zabbix2升级zabbix3

1.停服zabbix2，停服数据库
/etc/init.d/zabbix_server stop
/etc/init.d/mysqld stop

2.物理备份数据库
cd /var/lib/mysql/
tar -zcvf /tmp/data_zabbix2_20170306.tar.gz *

3.安装依赖包
yum -y install net-snmp-devel libxml2-devel libcurl-devel php-gd mysql-devel gcc net-snmp-devel curl-devel perl-DBI php-mysql php-bcmath php-mbstring php-xml

4.下载zabbix3源码包
wget https://jaist.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.0.7/zabbix-3.0.7.tar.gz

5.解压并安装
tar -xf zabbix-3.0.7.tar.gz
cd zabbix-3.0.7
mkdir -p /usr/local/zabbix/
./configure --prefix=/usr/local/zabbix/ --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl --with-libxml2

6.替换zabbix3启动脚本以及配置文件
cd zabbix-3.0.7
cp misc/init.d/tru64/zabbix_agentd /etc/init.d/zabbix3_agentd
cp misc/init.d/tru64/zabbix_server /etc/init.d/zabbix3_server
sed -i 's/\(DAEMON=\/usr\/local\/\)\(sbin\/zabbix_server\)/\1zabbix\/\2/g' /etc/init.d/zabbix3_server

7.拷贝前端文件
\cp /root/zabbix-3.0.7/frontends/php/* /var/www/html/zabbix3/ -rp

8.配置前端文件
http://IP/zabbix3/setup.php
或者
cp /var/www/html/zabbix/conf/zabbix.conf.php /var/www/html/zabbix3/conf/zabbix.conf.php

9.启动mysql

10.启动zabbix3
/etc/init.d/zabbix3_server start
/etc/init.d/zabbix3_agentd start

11.查看zabbix_server日志中数据库的自动升级进度
