一 keeplived 高可用
| 192.168.11.11 | nginx keeplived |
| 192.168.11.12 | nginx keeplived |
两台均编译安装服务器
1 主服务器修改文件：
2 备服务器修改文本
scp keepalived.conf 192.168.11.12:/etc/keepalived/
3 给主服务器添加虚拟ip
ifconfig ens33:0 192.168.11.188 netmask 255.255.255.255
ifconfig ens33: 192.168.11.188/32
4 去真机windows添加虚拟ip
192.168.11.188 www.benet.com www.kgc.com
5 添加脚本
6执行权限
chmod +x ng.sh
7 主服务器关闭nginx
systemctl stop nginx
8 去被服务器检测：
二 实验 动静分离
承接高可用
1先把关闭nginx启动
去浏览器上检测
在虚拟机nginx做静
一 编译安装tomcat：192.168.11.13
另一台tomcat也用此方法

实验： 做动静分离
| nginx | 192.168.11.11 |
| tomcat | 192.168.11.13 |
| tomcat | 192.168.11.14 |
1 三台机器分别安装 nginx（参考我 虎 赵） tomcat（我 虎 赵）
1 编译 反向代里 动静分离文本
去静态 也就是nginx添加文本

9 修改 Master01、Slave01、Slave02 节点的 Mysql主配置文件/etc/my.cnf
10 在 Master01、Slave01、Slave02 节点上都创建两个软链接
ln -s /usr/local/mysql/bin/mysql /usr/sbin/
ln -s /usr/local/mysql/bin/mysqlbinlog /usr/sbin/
ls /usr/sbin/mysql* #查看软连接
/usr/sbin/mysql /usr/sbin/mysqlbinlog
11 在 Master、Slave1、Slave2 节点上都进行主从同步的授权
grant replication slave on *.* to 'myslave'@'192.168.246.%' identified by '123123';
grant all privileges on *.* to 'mha'@'192.168.246.%' identified by 'manager';

grant all privileges on *.* to 'mha'@'slave1' identified by 'manager';
grant all privileges on *.* to 'mha'@'slave2' identified by 'manager';
flush privileges;
主从同时登陆
给从服务器授权slave01 服务器配置

从服务器验证
12 配置MHA所有组件，所有服务器上都安装 MHA 依赖的环境，首先安装 epel 源
yum install epel-release --nogpgcheck -y
yum install -y perl-DBD-MySQL \
> perl-Config-Tiny \
> perl-Log-Dispatch \
> perl-Parallel-ForkManager \
> perl-ExtUtils-CBuilder \
> perl-ExtUtils-MakeMaker \
> perl-CPAN
13 四台服务器安装环境
14 在所有服务器上必须先安装node组件，最后在MHA-manager节点上安装manager组件，因为manager依赖node组件。
在 MHA manager 节点上安装 manager 组件

14 创建 MHA 软件目录并拷贝配置文件，这里使用app1.cnf配置文件来管理 mysql 节点服务器
[root@elk01 mha4mysql-manager-0.57]#vim /usr/local/bin/master_ip_failover
[root@elk01 mha4mysql-manager-0.57]#mkdir /etc/masterha
[root@elk01 mha4mysql-manager-0.57]#vim /usr/local/bin/master_ip_failover
[root@elk01 mha4mysql-manager-0.57]#cp /opt/mha4mysql-manager-0.57/samples/conf/app1.cnf /etc/masterha
[root@elk01 mha4mysql-manager-0.57]#vim /etc/masterha/app1.cnf

