Linux下把Zabbix2.2升级到Zabbix3.0.2过程。
备份备份。。
[root@Server ~]# cp -a /usr/share/zabbix /tmp/zabbix.bak
备份数据库，也可以使用mysqldump命令等等。
[root@Server ~]# cp /var/lib/mysql /tmp/mysql.bak
备份zabbix_server.conf文件
[root@Server ~]# cp /etc/zabbix/zabbix_server.conf /tmp/zabbix_server.conf.bak
2、Zabbix 3.x对PHP的要求最低为5.4，而CentOS6默认为5.3.3，完全不满足要求，故需要利用第三方源，将PHP升级到5.4以上，注意，不支持PHP7
3、安装php第三方源，并安装相应php版本
[root@Server ~]# rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm
Retrieving http://mirror.webtatic.com/yum/el6/latest.rpm
warning: /var/tmp/rpm-tmp.E9X3kG: Header V4 DSA/SHA1 Signature, key ID cf4c4ff9: NOKEY
Preparing... ########################################### [100%]
1:webtatic-release ########################################### [100%]
这里选择php5.5版本安装
[root@Server ~]# yum install php55w.x86_64 php55w-cli.x86_64 php55w-common.x86_64 php55w-gd.x86_64 php55w-ldap.x86_64 php55w-mbstring.x86_64 php55w-mcrypt.x86_64 php55w-mysql.x86_64 php55w-pdo.x86_64 -y
查看安装后的php版本
[root@Server ~]# php -v

4、zabbix3.x版本需要curl版，curl >= 7.20 (如需支持SMTP认证)
[root@Server ~]# rpm -ivh http://mirror.city-fan.org/ftp/contrib/yum-repo/city-fan.org-release-1-13.rhel6.noarch.rpm
Retrieving http://mirror.city-fan.org/ftp/contrib/yum-repo/city-fan.org-release-1-13.rhel6.noarch.rpm
warning: /var/tmp/rpm-tmp.Y3iyPw: Header V3 DSA/SHA1 Signature, key ID b56a8bac: NOKEY
Preparing... ########################################### [100%]
1:city-fan.org-release ########################################### [100%]
[root@Server ~]# yum upgrade libcurl -y
卸载第三方源，卸载不卸载自己看着办，随意
[root@Server ~]# rpm -e city-fan.org-release
官方没有提供centos6 zabbix3.0 server，我是git clone itnihao的github上。。。
[root@Server ~]# git clone https://github.com/zabbixcn/zabbix3.0-rpm.git

package webtatic-release-6-6.noarch is already installed
5、安装zabbix web以及mysql等
[root@Server RPMS]# pwd
/root/zabbix3.0-rpm/RPMS
[root@Server RPMS]# yum install zabbix-web-mysql-3.0.0-1.el6.noarch.rpm zabbix-web-3.0.0-1.el6.noarch.rpm -y
如果yum安装过程中出现......Error Summary问题，把原来zabbix卸载即可
[root@Server RPMS]# yum remove zabbix22 -y
[root@Server RPMS]# yum install zabbix-server-mysql-3.0.0-1.el6.x86_64.rpm -y
6、启动服务
[root@Server RPMS]# /etc/init.d/httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ]
[root@Server RPMS]# /etc/init.d/mysqld start
Starting mysqld: [ OK ]
启动zabbix-server出现cannot open "/var/log/zabbixsrv/zabbix_server.log": [13] Permission denied
[root@Server web]# /etc/init.d/zabbix-server restart
Shutting down Zabbix server: [FAILED]
Starting Zabbix server: [ OK ]
[root@Server web]# zabbix_server [2285]: cannot open "/var/log/zabbixsrv/zabbix_server.log": [13] Permission denied
解决：
12345 [root@Server zabbixsrv]# touch /var/log/zabbixsrv/zabbix_server.log
[root@Server zabbixsrv]# chown zabbix zabbix_server.log
[root@Server zabbixsrv]# /etc/init.d/zabbix-server restart
Shutting down Zabbix server: [FAILED]
Starting Zabbix server: [ OK ]
出现pid问题
[root@Server zabbixsrv]# tail -f zabbix_server.log
zabbix_server [2368]: cannot create PID file [/var/run/zabbixsrv/zabbix_server.pid]: [2] No such file or directory
创建相应目录以及相应的权限即可，最后重启服务
[root@Server zabbixsrv]# mkdir /var/run/zabbixsrv/
[root@Server zabbixsrv]# chown zabbix /var/run/zabbixsrv/ -R
[root@Server zabbixsrv]# /etc/init.d/zabbix-server restart
Shutting down Zabbix server: [FAILED]
Starting Zabbix server: [ OK ]
7、替换date.timezone改成Shanghai即可，操作如下
[root@Server ~]# cd /etc/httpd/conf.d/
[root@Server conf.d]# ls
php.conf README welcome.conf zabbix.conf
[root@Server conf.d]# cp zabbix.conf zabbix.conf.bak
[root@Server conf.d]# sed -i "s@# php_value date.timezone Europe/Riga@php_value date.timezone Asia/Shanghai@g" /etc/httpd/conf.d/zabbix.conf
重启httpd服务即可
[root@Server conf.d]# /etc/init.d/httpd restart
Stopping httpd: [FAILED]
Starting httpd: [ OK ]
8、安装agent3.0版本
[root@Server RPMS]# pwd
/root/zabbix3.0-rpm/RPMS
[root@Server RPMS]# ls
zabbix-agent-3.0.0-1.el6.x86_64.rpm zabbix-proxy-sqlite3-3.0.0-1.el6.x86_64.rpm zabbix-web-japanese-3.0.0-1.el6.noarch.rpm
zabbix-get-3.0.0-1.el6.x86_64.rpm zabbix-sender-3.0.0-1.el6.x86_64.rpm zabbix-web-mysql-3.0.0-1.el6.noarch.rpm
zabbix-java-gateway-3.0.0-1.el6.x86_64.rpm zabbix-server-mysql-3.0.0-1.el6.x86_64.rpm zabbix-web-pgsql-3.0.0-1.el6.noarch.rpm
zabbix-proxy-mysql-3.0.0-1.el6.x86_64.rpm zabbix-server-pgsql-3.0.0-1.el6.x86_64.rpm
zabbix-proxy-pgsql-3.0.0-1.el6.x86_64.rpm zabbix-web-3.0.0-1.el6.noarch.rpm
安装zabbix-agent3.0版本即可。也可以yum install *.rpm安装所有的，根据自己的情况去安装即可
[root@Server RPMS]# yum install zabbix-agent-3.0.0-1.el6.x86_64.rpm
查看zabbix-agent安装后的版本
[root@Server zabbix]# zabbix_agentd -V
zabbix_agentd (daemon) (Zabbix) 3.0.0
Revision 58460 15 February 2016, compilation time: Feb 17 2016 09:55:34
修改zabbix_agentd.conf文件连接zabbix-server服务器ip地址即可，重启服务
[root@Server zabbix]# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent: [FAILED]
Starting Zabbix agent: [ OK ]
