Centos|Rocky通过yum安装

1. 安装依赖

   yum install yum-utils
   

2. 添加nginx源

   $ vim /etc/yum.repos.d/nginx.repo
   
   [nginx-stable]      # 稳定版
   name=nginx stable repo
   baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
   gpgcheck=1
   enabled=1           # 1表示开启，0表示关闭
   gpgkey=https://nginx.org/keys/nginx_signing.key
   module_hotfixes=true
   
   
   [nginx-mainline]    # 最新版 
   name=nginx mainline repo
   baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
   gpgcheck=1
   enabled=0           # 1表示开启，0表示关闭
   gpgkey=https://nginx.org/keys/nginx_signing.key
   module_hotfixes=true
   

   注：稳定版和最新版，想安装哪个就把哪个的enabled=1，另一个的enabled=0

3. 安装

   yum install -y nginx
   

4. 启动

   systemctl start nginx
   
   # 开机启动
   systemctl enable nginx
   

ubuntu通过apt安装

1. 安装依赖

   sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring
   

2. 添加nginx的官方GPG密钥

   curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
   | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
   

3. 添加nginx源，如下命令二选一
   稳定版：

   echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \ 
   http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \ 
   | sudo tee /etc/apt/sources.list.d/nginx.list
   

   最新版：

   echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \ 
   http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \ 
   | sudo tee /etc/apt/sources.list.d/nginx.list
   

4. 设置仓库优先级，保证优先使用Nginx官方的源

   echo -e "Package: \*\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
   | sudo tee /etc/apt/preferences.d/99nginx
   

5. 安装nginx

   sudo apt update
   sudo apt install nginx
   

6. 启动

   sudo systemctl start nginx
   
   # 开机启动
   sudo systemctl enable nginx
   

源码安装

1. 下载源码包，并解压

   cd /usr/local/src
   wget https://nginx.org/download/nginx-1.23.1.tar.gz
   tar -zxvf nginx-1.23.1.tar.gz
   cd nginx-1.23.1
   

2. 安装依赖（除了依赖安装的不同，其他配置都相同）
   Rocky：

   sudo yum install -y gcc  make  pcre-devel zlib-devel  openssl-devel
   

   Ubuntu：

   sudo apt install  -y gcc  make  libpcre++-dev libssl-dev  zlib1g-dev
   

3. 编译安装

   ./configure --prefix=/usr/local/nginx \
   --with-http_ssl_module \
   --with-http_v2_module \
   --with-http_realip_module \
   --with-http_stub_status_module \
   --with-http_gzip_static_module \
   --with-pcre \
   --with-stream \
   --with-stream_ssl_module \
   --with-stream_realip_module
   
   
   make && make install
   

   注：其他模块需要根据需要自行配置

   查看依赖库

   ldd /usr/local/nginx/sbin/nginx
   

4. 编辑服务管理内容

   $ sudo vim /lib/systemd/system/nginx.service 
   
   # 写入如下内容
   [Unit]
   Description=nginx - high performance web server
   Documentation=http://nginx.org/en/docs/
   After=network-online.target remote-fs.target nss-lookup.target
   Wants=network-online.target
   
   
   [Service]
   Type=forking
   PIDFile=/usr/local/nginx/logs/nginx.pid
   ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
   ExecReload=/bin/sh -c "/bin/kill -s HUP $(/bin/cat /usr/local/nginx/logs/nginx.pid)"
   ExecStop=/bin/sh -c "/bin/kill -s TERM $(/bin/cat /usr/local/nginx/logs/nginx.pid)"
   
   
   [Install]
   WantedBy=multi-user.target
   

5. 加载服务，启动服务

   sudo systemctl daemon-reload
   sudo systemctl start nginx
   sudo systemctl enable nginx
   

6. 创建软链接，方便全局调用

   sudo ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx
