zabbix4.0安装步骤

1.配置初始环境
增大文件描述符

	cat >> /etc/security/limits.conf <<EOF
	root soft nofile 65535
	root hard nofile 65535
	* soft nproc 65535
	* hard nproc 65535
	* soft nofile 65535
	* hard nofile 65535
	EOF
	echo "ulimit -SH 65535" >> /etc/rc.local
	ulimit -SH 65535

2.配置yum环境

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
#这边要进行一个换源，要不然会被墙（最近才被墙）
复制zabbix.repo 到其他服务器

3.安装zabbix-server #只在服务端安装

yum install zabbix-server-mysql zabbix-web-mysql zabbix-agent httpd yum install zabbix-get -y   #客户端只安装agent
yum install zabbix-agent -y

4.安装mysql数据库

yum install mariadb-server -y
systemctl start mariadb
systemctl enable mariadb

5.导入表结构

mysql_secure_installation
mysql -e "create database zabbix character set utf8 collate utf8_bin;"
mysql -e "grant all privileges on zabbix.* to zabbix@localhost identified by '123456';"
zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql  zabbix

6，修改配置文件

vi /etc/zabbix/zabbix_server.conf 
DBHost=localhost 
DBName=zabbix
DBUser=zabbix
DBPassword=1qaz@WSX


vi /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai

7.启动

systemctl start zabbix-server
systemctl enable zabbix-server
systemctl start httpd
systemctl enable httpd

8.进入zabbix界面
配置数据库用户密码

账号 Admin 密码 zabbix

9.导入模板

10.修改模板

cp userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/
vim ss_get_mysql_stats.php #修改账号密码
vim get_mysql_stats_wrapper.sh #修改账号密码  主从同步的

11.安装测试用数据库（agent）
