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)

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 '-'

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

拉取kafka镜像#docker pull wurstmeister/kafka
创建容器#docker run -d --name kafka -p 9092:9092 --link zookeeper -e KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181 -e KAFKA_ADVERTISED_HOST_NAME=localhost -e KAFKA_ADVERTISED_PORT=9092 wurstmeister/kafka:latest