hostname=192.168.11.13
port=3306
[server3]
hostname=192.168.11.14
port=330615 第一次配置需要在 Master 节点上手动开启虚拟IP地址
[root@master01 opt]# /sbin/ifconfig ens33:1 192.168.11.100/24
[root@master01 opt]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
16 在 manager 节点上测试 ssh 无密码认证
在 manager 节点上测试 ssh 无密码认证，如果正常最后会输出 successfully，如下所示。
masterha_check_ssh -conf=/etc/masterha/app1.cnf
17 在 manager 节点上测试 mysql 主从连接情况
在 manager 节点上测试 mysql 主从连接情况，最后出现MySQL Replication Health is OK 字样说明正常。如下所示。
输入它查看情况
[root@elk01 mha4mysql-manager-0.57]#masterha_check_repl -conf=/etc/masterha/app1.cnf
在 manager 节点上启动 MHA
nohup masterha_manager --conf=/etc/masterha/app1.cnf --remove_dead_master_conf --ignore_last_failover < /dev/null > /var/log/masterha/app1/manager.log 2>&1 &[root@elk01 mha4mysql-manager-0.57]#nohup masterha_manager --conf=/etc/masterha/app1.cnf --remove_dead_master_conf --ignore_last_failover < /dev/null > /var/log/masterha/app1/manager.log 2>&1 &
[1] 10192
[root@elk01 mha4mysql-manager-0.57]#ps -aux|grep manager
root 10192 0.5 0.5 297380 21752 pts/0 S 17:20 0:00 perl /usr/local/bin/masterha_manager --conf=/etc/masterha/app1.cnf --remove_dead_master_conf --ignore_last_failover
root 10295 0.0 0.0 112824 984 pts/0 S+ 17:21 0:00 grep --color=auto manager
在 manager 节点上查看 MHA 状态 和 MHA 日志，可以看到 master的地址
masterha_check_status --conf=/etc/masterha/app1.cnf[root@elk01 mha4mysql-manager-0.57]#masterha_check_status --conf=/etc/masterha/app1.cnf
app1 (pid:10192) is running(0:PING_OK), master:192.168.11.7
[root@elk01 mha4mysql-manager-0.57]#cat /var/log/masterha/app1/manager.log | grep "current master"
Sat Apr 20 17:20:56 2024 - [info] Checking SSH publickey authentication settings on the current master..
192.168.11.7(192.168.11.7:3306) (current master)
查看master 的 VIP 地址 192.168.10.200 是否存在
这个 VIP 地址不会因为 manager 节点停止 MHA 服务而消失。
故障模拟
#在 manager 节点上监控观察日志记录
tail -f /var/log/masterha/app1/manager.log
同时去Master 节点 master 上停止mysql服务
再去manager服务器上的日志查看
查看 slave1 是否接管 VIP，使用ifconfig
正常自动切换一次后，MHA 进程会退出。HMA 会自动修改 app1.cnf 文件内容，将宕机的 master 节点删除。查看 slave1 是否接管 VIP
故障修复
修复原来的master（即修复原来的主节点）
修复主从
在新的主库服务器 slave1 中查看二进制日志文件和同步点
show master status;
在原主库服务器 master执行同步操作，同步现在主库中的数据
change master to master_host='192.168.11.13',master_user='myslave',master_password='123',master_log_file='master-bin.000005',master_log_pos=154;
在 manager 节点上修改配置文件app1.cnf
重新把三台mysql节点服务器这个记录添加进去，因为它检测到主节点失效时候会自动删除主节点
将slave01添加为新的候选master01
在 manager 节点上启动 MHA
nohup masterha_manager --conf=/etc/masterha/app1.cnf --remove_dead_master_conf --ignore_last_failover < /dev/null > /var/log/masterha/app1/manager.log 2>&1 &

思 查看nginx_accrss日志
| 192.168.11.9 | es head kafba |
| 192.168.11.12 | logstash |
| 192.168.11.14 | logstash |
1 先开启es
2 在nginx_access 修改配置文件
cd /etc/logstash/conf.d/
ls
vim nginx_log.conf
systemctl restart logstash
systemctl status logstash
ls
logstash -f nginx_log.confinput {
file {
path => "/apps/nginx/logs/access.log"
type => "access"
start_position => "beginning"
}
file {
path => "/apps/nginx/logs/error.log"
type => "error"
start_position => "beginning"
}
}
output {
if [type] == "access" {
elasticsearch {
hosts => ["192.168.11.9:9200"]
index => "nginx_access-%{+YYYY.MM.dd}"
}
}
if [type] == "error" {
elasticsearch {
hosts => ["192.168.11.9:9200"]
index => "nginx_error-%{+YYYY.MM.dd}"
}
}
}
3 重启服务
五 查看mysql_error 日志
1先开启es head
[root@slave02 conf.d]# cat mysql_log.conf
input {
file {
path => "/usr/local/mysql/data/error.log"
start_position => "beginning"
sincedb_path => "/dev/null"
type => "mysql_error"
}
}
output {
elasticsearch {
hosts => ["192.168.11.9:9200"]
index => "mysql.error-%{+YYYY.MM.dd}"
}
}
[root@slave02 conf.d]# logstash -f mysql_log.conf
2 编译MySQL 上logstash文本
[root@slave02 ROOT]# cd /etc/logstash/
[root@slave02 logstash]# vim mysql_error.conf
[root@slave02 logstash]# systemctl restart mysql
[root@slave02 conf.d]# logstash -f mysql_error.conf 
六 两个域名访问同页面
| 192.168.11.11 | ha01 nginx |
| 192.168.11.12 | |
| 浏览器 |
1 在192.168.11.11 添加
[root@ha01 ~]# cd /apps/nginx/
[root@ha01 nginx]# ls
client_body_temp fastcgi_temp logs sbin uwsgi_temp
conf html proxy_temp scgi_temp
[root@ha01 nginx]# cd conf/
[root@ha01 conf]# vim nginx.conf
[root@ha01 conf]# cd /opt/html/
[root@ha01 html]# ls
index.html
[root@ha01 html]# cat index.html
ACB
[root@ha01 html]# cat /etc/host
cat: /etc/host: 没有那个文件或目录
[root@ha01 html]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.11.11 www.benet.com
192.168.11.12 www.kgc.com
2 去192.168.11.14添加
[root@ha02 opt]# cd html/
[root@ha02 html]# ls
[root@ha02 html]# cat /apps/nginx/conf/nginx.conf
[root@ha02 conf.d]# vim /etc/hosts
[root@ha02 opt]# cd html/
[root@ha02 html]# ls
index.html
[root@ha02 html]# cat index.html
ABC
给真机添加该访问的域名
3 去浏览器检测：
需要有个缓存时间
