CentOS6.5下Zabbix3.4至Zabbix4.0的升級步驟
一、查看當前各軟件版本號
OS層面
操作系統版本為centos6.5
[root@vm172-31-0-21 share]# cat /etc/redhat-release CentOS release 6.5 (Final)
內核版本為2.6.32，64bit
[root@vm172-31-0-21 share]# uname -a Linux vm172-31-0-21.ksc.com 2.6.32-504.30.3.el6.x86_64 #1 SMP Wed Jul 15 10:13:09 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
應用層面
PHP版本：5.6.40
[root@vm172-31-0-21 share]# php -v PHP 5.6.40 (cli) (built: Jan 12 2019 09:19:57) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
Nginx版本和編譯模塊
[root@vm172-31-0-21 share]# nginx -V nginx version: nginx/1.16.1 built by gcc 4.4.7 20120313 (Red Hat 4.4.7-23) (GCC) built with OpenSSL 1.0.1e-fips 11 Feb 2013 TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'
PHP-FPM版本
[root@vm172-31-0-21 share]# php-fpm -v PHP 5.6.40 (fpm-fcgi) (built: Jan 12 2019 09:22:33) Copyright (c) 1997-2016 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
業務層面
[root@vm172-31-0-21 share]# zabbix_server -V zabbix_server (Zabbix) 3.0.30 Revision f25037a887 24 February 2020, compilation time: Feb 27 2020 04:25:44 Copyright (C) 2020 Zabbix SIA License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html>.

二、備份
1、備份數據庫
數據庫全備時間比較長且文件交大，建議壓縮或者使用xtrabackup， 此處采用mysqldump。
mysqldump -uzabbix -pzabbix --opt --skip-lock-tables --database zabbix | gzip > zabbix_`date +'%Y%m%d%H%M%S'`.sql.gz
2、備份應用配置
mkdir /data/web-backup/ #創建一個空文件 cp /etc/php.ini /data/web-backup/ #PHP配置文件 cp /etc/php-fpm.d/www.conf /data/web-backup/ #PHP-fpm配置文件 cp /etc/nginx/nginx.conf /data/web-backup/ #Nginx配置文件
3、備份業務配置
mkdir /data/zabbix-backup/ #創建一個空文件 cp /etc/zabbix/zabbix_server.conf /data/zabbix-backup/ cp -R /usr/share/zabbix/ /data/zabbix-backup/ cp -R /usr/share/doc/zabbix-* /data/zabbix-backup/
三、升級Zabbix
1、停止服務
service zabbix-server stop service zabbix-agent stop service nginx stop
2、升級zabbix源
rpm -Uvh https://repo.zabbix.com/zabbix/4.0/rhel/6/x86_64/zabbix-release-4.0-2.el6.noarch.rpm
3、升級zabbix
yum clean all yum upgrade zabbix-sender zabbix-agent zabbix-proxy-mysql zabbix-java-gateway
注意：由於centOS6在zabbix4.0版本上無法直接yum upgrade，有些包在yum倉庫里面放入了deprecated文件，具體原因也未知，所以需要下載下來進行安裝。
可以直接一鍵升級：
rpm -Uvh zabbix-server-mysql-4.0.18-1.el6.x86_64.rpm zabbix-web-4.0.18-1.el6.noarch.rpm zabbix-web-mysql-4.0.18-1.el6.noarch.rpm
4、啟動服務
service zabbix-server start service zabbix-agent start service nginx start
5、升級后驗證
6、升級過程中遇到的問題
a、curl: (35) SSL connect error
解決方式：
yum -y update nss ldconfig
b、libevent-1.4.so.2()(64bit) is needed by zabbix-proxy-mysql-4.0.18-1.el6.x86_64
c、升級rpm包
rpm -Uvh zabbix-web-4.0.18-1.el6.noarch.rpm zabbix-web-mysql-4.0.18-1.el6.noarch.rpm
rpm -Uvh zabbix-server-mysql-4.0.18-1.el6.x86_64.rpm
d、字體修改
yum install wqy-microhei-fonts -y cp /usr/share/fonts/wqy-microhei/wqy-microhei.ttc /usr/share/zabbix/assets/fonts/graphfont.ttf
