希望设置简单的密码，需要修改服务验证条件

# 密码检查等级，0/LOW、1/MEDIUM、2/STRONG

set global validate_password.policy=0;

# 密码的最短长度

set global validate_password.length=6;

# 密码至少要包含的小写字母个数和大写字母个数

set global validate_password.mixed_case_count=0;

# 设置密码

mysql -uroot -p

ALTER USER 'root'@'localhost' IDENTIFIED BY 'Resset@)@@2022';

创建zabbix库

#创建zabbix库

create database zabbix character set utf8 collate utf8_bin;

#创建zabbix用户

create user zabbix@localhost identified by 'Resset@)@@123';

#授权

grant all privileges on zabbix.* to zabbix@localhost;

安装zabbix 6.1

#创建zabbix目录

mkdir /usr/local/zabbix

#解压

tar -zxvf zabbix-6.0.1.tar.gz -C /usr/local/zabbix/

创建用户账户

#创建zabbix组

groupadd zabbix

#创建zabbix用户

useradd -g zabbix -M -s /sbin/nologin zabbix

在zabbix目录中编译安装

#移动到zabbix目录

cd /usr/local/zabbix/zabbix-6.0.1/

#编译

./configure --prefix=/usr/local/zabbix/ --enable-server --enable-agent --with-net-snmp --with-mysql

make install

安装PHP

由于CentOS7自带PHP版本为5.6，所以需要安装额外的库，也是remi的库

yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm  

yum -y install yum-utils

yum-config-manager --disable 'remi-php*'

yum-config-manager --enable   remi-php74

yum -y install php php-bcmath php-gd php-xml  php-mbstring php-mysqlnd php-ldap

yum -y install curl-devl libxml2 libxml2-devel

需要修改php参数（网页预配置必要条件）

vim /etc/php.ini

修改post_max_size为16M

修改max_execution_time为300

修改max_input_time为300

配置httpd

移动前端文件至web服务的根目录并授权

cp -r /usr/local/zabbix/zabbix-6.0.1/ui/* /var/www/html/

chown apache:apache /var/www/html -R

导入数据库架构及数据

mysql -uzabbix -p zabbix < /usr/local/zabbix/zabbix-6.0.1/database/mysql/schema.sql

mysql -uzabbix -p zabbix < /usr/local/zabbix/zabbix-6.0.1/database/mysql/images.sql

mysql -uzabbix -p zabbix < /usr/local/zabbix/zabbix-6.0.1/database/mysql/data.sql

修改配置zabbixserver文件数据库密码

vim /usr/local/zabbix/etc/zabbix_server.conf

# DBPassword= 修改为MySQL的zabbix用户密码

DBPassword=Resset@)@@123

开启httpd  zabbix

service httpd start

systemctl enable httpd.service

cd /usr/local/zabbix/sbin/

./zabbix_server
