1.停止zabbix服务
service zabbix_server stop
service zabbix_agentd stop
/usr/local/zabbix/sbin/zabbix_java/shutdown.sh
2.保存配置文件
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.编译安装zabbix4.2
tar -xf zabbix-4.2.5.tar.gz
cd zabbix-4.2.5
./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 --with-openssl --with-ssh2 --with-iconv --with-iconv-include --with-iconv-lib --with-libpcre --with-libpcre-include --with-libpcre-lib --with-libevent --with-libevent-include --with-zlib --with-zlib-include --with-zlib-lib --with-libpthread --with-libpthread-include --with-libpthread-lib --with-libevent-lib --with-ldap
（./congfigure提示缺少java环境，把/usr/local/java/jdk1.6.0_37/bin/此路径加入到/etc/profile文件中即可）
make && make install
4.修改配置参数（zabbix_agentd.conf的配置信息也多了，建议手动改）
cp /usr/local/zabbix.bak/etc/zabbix_agentd.conf /usr/local/zabbix/etc/zabbix_agentd.conf
cp -r /usr/local/zabbix.bak/etc/zabbix_agentd.conf.d /usr/local/zabbix/etc/
cp -r /usr/local/zabbix.bak/scripts /usr/local/zabbix/
mv /usr/local/zabbix/sbin/zabbix_java /usr/local/zabbix/sbin/zabbix_java_bk
cp -r /usr/local/zabbix.bak/sbin/zabbix_java /usr/local/zabbix/sbin/
vi /usr/local/zabbix.bak/etc/zabbix_server.conf

mv /etc/init.d/zabbix_agentd_bak /etc/init.d/zabbix_agentd
5.修改网页参数
mkdir /usr/local/nginx/html/zabbix
cp -a 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
##修改ip地址即可
chown -R zabbix.zabbix /usr/local/nginx/html/zabbix/
chmod -R 755 /usr/local/nginx/html/zabbix/
6.启动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 或者 service nginx restart
/etc/init.d/zabbix_server start
/etc/init.d/zabbix_agentd start
/usr/local/zabbix/sbin/zabbix_java/startup.sh
7.观察日志
