安装zabbix需要php的两个模块php-bcmath和php-mbstring

 
1.操作系统版本

1. [root@aws zabbix]# cat /etc/redhat-release 
2. Red Hat Enterprise Linux Server release 7.4 (Maipo)

2.在安装zabbix的时候报错（红色是执行的语句），如下：

1. yum install zabbix-server-mysql zabbix-web-mysql
3. --> Finished Dependency Resolution
4. Error: Package: zabbix-web-3.4.7-1.el7.noarch (zabbix)
5.            Requires: php-bcmath
6. Error: Package: zabbix-web-3.4.7-1.el7.noarch (zabbix)
7.            Requires: php-mbstring
8.  You could try using --skip-broken to work around the problem
9.  You could try running: rpm -Va --nofiles --nodigest

3.这两个模块的yum源比较少，在网上发现163的yum源包含它们，那么就需要替换yum源，步骤如下：

a.进入yum源目录

1. cd /etc/yum.repos.d

b.执行

1. [root@aws yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

c.因为我目前是redhat7，所以要编辑这个文件，黑色加粗斜体是我改的，屏蔽3行，增加3行

1. # CentOS-Base.repo
2. #
3. # The mirror system uses the connecting IP address of the client and the
4. # update status of each mirror to pick mirrors that are updated to and
5. # geographically close to the client. You should use this for CentOS updates
6. # unless you are manually picking other mirrors.
7. #
8. # If the mirrorlist= does not work for you, as a fall back you can try the
9. # remarked out baseurl= line instead.
10. #

4.清除和创建yum缓存

1. yum clean all
2. yum makecache

5.再次执行安装zabbix

1. yum install zabbix-server-mysql zabbix-web-mysql
