1.停止zabbix,php服务

2.备份zabbix数据库，忽略history,trends相关表

mysqldump --opt -R -uzabbix -p zabbix \

--ignore-table=zabbix.history \

--ignore-table=zabbix.history_log \

--ignore-table=zabbix.history_str \

--ignore-table=zabbix.history_text \

--ignore-table=zabbix.history_uint \

--ignore-table=zabbix.trends \

--ignore-table=zabbix.trends_uint | gzip > zabbix_`date +'%Y%m%d%H%M%S'`.sql.gz

或者直接mysqldump -uzabbix -pzabbix zabbix >zabbix.sql

3.升级php到5.6

(1)service php-fpm stop

(2)mv /usr/local/php /usr/local/php5.3

(3)下载5.6版本，编译安装(注：always_populate_raw_post_data = -1,修改session.auto_start = 0，如果session报错，查看下session保存目录是否具有权限)

tar zvxf php-5.6.29.tar.gz

cd php-5.6.29/

mkdir /usr/local/php

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql-sock=/tmp/mysql.sock --with-pdo-mysql=/usr/local/mysql --with-gd --with-png-dir=/usr/local/libpng --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/local/freetype --with-xpm-dir=/usr/ --with-zlib-dir=/usr/local/zlib  --with-iconv --enable-libxml --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-opcache --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --enable-session --with-mcrypt --with-curl --enable-ctype

make ZEND_EXTRA_LIBS='-liconv' && make install

cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm -r

chmod a+x /etc/rc.d/init.d/php-fpm

cp /usr/local/php5.3/etc/php.ini /usr/local/php/etc -f

cp /usr/local/php5.3/etc/php-fpm.conf /usr/local/php/etc -f

service php-fpm restart

4.升级libcurl到7.47

rpm -ivh http://mirror.city-fan.org/ftp/contrib/yum-repo/city-fan.org-release-1-13.rhel6.noarch.rpm

yum upgrade libcurl

rpm -e city-fan.org-release

然后通过curl -V验证是否是7.47版本

5.升级zabbix3.0

(1)pkill zabbix

(2)mv /usr/local/zabbix  /usr/local/zabbix2

(3)tar zvxf zabbix-3.0.4.tar.gz

(4)安装3.0

cd zabbix-3.0.4

./configure --prefix=/usr/local/zabbix --enable-server --enable-agent --with-net-snmp --with-libcurl --enable-proxy --with-mysql=/usr/bin/mysql_config

make &&make install

(5)替换旧的web目录

mv /data/zabbixdir /data/zabbixdir2.0

mkdir /data/zabbixdir

cd /usr/local/zabbix/

cp -rf zabbix-3.0.4/frontends/php/* /data/zabbixdir/(自己设定的web目录)

cp -f /data/zabbixdir2.0/conf/zabbix.conf.php /data/zabbixdir/conf/zabbix.conf.php

(6)配置文件修改并启动

cp /usr/local/zabbix2/etc/zabbix_server.conf /usr/local/zabbix/etc/

/usr/local/zabbix/sbin/zabbix_server

/usr/local/zabbix/sbin/zabbix_agentd
