01zabbixcentos7官方教程安装zabbix4.020201130更新含安装mysql5.7

先给上zabbix4.0&＃xff0c;centos的rpo链接&＃xff1a;Zabbix Official Repository

,
A。安装Zabbix存储库文件  B 。安装Zabbix服务器&＃xff0c;前端&＃xff0c;代理

rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/7/x86_64/zabbix-release-4.0-2.el7.noarch.rpm
yum clean all
yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get

# redhat 如果报错参考链接&＃xff1a;zabbix-server-mysql [Errno 256] No more mirrors to try_shaoqiu.wu的博客-CSDN博客  

修改yum  zabbix.repo文件如下&＃xff1a;

C。安装mysql数据库 参考链接Centos7 安装MySQL 5.7 - 张顺海 - 博客园

#  rpm离线安装mysql  Centos 离线安装mysql5.7.32_疏笃-CSDN博客

# 下载并安装MySQL官方的 Yum Repository   有点慢  感觉回头还是考虑找个国内源

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server # 这步可能会花些时间&＃xff0c;安装完成后就会覆盖掉之前的mariadb。

 # 报错解决&＃xff1a;

rpm gpg key mysql_记录无法安装mysql-Invalid GPG Key from file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql的解决办法...

修改gpgcheck&＃61;0即可

sed -i &＃39;s/gpgcheck&＃61;1/gpgcheck&＃61;0/g&＃39; /etc/yum.repos.d/mysql-community.repo
sed -i &＃39;s/gpgcheck&＃61;1/gpgcheck&＃61;0/g&＃39; /etc/yum.repos.d/mysql-community-source.repo
yum -y install mysql-community-server # 这步可能会花些时间&＃xff0c;安装完成后就会覆盖掉之前的mariadb。

rpm gpg key mysql_记录无法安装mysql-Invalid GPG Key from file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql的解决办法..._邝彬的博客-CSDN博客

# 首先启动MySQL

systemctl start mysqld.service

# 查看初始密码

grep "password" /var/log/mysqld.log

# 进入mysql
 mysql -uroot -p
输入password

# 需要先修改root密码

法一&＃xff1a;

alter user &＃39;root&＃39;&＃64;&＃39;localhost&＃39; identified by &＃39;cy7m0ypu8CpLFperzI45&＃39;;

法二&＃xff1a;

set password for &＃39;root&＃39;&＃64;&＃39;localhost&＃39;&＃61;password(&＃39;cy7m0ypu8CpLFperzI45&＃39;);

法三&＃xff1a;

update mysql.user set authentication_string&＃61;password(&＃39;cy7m0ypu8CpLFperzI45&＃39;) where user&＃61;&＃39;root&＃39; and Host &＃61; &＃39;localhost&＃39;;

#记得最后要刷新权限
flush privileges;

D 如果根分区比较小 建议修改数据库存放位置至 /home下&＃xff1a;

参考&＃xff1a;  Centos 更改MySQL5.7数据库目录位置_酷玩时刻-By Javen-CSDN博客_centos mysql 目录   

有坑参考&＃xff1a;centos7 mysql5.7.32 修改存储位置_yuezhilangniao的博客-CSDN博客_centos7修改mysql存储位置

# 创建zabbix数据库和 zabbix用户访问zabbix库权限

create database zabbix character set utf8 collate utf8_bin;
grant all privileges on zabbix.* to zabbix&＃64;localhost identified by &＃39;password&＃39;;
quit;

# 系统会提示你输入上面设置的密码“password”
 

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

D。为Zabbix服务器配置 数据库配置

#vim /etc/zabbix/zabbix_server.conf   添加 DBPassword&＃61;password 

 或

echo  "DBPassword&＃61;password"   /etc/zabbix/zabbix_server.conf 

或  

sed -e "/126/a DBPassword&＃61;Password" -i /etc/zabbix/zabbix_server.conf

即 为Zabbix前端配置PHP
编辑文件/etc/httpd/conf.d/zabbix.conf&＃xff0c;取消注释并为您设置正确的时区。
# php_value date.timezone Asia/Shanghai

E。启动Zabbix服务器和代理进程
启动Zabbix服务器和代理程序进程并使其在系统引导时启动&＃xff1a;

systemctl restart zabbix-server zabbix-agent httpd
systemctl enable zabbix-server zabbix-agent httpd

现在您的Zabbix服务器已启动并运行&＃xff01;

打开Zabbix前端
关闭防火墙
#vim /etc/selinux/config
   
#setenforce 0
   
#systemctl stop firewalld
  
连接到新安装的Zabbix前端&＃xff1a;http&＃xff1a;// server_ip_or_name / zabbix

需要几步设置数据库和server的基本信息 这里截图最后两步

# 设置完成后登陆  默认初始账号Admin  密码 zabbix

# 记录一次数据库报错  未解决 

# tail -f /var/log/mysqld
Got an error reading communication packets
