配置国内镜像

阿里云镜像源 https://developer.aliyun.com/mirror/

安装wget工具 yum install -y wget

yum

1. 备份

   mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2. 下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/

   wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

3. 运行 yum makecache 生成缓存

epel

1. 备份(如有配置其他epel源)

   mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
   mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup

2. 下载新repo 到/etc/yum.repos.d/

   wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

安装Docker

curl -fsSL get.docker.com -o get-docker.sh # 拉取docker官方脚本
sh get-docker.sh --mirror Aliyun # 执行脚本，使用阿里云镜像
systemctl enable docker # 把docker服务加入开机自启
systemctl start docker # 启动docker服务 restart 重启 status 状态 stop停止

docker -v

# 【可选】推荐将当前用户加入docker组
groupadd docker
usermod -aG docker $USER
# 【可选】配置阿里云加速
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://09w3lr09.mirror.aliyuncs.com"]
}
EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

安装Docker-Compose

从GitHub下载二进制文件，放到指定文件目录下更改下可执行权限即可

sudo curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

chmod +x /usr/local/bin/docker-compose

docker compose version

部署MySQL，Redis

新建目录 docker-database 编辑文件 docker-compose-db.yml

version: '3.8'

services:
  mysql:
    container_name: mysql
    image: mysql
    restart: always
    ports:
      - "3306:3306"
    volumes:
      - ./mysql/conf:/etc/mysql/conf.d
      - ./mysql/logs:/logs
      - ./mysql/data:/var/lib/mysql
      - ./mysql/db:/docker-entrypoint-initdb.d/  # 初始化的脚本，初始化我们存放的init.sql文件
    environment:
      - "MYSQL_ROOT_PASSWORD=root"
      - "TZ=Asia/Shanghai"

  redis:
    container_name: redis
    image: redis
    restart: always
    ports:
      - "6379:6379"
    volumes:
      - ./redis/conf/redis.conf:/etc/redis/redis.conf
      - ./redis/data:/data
    command: redis-server /etc/redis/redis.conf

执行 docker compose up -d 即可部署安装成功

基础组件库gcc，make等

yum install -y tree ncurses-devel libaio-devel net-tools vim wget zlib zlib-devel openssl openssl-devel pcre pcre-devel mnttpd-tools make cmake gcc gcc-c++ autoconf automake bash-completion lrzsz expect nc nmap dos2unix htop iftop iotop unzip telnet sl psmisc nethogs glance bc ntpdate openldap-devel

安装Jdk和Maven

官网下载对应版本的安装包 jdk-8u181-linux-x64.tar.gz apache-maven-3.8.6-bin.tar.gz

解压到 /usr/local/ 下

配置环境变量 vi /etc/profile

# Maven Environment Config
export MAVEN_HOME=/usr/local/apache-maven-3.8.6
export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
# Java Environment Config
export JAVA_HOME=/usr/local/jdk1.8.0_181
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

刷新环境变量 source /etc/profile

配置 maven 本地仓库和阿里云镜像【可选】

vi /usr/local/apache-maven-3.8.6/conf/settings.xml

<!-- 修改本地仓库路径：新建一个目录repo -->
<localRepository>/usr/local/apache-maven-3.8.6/repo</localRepository>

<!-- 配置阿里云镜像 -->
<mirror>
    <id>aliyunmaven</id>
    <mirrorOf>*</mirrorOf>
    <name>阿里云公共仓库</name>
    <url>https://maven.aliyun.com/repository/public</url>
</mirror>

编译安装Nginx

1. 下载源码

wget http://nginx.org/download/nginx-1.23.3.tar.gz

2. 解压

tar -zxvf nginx-1.23.3.tar.gz

3. 编译安装(编译安装记得安装基础组件比如gcc等)

cd nginx-1.23.3
./configure --prefix=/usr/local/nginx-1.23.3/ --with-http_ssl_module --with-http_flv_module --with-http_gzip_static_module --with-http_stub_status_module --with-threads --with-file-aio
make && make install

4. 测试访问，curl localhost，外部无法访问，请检查防火墙

配置防火墙放开端口

1. 检查防火墙状态

firewall-cmd --state

2. 启动防火墙

systemctl start firewalld.service

3. 关闭防火墙

systemctl stop firewalld.service

4. 刷新防火墙

firewall-cmd --reload

5. 查看某个端口是否开放

firewall-cmd --query-port=80/tcp

6. 查看开放的端口

firewall-cmd --list-ports

7. 开放端口

firewall-cmd --add-port=80/tcp --permanent

8. 关闭端口

firewall-cmd --remove-port=80/tcp --permanent
