1.停止zabbix服務

service zabbix_server stop
service zabbix_agentd stop
/usr/local/zabbix/sbin/zabbix_java/shutdown.sh

2.儲存配置檔案

mv /usr/local/zabbix /usr/local/zabbix.bak
mv /usr/local/nginx/html/zabbix /usr/local/nginx/html/zabbix.bak
cp /etc/init.d/zabbix_server /etc/init.d/zabbix_server_bak
cp /etc/init.d/zabbix_agentd /etc/init.d/zabbix_agentd_bak
 

3.更新libevent
http://libevent.org/
https://github.com/libevent/libe ... 2.1.8-stable.tar.gz
tar -zxfv libevent-2.1.8-stable.tar.gz
cd libevent-2.1.8-stable
./configure
make && make install
ln -s /usr/local/lib/libevent-2.1.so.6 /usr/lib64/

4.編譯安裝zabbix3.4
tar -zxfv zabbix-3.4.7.tar.gz
cd zabbix-3.4.7
./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-mysql --with-net-snmp --with-libcurl --with-libxml2 -with-unixodbc --with-ssh2 --with-openipmi --enable-ipv6 --enable-java
./configure
make && make install

5.修改配置引數
cp /usr/local/zabbix.bak/etc/zabbix_agentd.conf /usr/local/zabbix/etc/zabbix_agentd.conf
mv /usr/local/zabbix.bak/scripts /usr/local/zabbix/
mv /usr/local/zabbix.bak/etc/zabbix_agentd.conf.d /usr/local/zabbix/etc/
mv /usr/local/zabbix.bak/sbin/zabbix_java /usr/local/zabbix/sbin/
vi /usr/local/zabbix.bak/etc/zabbix_server.conf
#3.4和3.2相比配置引數增加了，需要手動配置或者用已做好的3.4配置檔案替換，修改IP即可

mkdir -p /usr/local/zabbix/logs
chown -R zabbix:zabbix /usr/local/zabbix
mv /etc/init.d/zabbix_server_bak /etc/init.d/zabbix_server
mv /etc/init.d/zabbix_agentd_bak /etc/init.d/zabbix_agentd

6.修改網頁引數

mkdir /usr/local/nginx/html/zabbix
cp -a /root/zabbix-3.4.7/frontends/php/* /usr/local/nginx/html/zabbix
cp /usr/local/nginx/html/zabbix/conf/zabbix.conf.php.example /usr/local/nginx/html/zabbix/conf/zabbix.conf.php
vi /usr/local/nginx/html/zabbix/conf/zabbix.conf.php #3.4和3.2相比配置引數增加了，需要手動配置或者用已做好的3.4配置檔案替換，修改IP即可
chown -R zabbix.zabbix /usr/local/nginx/html/zabbix/
chmod -R 755 /usr/local/nginx/html/zabbix/

7.啟動zabbix

chkconfig --add zabbix_server
chkconfig --add zabbix_agentd
chkconfig --level 35 zabbix_agentd on
chkconfig --level 35 zabbix_server on

service snmpd restart
service mysqld restart
service httpd restart
/etc/init.d/zabbix_server start
/etc/init.d/zabbix_agentd start
/usr/local/zabbix/sbin/zabbix_java/startup.sh

8觀察日誌
