台主机：
192.168.13.54 192.168.13.55 192.168.13.56 192.168.13.57
2个vip：
192.168.13.59 192.168.13.60
启动mysql时需要同时启动keepalived
service mysql start
导出zabbix库
mysqldump -uzabbix -pZabbix1344 zabbix > /home/app/zabbix.sql
导入zabbix库
nohup mysql -uzabbix -pZabbix1344 zabbix < /home/app/zabbix.sql &
一、数据库高可用
192.168.13.56和192.168.13.57的mysql的root密码为zabbix@1344
安装的mysql-server版本为5.7
dpkg -l | grep mysql apt-get install mysql-server service mysql stop vim /etc/mysql/my.cnf [mysqld] skip-name-resolve max_connections = 1000 bind-address = 0.0.0.0 server-id = 1 #192.168.13.56设置为1，192.168.13.57设置为2 log-bin = /var/log/mysql/mysql-bin.log binlog-ignore-db = mysql,information_schema auto-increment-increment = 2 auto-increment-offset = 1 slave-skip-errors = all user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp lc-messages-dir = /usr/share/mysql skip-external-locking key_buffer_size = 16M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 8 myisam-recover-options = BACKUP query_cache_limit = 1M query_cache_size = 16M log_error = /var/log/mysql/error.log expire_logs_days = 5 max_binlog_size = 100M [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 syslog service mysql start
配置192.168.13.56
mysql -u root -pzabbix@1344 show master status; +------------------+----------+--------------+--------------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+--------------------------+-------------------+ | mysql-bin.000001 | 154 | | mysql,information_schema | | +------------------+----------+--------------+--------------------------+-------------------+ GRANT REPLICATION SLAVE ON *.* TO 'replication'@'192.168.13.%' IDENTIFIED BY 'replication'; flush privileges; change master to master_host='192.168.13.57', master_user='replication', master_password='replication', master_log_file='mysql-bin.000002', master_log_pos=154; start slave;
配置192.168.13.57
mysql -u root -pzabbix@1344 show master status; +------------------+----------+--------------+--------------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+--------------------------+-------------------+ | mysql-bin.000001 | 154 | | mysql,information_schema | | +------------------+----------+--------------+--------------------------+-------------------+ GRANT REPLICATION SLAVE ON *.* TO 'replication'@'192.168.13.%' IDENTIFIED BY 'replication'; flush privileges; change master to master_host='192.168.13.56', master_user='replication', master_password='replication', master_log_file='mysql-bin.000002', master_log_pos=154; start slave;
配置完成后在两台主机上都执行
show slave status\G;
查看Slave_IO和Slave_SQL是否为YES
在192.168.13.56上执行
mysql -pzabbix@1344 create database zabbix character set utf8 collate utf8_bin; grant all privileges on zabbix.* to zabbix@'%' identified by 'Zabbix1344'; grant all privileges on zabbix.* to zabbix@localhost identified by 'Zabbix1344'; flush privileges;
在192.168.13.57上测试是否添加账号密码和zabbix库成功
mysql -uzabbix -pZabbix1344 show databases;
在192.168.13.57上创建和删除数据库，看192.168.13.56是否同步
CREATE DATABASE my_db1; show databases; DROP DATABASE my_db1;
192.168.13.56和192.168.13.57安装keepalived
apt-get install keepalived
查看是否加载ip_vs模块到内核，如果没有加载会导致VIP转移失败
lsmod | grep ip_vs modprobe ip_vs modprobe ip_vs_wrr
192.168.13.56设置
vim /etc/keepalived/keepalived.conf

}
}192.168.13.56和192.168.13.57都配置
vim /etc/keepalived/mysql.sh #!/bin/bash pkill keepalived chmod +x /etc/keepalived/mysql.sh service keepalived start
查看Mysql客户端最大连接数
show variables like 'max_connections';
二、zabbix_server高可用
1、配置部署keepalived
在192.168.13.54和192.168.13.55上配置
apt-get install keepalived apt-get install open-jdk
查看是否加载ip_vs模块到内核，如果没有加载会导致VIP转移失败
lsmod | grep ip_vs modprobe ip_vs modprobe ip_vs_wrr vim /etc/keepalived/mysql.sh #!/bin/bash pkill keepalived chmod +x /etc/keepalived/mysql.sh
配置192.168.13.54的keepalived
vim /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
iot@iot.com
}
notification_email_from iot@iot.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id ZABBIX_HA
