zabbix 一 ：2centos7环境部署zabbix4(服务和数据库分开)

Posted 2020-12-09 优于别人，并不高贵，真正的高贵应该是优于过去的自己！

安装步骤

1.安装mysql数据库

安装msyql5.7

wget  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
eifangwei100/java/article/details/102611519

启动数据库

systemctl start mysqld.service

systemctl status mysqld.service

查看数据库初始密码

[root@localhost opt]# grep \'password\' /var/log/mysqld.log
2020-06-08T07:30:55.369972Z 1 [Note] A temporary password is generated for root@localhost: ssiP,lSHs9gA
[root@localhost opt]# 

登录mysql数据库修改初始密码

[root@localhost opt]# mysql -uroot -p
Enter password:

注：mysql5.7默认对密码复杂度有要求

mysql> grant all privileges on *.* to \'root\'@\'%\' identified by \'Test@1234\';  
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql>

mysql> select user,host from mysql.user;

| zabbix        | %         |

| mysql.sys     | localhost |
| root          | localhost |
+---------------+-----------+
5 rows in set (0.01 sec)

mysql> 

 

 

2.安装zabbix

由于zabbix官方网站在国内下载比较慢，而且yum安装用zabbix官方源经常安装失败，我们使用阿里的镜像站。

[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ll

-rw-r--r--. 1 root root 1572 6月   8 11:57 CentOS7-Base-163.repo

-rw-r--r--. 1 root root  633 10月  7 2019 zabbix.repo
[root@localhost yum.repos.d]# 

下载安装后/etc/yum.repo目录下会生成zabbix.repo文件，修改zabbix.repo文件。

[root@localhost ~]# vim /etc/yum.repos.d/zabbix.repo

[zabbix]
name=Zabbix Official Repository - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591

[zabbix-debuginfo]
name=Zabbix Official Repository debuginfo - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/$basearch/debuginfo/
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX-A14FE591
gpgcheck=1

[zabbix-non-supported]
name=Zabbix Official Repository non-supported - $basearch
baseurl=https://mirrors.aliyun.com/zabbix/zabbix/4.4/rhel/7/x86_64/
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ZABBIX
gpgcheck=1

安装fping，以免出错

yum install -y epel-release

yum install -y iksemel fping libiksemel

 

 

 安装zabbix-server、agent和apache

yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-age

3.配置zabbix

创建初始数据库

mysql> create database zabbix character set utf8 collate utf8_bin;
Query OK, 1 row affected (0.00 sec)

mysql> grant all privileges on zabbix.* to zabbix@\'%\' identified by \'Zabbix@2019\';
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

导入初始架构和数据，系统将提示您输入新创建的密码：

 

1、首先将zabbix server的sql语句传到mysql 服务器上

[root@localhost yum.repos.d]# ls /usr/share/doc/zabbix-server-mysql-4.4.9/
AUTHORS  ChangeLog  COPYING  create.sql.gz  NEWS  README
[root@localhost yum.repos.d]# pwd
/etc/yum.repos.d
[root@localhost yum.repos.d]# scp /usr/share/doc/zabbix-server-mysql-4.4.9/create.sql.gz root@192.168.1.185:/opt/
The authenticity of host \'192.168.1.185 (192.168.1.185)\' can\'t be established.

Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added \'192.168.1.185\' (ECDSA) to the list of known hosts.

[root@localhost yum.repos.d]# 

2、导入

[root@localhost opt]# ll
总用量 1472
-rw-r--r--. 1 root root 1476578 6月   8 15:30 create.sql.gz
-rw-r--r--. 1 root root   25548 6月   8 15:16 mysql57-community-release-el7-10.noarch.rpm
drwxr-xr-x. 6 root root      56 5月  12 16:04 python3
[root@localhost opt]# zcat create.sql.gz | mysql -uzabbix -p zabbix
Enter password: 
[root@localhost opt]# 

 

为Zabbix server配置数据库，编辑配置文件 /etc/zabbix/zabbix_server.conf

[root@localhost yum.repos.d]#  grep -n \'^\'[a-Z] /etc/zabbix/zabbix_server.conf
12:ListenPort=10051
38:LogFile=/var/log/zabbix/zabbix_server.log
49:LogFileSize=0
72:PidFile=/var/run/zabbix/zabbix_server.pid
82:SocketDir=/var/run/zabbix
91:DBHost=192.168.1.185
100:DBName=zabbix
116:DBUser=zabbix
124:DBPassword=Zabbix@2019
139:DBPort=3306
356:SNMPTrapperFile=/var/log/snmptrap/snmptrap.log
473:Timeout=4
516:AlertScriptsPath=/usr/lib/zabbix/alertscripts
527:ExternalScripts=/usr/lib/zabbix/externalscripts
563:LogSlowQueries=3000
678:StatsAllowedIP=127.0.0.1
[root@localhost yum.repos.d]# 

配置php上海时区,编辑配置文件 /etc/httpd/conf.d/zabbix.conf

vim /etc/httpd/conf.d/zabbix.conf

php_value date.timezone Asia/Shanghai

启动Zabbix server和agent进程并设置开机启动

systemctl start zabbix-server zabbix-agent httpd

systemctl enable zabbix-server zabbix-agent httpd

登录并配置zabbix前端，注意配置zabbix数据库密码，其他全部下一步即可

http://192.168.1.186/zabbix

 

 

再连接数据库之前确保，zabbix server上的selinux、防火墙等关闭，否则会提示连接错误

具体信息可以查看：

【tail -f  /var/log/zabbix/zabbix_server.log  和 /var/log/messages 】

 

 

 

 

 

 

 

 

 登录zabbix页面，默认用户为Admin，密码为zabbix，用yum安装zabbix的路径是http://x.x.x.x/zabbix/
