一、关闭SELinux
查询是否开启了SELinux
getenforce
SELinux一共有3种状态，分别是**Enforcing，Permissive**和**Disabled**状态。第一种是默认状态，表示强制启用，第二种是宽容的意思，即大部分规则都放行。第三种是禁用，即不设置任何规则
setenforce 0 #把SELinux关闭，此操作为临时关闭，重启后失效
vim /etc/selnux/conf #修改为disabled，此操作为永久关闭，重启后生效。
#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 #disabled为关闭#SELINUXTYPE= can take one of three two values:#targeted - Targeted processes are protected,#minimum - Modification of targeted policy. Only selected processes are protected. #mls - Multi Level Security protection.SELINUXTYPE=targeted
二、关闭或防火墙或开放必需端口
#关闭防火墙，并且禁用开机自启。 systemctl stop firewalld.service #停止firewall systemctl disable firewalld.service #禁止firewall开机启动 或者 开放防火墙相应端口 firewall-cmd --zone=public --add-port=80/tcp --permanent #–permanent #永久生效，没有此参数重启后失效
firewall-cmd --list-ports #查看已经开启的端口 firewall-cmd --reload #重新载入 firewall-cmd --zone= public --query-port=80/tcp #查看 firewall-cmd --zone= public --remove-port=80/tcp --permanent #删除
三、安装Zabbix的Yum源，以及MySQL的源。
http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/ #在这个页面下，找到release的rpm包，并且安装到系统上
rpm -ivh http://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm rpm -ivh http://repo.mysql.com/yum/mysql-5.6-community/el/6/x86_64/mysql-community-release-el6-5.noarch.rpm
四、安装Zabbix和MySQL
yum install -y zabbix-server-mysql zabbix-web-mysql mysql-community-server zabbix-agent systemctl start mysqld #启动MySQL数据库 mysql_secure_installation #初始化数据库信息
五、创建zabbix数据库，创建zabbix账号
mysql -uroot -p ... 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'@'localhost' identified by 'zabbix'; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.01 sec)
六、导入默认的Zabbix数据库信息
zcat /usr/share/doc/zabbix-server-mysql-3.0.18/create.sql.gz | mysql zabbix -uzabbix -pzabbix
七、修改Zabbix_server.conf的配置文件，将以下行内容修改正确，DBPassword是刚才创建数据库的密码。
[root@linux-node2 ~]# grep ^DB /etc/zabbix/zabbix_server.conf DBHost=localhost DBName=zabbix DBUser=zabbix DBPassword=zabbix
八、修改配置文件/etc/httpd/conf.d/zabbix.conf，时区改成Asia/Shanghai
php_value max_execution_time 300 php_value memory_limit 128M php_value post_max_size 16M php_value upload_max_filesize 2M php_value max_input_time 300 php_value always_populate_raw_post_data -1 php_value date.timezone Asia/Shanghai
九、启动各项服务并设置为开机启动
systemctl start zabbix-server.service systemctl start mysqld.service systemctl start httpd.service systemctl start zabbix-agent.service systemctl enable zabbix-server systemctl enable mysqld systemctl enable httpd systemctl enable zabbix-agent
Zabbix-server的默认账号Admin，密码zabbix
移除或改名web目录下面的setup.php文件
mv setup.php setup.php.bak
登陆成功后马上更改Admin的密码
