当然也可以使用源码安装，在编译时候指定agent（但是不建议使用源码安装时候新建zabbix账户，因为考虑系统的安全性。建议建立无法登陆的账号）
./configure --prefix=/usr/local/zabbix-3.0.3/ --enable-agent

2. 配置zabbix-agent配置文件

vi /etc/zabbix/zabbix_agentd.conf
修改如下参数：
Server=server端ip地址                      #用于被动模式，数据获取
ServerActive=server端ip地址                #用于主动模式，数据提交
Hostname=mysql5.6  #该值跟zabbixweb上配置的主机名称要一致(配置-》主机-》主机名称)
Include=/etc/zabbix/zabbix_agentd.d/userparameter_percona_mysql.conf #此配置用于设置mysql插件监控 如果没有设置可以保持默认
ListenPort=10050 #默认是10050端口，这行是注释掉的可以更其他监控端口

3. 启动和防火墙设置

[root@localhost tmp]# service zabbix-agent start
Starting Zabbix agent:                                     [确定]
[root@localhost tmp]# ps -ef|grep zabbix
zabbix    1671     1  0 14:34 ?        00:00:00 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf
zabbix    1672  1671  0 14:34 ?        00:00:00 /usr/sbin/zabbix_agentd: collector [idle 1 sec]          
zabbix    1673  1671  0 14:34 ?        00:00:00 /usr/sbin/zabbix_agentd: listener #1 [waiting for connection]
zabbix    1674  1671  0 14:34 ?        00:00:00 /usr/sbin/zabbix_agentd: listener #2 [waiting for connection]
zabbix    1675  1671  0 14:34 ?        00:00:00 /usr/sbin/zabbix_agentd: listener #3 [waiting for connection]
zabbix    1676  1671  0 14:34 ?        00:00:00 /usr/sbin/zabbix_agentd: active checks #1 [idle 1 sec]

在启动时候会遇到两个问题，启动时候，发现没有zabbix进程，原因没有关闭selinux服务，临时关闭有时候也无效，建议修改/etc/selinux/config，修改后重启主机。再次启动就可以了

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled #此项改为disable  
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

在一个问题是启动了，但是在web端配置时候发现还是连不上需要修改防火墙配置

vi /etc//etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
#ZABBIX PORT 
-A INPUT -m state --state NEW -m tcp -p tcp --dport 10041 -j ACCEPT (根据你的配置设置端口号)
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
service iptables restart

再就是主机启动以后zabbix的服务自动启动，可以如下设置：其他想开机启动也可以像如下设置

echo "service zabbix-agent start">>/etc/rc.local

4.web端设置

创建主机