}
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 55
priority 100
advert_int 1
nopreempt
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.13.59
}
}
virtual_server 192.168.13.59 10051 {
delay_loop 2
persistence_timeout 50
protocol TCP
real_server 192.168.13.54 10051 {
weight 3
notify_down /etc/keepalived/zabbix.sh
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
}配置192.168.13.55的keepalived
vim /etc/keepalived/keepalived.conf
! Configuration File for keepalived
global_defs {
notification_email {
iot@iot.com
}
notification_email_from iot@iot.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
router_id ZABBIX_HA
}
vrrp_instance VI_1 {
state BACKUP
interface eth0
virtual_router_id 55
priority 90
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.13.59
}
}
virtual_server 192.168.13.59 10051 {
delay_loop 2
persistence_timeout 50
protocol TCP
real_server 192.168.13.55 10051 {
weight 3
notify_down /etc/keepalived/zabbix.sh
TCP_CHECK {
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
}
}2、配置部署zabbix_server
从192.168.13.45复制了/opt/zabbix_home/到192.168.13.54和192.168.13.55上，目录位置没变
在192.168.13.54和192.168.13.55上都执行
修改zabbix前端对应的数据库
vim /opt/zabbix_home/frontends/php/conf/zabbix.conf.php $DB['SERVER'] = '192.168.13.60';
修改zabbix_server指向的数据库
vim /opt/zabbix_home/conf/zabbix/zabbix_server.conf DBHost=192.168.13.60
修改zabbix_server的SourceIP指向虚拟IP
vim /opt/zabbix_home/conf/zabbix/zabbix_server.conf SourceIP=192.168.13.59
解决依赖关系 ldd $(which /opt/zabbix_home/app/httpd/bin/httpd) ldd $(which /opt/zabbix_home/sbin/zabbix_server)
apt-get install libaprutil1 apt-get install libpcre3 apt-get install libmysqlclient18:amd64 apt-get install libnet-snmp-perl apt-get install snmp apt-get install snmp-mibs-downloader find / -name "libpcre.so*" ln -sv /lib/x86_64-linux-gnu/libpcre.so.3.13.3 /lib/x86_64-linux-gnu/libpcre.so.1
启动web
/opt/zabbix_home/app/httpd/bin/httpd -k start
启动server
/opt/zabbix_home/sbin/zabbix_server -c /opt/zabbix_home/conf/zabbix/zabbix_server.conf
查看server日志
tail -200f /opt/zabbix_home/logs/zabbix/zabbix_server.log
启动keepalived
service keepalived start
keepalived开启日志
vim /etc/default/keepalived DAEMON_ARGS="-D -d -S 0"
解决微信python脚本依赖
apt-get install python-simplejson /opt/zabbix_home/app/zabbix/share/zabbix/alertscripts/wechat.py 1 1 1
三、zabbix-proxy部署
1、下载安装proxy包，解决依赖关系
192.168.13.45上执行
cd /opt wget http://repo.zabbix.com/zabbix/3.0/ubuntu/pool/main/z/zabbix/zabbix-proxy-mysql_3.0.4-1+trusty_amd64.deb dpkg -i zabbix-proxy-mysql_3.0.4-1+trusty_amd64.deb
2、导入数据库
192.168.13.44上执行
mysql -uroot -p mysql > create database zabbix_proxy character set utf8 collate utf8_bin; grant all privileges on zabbix_proxy.* to zabbix@'%' identified by 'Zabbix1344'; grant all privileges on zabbix_proxy.* to zabbix@localhost identified by 'Zabbix1344'; flush privileges;
192.168.13.45上执行
zcat /usr/share/doc/zabbix-proxy-mysql/schema.sql.gz | mysql -h192.168.13.44 -uzabbix -p"Zabbix1344" zabbix_proxy
3、修改proxy的配置文件
vim /etc/zabbix/zabbix_proxy.conf Server=192.168.13.59 ServerPort=10051 Hostname=Zabbix_proxy LogFile=/var/log/zabbix/zabbix_proxy.log PidFile=/var/run/zabbix/zabbix_proxy.pid DBHost=192.168.13.44 DBName=zabbix_proxy DBUser=zabbix DBPassword=Zabbix1344 DBPort=3306 ConfigFrequency=600 DataSenderFrequency=3 StartPollers=100 StartPollersUnreachable=50 StartTrappers=30 StartDiscoverers=6 JavaGateway=127.0.0.1 JavaGatewayPort=10052 StartJavaPollers=5 CacheSize=320M StartDBSyncers=20 HistoryCacheSize=512M Timeout=4 ExternalScripts=/usr/lib/zabbix/externalscripts FpingLocation=/usr/bin/fping Fping6Location=/usr/bin/fping6 LogSlowQueries=3000 AllowRoot=1
4、修改server端和proxy端的hosts
vim /etc/hosts 192.168.13.45 Zabbix_proxy
5、启动zabbix_java监控jmx
/opt/zabbix_home/app/zabbix/sbin/zabbix_java/startup.sh
6、启动zabbix-proxy
service zabbix-proxy start
7、zabbix_proxy首次更新等待时间长用命令刷新解决 zabbix_proxy -R config_cache_reload
