服务器配置： 数据库rds、redis、nacos、nginx、node、git、域名、OSS、java、maven

安装Java\maven\nginx\Mysal

JAVA

• yum install java-1.8.0-openjdk :
• java -version
• vim /etc/profile.d/java.sh
• JAVA_HOME=“/usr/lib/jvm/java-1.8.0-openjdk”
• source /etc/profile.d/java.sh
• 验证：echo $JAVA_HOME ->输出目录即为正确

MAVEN

• yum install -y maven
• mvn --version
• vim /etc/maven/setting.xml

<localRepository>/opt/maven_repo</localRepository>
<mirror>
    <id>alimaven</id>
    <mirrorOf>central</mirrorOf>
    <name>aliyun maven</name>
    <url>https://maven.aliyun.com/repository/central</url>
</mirror>
<mirror> 
    <id>aliyun-maven</id> 
    <mirrorOf>*</mirrorOf> 
    <name>aliyun maven</name> 
    <url>http://maven.aliyun.com/nexus/content/groups/public</url> 
</mirror>

Nginx

• yum install -y nginx
• 端口开放
• nginx -s start

Mysql8

• yum localinstall https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
• systemctl start mysqld
• systemctl status mysqld
• grep ‘temporary password’ /var/log/mysqld.log（若无直接跳过）
• mysql -uroot -p
  • use mysql;
  • ALTER USER ‘root’@‘localhost’ IDENTIFIED BY ‘newpassword’;
• create user test_user@‘%’ identified by ‘password’;
  • ·%· 表示可以在任意远程主机登录
• grant all on databasename.tablename to ‘username’@‘%’ with grant option;
  • privileges可以为select/ insert /update/all
  • tablename可以为*
  • with grant option 【该用户可授权】
• flush privileges; 刷新权限表
• SET PASSWORD FOR ‘username’@‘host’ = PASSWORD(‘newpassword’);
• SET PASSWORD = PASSWORD(“newpassword”); --当前登陆用户
• REVOKE privilege ON databasename.tablename FROM ‘username’@‘host’; -撤销用户权限
• drop user ‘username’@‘host’ --删除用户

安装git

• yum install git => git --version

安装配置nacos

• 下载 nacos-server-$version.zip 包
• tar -xvf nacos-server-$version.tar.gz
• 默认情况为单实例启动,本服务器设置集群

nacos集群设置

• mysql创建数据库 nacos
• 将nacos-mysql脚本倒入到数据库
• 修改config/application.properties
  • If use MySQL as datasource: 注释打开

spring.datasource.platform=mysql

• 设置用户名密码为mysql新建的用户/密码
• 配置cluster
  • cp cluster.conf.example cluster.conf

172.31.0.8:8848
172.31.0.8:8850
172.31.0.8:8860

• 将 /data/nacos/nacos 改名称 mv nacos/ nacos8848
• cp -r nacos8848 nacos8860
• cp -r nacos8848 nacos8850
• 修改8860与8850端口号：application.properties
• 然后分别启动
• 接着看之前单实例的配置：–本地没配置，如果有配置应该先倒出然后再倒入最新启动的

• nginx配置–直接放入到nginx.conf即可

upstream nacos_cluster{
	server 127.0.0.1:8848;
	server 127.0.0.1:8849;
	server 127.0.0.1:8850;
}

server {
	listen 8848;
	server_namelocahost;
	localtions / {
		proxy_pass http://nacos_cluster;
		proxy_set_header Host $host:$server_port;
	}
}

nginx重启即可。

安装redis

• yum install redis
• systemctl start redis
• systemctl enable redis [开机启动]
• /etc/redis.conf [允许远程连接 注释掉 bind:127.0.0.1]
• # requirepass foobared [密码登录：注释掉该行，将footbared改为 your password]
• 修改 daemonize no（第128行） 为 daemonize yes
• 开放安全组：6379
• redis-server /etc/redis.conf 启动！

telnet

安装NVM

• 安装CentOS系统上的默认nodejs: yum module install nodejs
• 安装nvm: curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash

安装pm2

服务器上node版本为14 安装pm2 npm i pm2 -g

安装Docker

配置mysql/redis/tomcat/nginx

• yum install -y yum-utils device-mapper-persistent-data lvm2
• yum-config-manager --add-repo
• yum install docker-ce -y
• systemctl start docker
• docker -v
• 设置开机启动: chkconfig docker on
• systemctl enable docker

Docker应用部署

• java:8
  • docker pull java:8
• mysql
  • cd /root
  • mkdir mysql

docker run -id \
-p 3307:3306 \
--name=c_mysql \
-v $PWD/conf:/etc/mysql/conf.d \
-v $PWD/logs:/logs \
-v $PWD/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=****** \
mysql:5.7

• nginx
  • cd /root
  • mkdir nginx
  • cd nginx
  • mkdir conf
  • **cd conf **
  • vim nginx.conf [内容见下方]
  • cd /root
  • 新建容器

docker run -id --name=c_nginx \
-p 8880:80 \
-v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \
-v $PWD/logs:/var/log/nginx \
-v $PWD/html:/usr/share/nginx/html \
nginx

// /root/nginx/conf/nginx.conf
user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    `#`tcp_nopush     on;

    keepalive_timeout  65;

    `#`gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

• tomcat
• cd /root
• mkdir tomcat

docker run -id --name=c_tomcat \
-p 8080:8080 \
-v $PWD:/usr/local/tomcat/webapps \
tomcat

// 在/root/tomcat/test/index.html，开放8080端口测试

• redis
  • redis由于需要配置密码登录以及远程连接等，而服务器已配好.
  • **因此这里不再安装，**下面为启动命令(没有文件映射)

docker run -id --name=c_redis -p 6379:6379 redis:5.0
测试：redis-cli.exe -h 192.168.149.135 -p 6379

Docker搭建私有仓库

• docker pull registry
• docker run -id --name=registry -p 5000:5000 registry
• 输入地址 http://私有仓库服务器ip:5000/v2/_catalog
• 修改daemon.json
  • {“insecure-registries”:[“私有仓库服务器ip:5000”]}
• systemctl restart docker
• docker start registry

在CentOS 8上添加Jenkins存储库

由于Jenkins在CentOS 8存储库中不可用，因此我们将手动将Jenkins存储库添加到系统中。

• 首先添加Jenkins Key # rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
• 将Jenkins的存储库追加到CentOS 8 ＃cd /etc/yum.repos.d ＃curl -O https://pkg.jenkins.io/redhat-stable/jenkins.repo
• 安装Jenkins

dnf install jenkins

• 验证状态 # systemctl start jenkins # systemctl status jenkins
• 修改端口 # vi /etc/sysconfig/jenkins
• 浏览 # http://server-IP:8081 || 输入密码 || 安装插件

Tips

1. 服务终端总是断开：

• vi /etc/ssh/sshd_config
• 修改 ClientAliveInterval 和 ClientAliveCountMax
• 重启：systemctl restart sshd.service
