mysql+zabbix升级方案(下)

文章上篇跳转以下链接查看 https://forum.lwops.cn/article/381

4.4     升级备机到zabbix6.0版本

# tar xf LWSetup.tar.gz

# cd LWSetup/

# vim LW_install.sh

##修改如下配置文件中标黄部分,分别为数据库IP备库IP)、库名、用户、密码

# sh LW_install.sh MYSQL 2>&1 | tee install.log

##选择install安装

# tailf /itops/zabbix/logs/zabbix_server.log

##安装完成后会自启server进程,可以通过打印日志输出确认数据库升级进度

# 服务正常运行时,应该有以下监听端口

9000:      php-fpm

10051:     server

10052:     zabbix-java

80:          nginx

 

[root@server-2 ~]# tar xf LWSetup.tar.gz

[root@server-2 ~]# cd LWSetup/

[root@server-2 LWSetup]# vim LW_install.sh

 

 

##全局变量

export ZBXServer="${host_ip}"      #采集服务器ip地址,HAVIP

export WEB_IP="${host_ip}"         #WEB服务器的,HAVIP

export Server_DBHost="192.168.164.221"  #server数据库ip地址

 

elif [ $1 = MYSQL ];then

# MySQL

export MysqlPath="/itops/mysql" #MySQL安装路径

export DataPath="/data/mysql"       #MySQL数据目录

export ETC="/etc"                   #MySQL配置文件路径

export SQLUSER="root"               #MySQL安装初始化后设置帐号

export SQLPASSWORD="ITMY_p@ssw0rd"       #MySQL安装初始化后设置#MySQL安装初始化后端口号

export Server_DBPort="3306"         #MySQL安装初始化后端口号

export SQLZBUSER="zabbix"     #serverproxy对接的msyql数据库用户名

export SQLZBPASSWD="p@ssw0rd"   #serverproxy对接的mysql数据库密码

export MySQLBackage="mysql-8.0.28-el7-x86_64.tar.gz"

export BOOSTBackage="boost_1_59_0.tar.gz"

 

[root@server-2 LWSetup]# sh LW_install.sh MYSQL 2>&1 | tee install.log

                                                   **...开始安装基础环境产品

                                                   **...输入 install,即可选择安装zabbxi server环境mysql数据库或postgresql数据库

                                                         包含的环境LNMP(数据库根据选择而定)oracle clientpython3ansiblezabbix serverzabbix agentd

                                                   **...输入 custom,自定义选择安装组件

        **...输入quit,退出安装

请输入你的选择 install|custom|quit: install

你的选择是 install

 

开始执行 lnmp_install.sh

root $ yum install -y gcc gcc-c++ automake pcre pcre-devel zlip zlib-devel openssl openssl-devel

 

 

root $ sed -i "s@localhost@192.168.164.223@g" /itops/zabbix/share/zabbix/alertscripts/LWSendAlert/api.conf

root $ chown -R itops:itops /itops/zabbix/share/zabbix/alertscripts/

root $ chmod -R 777 /itops/zabbix/share/zabbix/alertscripts/LWSendAlert

 

========================================[启动服务]========================================

 

Restarting zabbix_server (via systemctl):  [  OK  ]

Restarting zabbix_agentd (via systemctl):  [  OK  ]

4.5     启用备机pcsd服务

# service pcsd start

# pcs resource show

# pcs resource delete ZabbixServer

# pcs resource create ZabbixServer systemd:zabbix_server op monitor interval=20s --group server_group

   ##通过第二个show命令获取服务名,进行资源删除重新添加

# pcs status

4.6     升级主机到zabbix6.0版本

参考章节4.4

4.7     启用备库keepalived

# yum install keepalived -y

# cp -f /data/keepalived.conf /etc/keepalived/keepalived.conf

# vim /etc/keepalived/keepalived.conf

  ## 调整主备库keepalived优先级参数,使备库为“后续主库”使用

# service keepalived start

# pcs cluster stop --all && pcs cluster start --all  ## pcs集群重启命令

 

 

[root@db-2 mysql_8]# yum install keepalived -y

[root@db-2 mysql_8]# cp -f /data/keepalived.conf /etc/keepalived/keepalived.conf

[root@db-2 mysql_8]# vim /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

   router_id MYSQL_HA #标识相同

}

vrrp_instance VI_1 {

    state BACKUP #都设置为BACKUP

    interface ens33

    virtual_router_id 90

    priority 100 #优先级,backup设置比主小,同为backup时优先级别越高,就会主动去抢VIP

    nopreempt

    advert_int 1 #主备心跳检查间隔

    authentication {

        auth_type PASS

        auth_pass 9191

}

unicast_src_ip 192.168.164.221   #表示发送VRRP单播报文使用的源IP地址

unicast_peer {

                  192.168.164.220     #表示对端接收VRRP单播报文的IP地址

                }

    virtual_ipaddress {

        192.168.164.224 dev ens33 scope global #VIP地址

    }

}

virtual_server 192.168.164.224 3306 {

    delay_loop 6

    #lb_algo rr #LVS轮询算法

    #lb_kind NAT

    #nat_mask 255.255.255.0

    persistence_timeout 50 #回话保持时间

    protocol TCP

    real_server 192.168.164.221 3306 {

        weight 3

        notify_down /etc/keepalived/mysql.sh #mysqdown时,执行此脚本,杀死keepalived实现切换

        TCP_CHECK {

            connect_timeout 3 #连接超时

            nb_get_retry 3 #重试次数

            delay_before_retry 3 #重试间隔时间

        }

    }

}

 

[root@db-2 mysql_8]# service keepalived start

Redirecting to /bin/systemctl start keepalived.service

 

 

 

4.8    关闭主库keepalived,同时修改主备机zabbix_serverDB指向VIP

MYSQL库上操作:

# service keepalived stop

# vim /etc/keepalived/keepalived.conf

  ## 调整主备库keepalived优先级参数,使主库为“后续备库”使用

主备server上操作:

# vim /itops/zabbix/etc/zabbix_server.conf

# vim /itops/nginx/html/zabbix/conf/zabbix.conf.php

 

 

[root@db-1 ~]# service keepalived stop

Redirecting to /bin/systemctl stop keepalived.service

[root@db-1 ~]# vim /etc/keepalived/keepalived.conf

! Configuration File for keepalived

global_defs {

   router_id MYSQL_HA #标识相同

}

    state BACKUP #都设置为BACKUP

    interface ens33

    virtual_router_id 90

    priority 90 #优先级,backup设置比主小,同为backup时优先级别越高,就会主动去抢VIP

    #nopreempt #不主动抢占资源,只在master这台优先级高的设置,backup不设置,当master恢复时,不把VIP抢占回来

    advert_int 1 #主备心跳检查间隔

    authentication {

        auth_type PASS

                }

    virtual_ipaddress {

4.9     升级主库到mysql8版本

可不保留原数据直接升级mysql8,后续步骤从备库全量备份并配置主备,安装过程参考《mysql+zabbix升级方案(上)》章节4.3

4.10     全量备份备库数据到主库

#导出

mysqldump --all-databases -uroot -p --add-drop-table --skip-lock-tables --single-transaction --flush-logs --hex-blob --master-data=2 > mysqldump.sql

#导入

mysql -uroot -p

source /root/mysqlbak.sql
