Linux下数据库和中间件安装配置

项目采用亚马逊云服务器，需要SSH证书访问，

部署 zookeeper、kafka、redis、mysql、clichkhouse

其中zookeeper、kafka、redis采用docker部署

一、首先连接服务器(使用亚马逊云下载的pem密钥文件)

[HOST]# ssh -i AWS-Host.pem centos@18.25.99.1

[HOST]@ip-172-31-2-111~]$

sudo -i 切换到root权限

[HOST]@ip-172-31-2-111~]$ sudo -i

[root@ip-172-31-2-111~]#

二、解下来开始安装各个服务

yum安装java

[root@ip-172-31-2-111~]# yum -y install java-1.8.0-openjdk.x86_64

[root@ip-172-31-2-111~]# java -version

openjdk version "1.8.0_392"

OpenJDK Runtime Environment (build 1.8.0_392-b08)

OpenJDK 64-Bit Server VM (build 25.392-b08, mixed mode)

【linux安装mysql 8.0】

1、安装本地YUM源

[root@ip-172-31-2-111~]# yum -y localinstall https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm

2、安装mysql服务

yum -y install mysql-community-server

如果报错

Failing package is: mysql-community-client-8.0.32-1.el7.x86_64

GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

执行

[root@ip-172-31-2-111~]#rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022

3、启动MySql服务

（1）systemctl start mysqld

（2）systemctl enable mysqld

（3）service mysqld status

4、查看默认密码

[root@ip-172-31-2-111~]# grep 'temporary password' /var/log/mysqld.log

2023-11-21T07:40:19.629699Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost:;qVw3%rGIbql

5、登陆重置密码

先按照规则设置一个密码：

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'Zxc123456!';

修改密码规则和长度限制：

(3)修改mysql密码校验规则与密码长度(必须先修改密码，否则这个无法执行)

mysql> set global validate_password.policy=0;

mysql> set global validate_password.length=1;

再次修改容易记的密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '123456';

6、远程登录授权

update mysql.user set host='%' where user="root";

flush privileges;

select user,host from mysql.user;

7、用户授权

grant all privileges on *.* to 'root'@'%';

flush privileges;

【linux安装clickhouse】

1、下载以下rpm包

wget https://packages.clickhouse.com/rpm/stable/clickhouse-client-22.1.2.2-2.noarch.rpm

wget https://packages.clickhouse.com/rpm/stable/clickhouse-common-static-22.1.2.2-2.x86_64.rpm

wget https://packages.clickhouse.com/rpm/stable/clickhouse-server-22.1.2.2-2.noarch.rpm

2、安装，要输入默认用户密码

rpm -ivh *.rpm

算出随机密码和加密(绿色部分为明文，红色部分为密文放于xml文件 )

[root@ip-172-31-2-111~ clickhouse]# PASSWORD=(base64 \< /dev/urandom \| head -c8); echo "PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'
39YoaNiw
a674efe083d6590d0d8df13c822a945cf19d3bb65dda28651f8331223cd35cdc

可以在此编辑修改密码

vi /etc/clickhouse-server/users.d/default-password.xml

<clickhouse>

<users>

<default>

<password remove='1' />

<password_sha256_hex>a674efe083d6590d0d8df13c822a945cf19d3bb65dda28651f8331223cd35cdc </password_sha256_hex>

</default>

</users>

</clickhouse>

3、命令

启动service clickhouse-server start

重启service clickhouse-server restart

连接客户端：clickhouse-client --password

【docker安装 zookeeper】

#yum -y install docker

#service docker start

#docker pull zookeeper:3.8.0

创建容器

#docker run -d -p 2181:2181 --name zookeeper --restart always 3fae25920878
