系统准备

[!warning] -操作系统 : CentOS7

开始部署

[!important]- 前期准备工作
关闭防火墙

systemctl stop firewalld.service
systemctl disable firewalld.service

关闭 selinux

setenforce 0

配置 aliyun 源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
curl -o /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

下载基础包

yum update

yum install -y bash-com* vim wget unzip

[[#MYSQL]]

下载 git 拉取项目 ，项目地址在 #项目部署实操

yum install -y git

yum install -y mariadb-server mariadb

编辑MySQL配置文件 /etc/my.cnf，添加以下内容：

[!Warning] 注意添加到【mysqld】所属组 ！！！

[mysqld]
server-id=1
log-bin=/data/mysql/log/mysql-bin-master  #开启log-bin日志

为Mysql创建主log-bin目录

mkdir  -p /data/mysql/log/
chown mysql.mysql -R /data/mysql/log

启动

sudo systemctl start mariadb --now
mysqladmin -u root password "root"
mysql -uroot -proot

[!Warning] 上述操作需要在主从上分别执行

创建mall仓库和授权，【在主库上】

create database mall;
grant all privileges on mall.* to admin@'%' identified by 'admin';
flush privileges;

建立给从数据库授权

grant replication slave on *.* to slave@'192.168.30.%' identified by 'root';
flush privileges;

[!Warning] 导入数据库并发送给从数据库，从库在导入时应先按上述将数据库先行建立

use mall
source /root/mall/document/sql/mall.sql

[!Warning] 记住这串数字 661406

####看到两个yes代表主从搭建完成

最后，设置让其开机自启动

systemctl enable mariadb
再次配置成为双主双从

master-slave配置

vim /etc/my.conf

server-id = 2
log-bin=/data/mysql/log/mysql-bin-master

创建mysql 的log-bin目录

mkdir -p /data/mysql/log
chown mysql.mysql -R /data

重启

 systemctl restart mariadb

mysql -uroot -proot -e "grant replication slave on *.* to slave@'%' identified by 'root'"
mysql -uroot -proot -e "flush privileges"

查看master 状态

mysql -uroot -proot -e "show master status"

mysql-master配置

vim /etc/my.conf

relay-log=/data/mysql/log/relay-log-bin
relay-log-index=/data/mysql/log/slave-relay-bin.index

重启

systemctl restart mariadb

mysql数据库从配置

stop slave;

change master to master_host='192.168.30.126',master_user='slave',master_password='root',master_log_file='mysql-bin-master.000001',master_log_pos=600;

start slave;
show slave status\G
为 mysql 集群配置 vip

安装 keepalived

yum install keepalived -y

keepalived 配置

mv /etc/keepalived/keepalived.conf{,.bak}
vim /etc/keepalived/keepalived.conf

global_defs {
    router_id MYSQL_MS
}
vrrp_script chk_mysql {
    script "/etc/keepalived/check_mysql.sh"
    interval 5
    weight -5
    fall 2
    rise 2
}
vrrp_instance VI_1 {
    state MASTER
    interface ens32
    virtual_router_id 51
    priority 120
    advert_int 1
    authentication {
        auth_type PASS
        auth_pass 123456
    }
    virtual_ipaddress {
        192.168.30.60
    }
    track_script {
        chk_mysql 
    }
}

主从的 keepalived 配置文件的差异

state MASTER -----》 state BACKUP
priority 120 # 从比主低就行

健康检查脚本[在主上]

vim /etc/keepalived/check_mysql.sh

#!/bin/bash
MYSQL_HOST="127.0.0.1"
MYSQL_USER="root"
MYSQL_PASSWORD="root"
VIP="192.168.30.60"  # 定义VIP变量
INTERFACE="ens32"  # 定义网络接口变量

# Check MySQL is running
mysql_status=$(mysqladmin ping -h${MYSQL_HOST} -u${MYSQL_USER} -p${MYSQL_PASSWORD} 2>&1)
if [ $? -ne 0 ] && [ ip addr show | grep -q "${VIP}" ]; then
    ip addr del ${VIP} dev ${INTERFACE}
    exit 1
fi

ip addr add ${VIP} dev ${INTERFACE}
exit 0

[!NOTE] 脚本大致的意思就是检测该主机是否有 vip 并且服务是否是正常的，如果服务不正常并且 vip 还在的话就删除该 vip ，[以下的服务配置健康检查脚本的逻辑基本一样]

chmod +x /etc/keepalived/check_mysql.sh

启动脚本

cd /etc/keepalived
./check_mysql.sh

启动

sudo systemctl enable keepalived
sudo systemctl start keepalived

在主节点上

ip a

在这里插入图片描述

vip 已经生成

将主宕机

systemctl stop mariadb.service

主节点挂机之后，vip 实现漂移

在这里插入图片描述

当主恢复后

systemctl restart mariadb.service

[[#mongodb]]

[!warning] MongoDB 采用 二进制 的安装方式

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-5.0.23.tgz

tar -zxvf mongodb-linux-x86_64-rhel70-5.0.23.tgz -C /usr/local/

mv /usr/local/mongodb-linux-x86_64-rhel70-5.0.23/ /usr/local/mongodb

ln -s /usr/local/mongodb/bin/* /usr/local/bin/

mkdir -p /data/mongodb/{data,log}

新增配置文件

vim /usr/local/mongodb/mongodb.conf

[!Warning]- 单机模式下，请先注释 或者在启动前先将下面的密钥配置了再来启动

security:
 authorization: enabled
 keyFile: /data/mongodb/mongo.key
 clusterAuthMode: keyFile 

storage:
  dbPath: /data/mongodb/data
systemLog:
  destination: file
  path: /data/mongodb/log/mongodb.log
  logAppend: true

processManagement:
  fork: true
security:
  authorization: enabled
  keyFile: /data/mongodb/mongo.key
  clusterAuthMode: keyFile

新增 service 脚本

vim /usr/lib/systemd/system/mongodb.service

[Unit]

After=network.target

[Service]
Type=forking
ExecStart=/usr/local/mongodb/bin/mongod --config /usr/local/mongodb/mongodb.conf
PrivateTmp=true

[Install]
WantedBy=multi-user.target

启动

systemctl start mongodb
systemctl enable mongodb

[!warning] 以上是单机实例

进入文件夹

cd /data/mongodb

在主上生成密钥

openssl rand -base64 756 > /data/mongodb/mongo.key
chmod 400 /data/mongodb/mongo.key
useradd -M -s /sbin/nologin mongodb
chown mongodb.mongodb -R /data/mongodb/

在传输之前，先在各个节点都把用户建立好

for i in 5 160 ; do scp mongo.key root@192.168.58.$i:/data/mongodb/ ;done

for i in 5 160 ; do scp /usr/local/mongodb/mongodb.conf root@192.168.58.$i:/usr/local/mongodb ;done

都重启一下

systemctl restart mongodb.service
在主节点上无认证登录
mongo

use admin

安装 启动 RabbitMQ 服务器

sudo yum install rabbitmq-server -y
sudo systemctl enable rabbitmq-server --now
尝试查看集群状态：
rabbitmqctl cluster_status

[!Warning] 此时只有单节点显示是正确的，因为还未加入节点，报错则首先确保~/.erlang.cookie 与/var/lib/rabbitmq/.erlang.cookie一致，若无/.erlang.cookie,则可重启试试，亲测有效：

sudo systemctl restart rabbitmq-server

配置节点域名

cat >> /etc/hosts << EOF
192.168.30.212 rabbit1
192.168.30.127 rabbit2
EOF

确保所有节点上.erlang.cookie文件内容一致，建议各机子检查一下：

scp /var/lib/rabbitmq/.erlang.cookie 192.168.30.127:/var/lib/rabbitmq/

将rabbit2节点加入集群当中，在rabbit2上操作：

[!Warning] rabbit1 是主机名，这个地方不能使用 ip 地址代替

rabbitmqctl stop_app
rabbitmqctl reset 
rabbitmqctl join_cluster --disc rabbit@rabbit1 //--disc表示磁盘节点（默认也是磁盘节点） rabbitmqctl start_app

需要说明的是，在执行join_cluster时，出现如下报错，是正常的：

00:01:14.620 [error] Failed to create a per-user tracked connection table for node :rabbit@node2: {:node_not_running, :rabbit@node2}

再次查看集群状态：

rabbitmqctl cluster_status
Cluster status of node rabbit@rabbit2 ...
Basics

Cluster name: rabbit@rabbit2

Disk Nodes

rabbit@rabbit1
rabbit@rabbit2

Running Nodes

rabbit@rabbit1
rabbit@rabbit2

创建vhost，用户，并授权：

rabbitmqctl add_vhost /mall
sudo rabbitmqctl add_user mall mall
sudo rabbitmqctl set_user_tags mall publisher
sudo rabbitmqctl set_permissions -p /mall mall ".*" ".*" ".*"

查看情况：

使用 LVS + keepalived 给 rabbitmq 做高可用

network.host: 0.0.0.0   #修改监听IP
http.port: 9200

xpack.security.enabled: false   #关闭安全认证，否则使用http访问不到es,第一次启动没有这个参数，第二次启动再关闭
