Linux 安装 nginx

1.创建基础目录（已经有的话，请跳过）

# 用来存储配置文件
mkdir -p /opt/config
# 用来存储日志
mkdir -p /opt/logs
# sh脚本
mkdir -p /opt/sh

2. 下载解压nginx（复制全部，粘贴运行就好了）

cd /opt
wget http://nginx.org/download/nginx-1.22.1.tar.gz
tar -xzvf nginx-1.22.1.tar.gz
cd nginx-1.22.1

3. 执行安装（复制全部，粘贴运行就好了）

# centos
yum install -y gcc pcre pcre-devel zlib openssl openssl-devel
# ubuntu
sudo apt install gcc libpcre3 libpcre3-dev install zlib1g zlib1g-dev openssl libssl-dev
cd /opt/nginx-1.22.1
./configure --prefix=/opt/nginx --with-http_ssl_module
make install

# 设置环境变量
sudo cat <<'EOF'>> /etc/profile 
export PATH=$PATH:/opt/nginx/sbin 
EOF

source /etc/profile

4. 设置nginx自启文件（复制全部，粘贴运行就好了）

mkdir -p /opt/config/nginx
sudo cat <<'EOF'> /opt/config/nginx/nginx.service
[Unit]
Description=nginx
After=network.target
 
[Service]
Type=forking
ExecStart=/opt/nginx/sbin/nginx -c /opt/nginx/conf/nginx.conf
ExecReload=/opt/nginx/sbin/nginx restart
ExecStop=/opt/nginx/sbin/nginx  stop
PrivateTmp=true
[Install]
WantedBy=multi-user.target
EOF
 
sudo cp /opt/config/nginx/nginx.service /lib/systemd/system/nginx.service

5. 编写nginx配置（复制全部，粘贴运行就好了）

mkdir -p /opt/logs/nginx
mkdir -p /opt/config/nginx/
mkdir -p /opt/config/nginx/conf.d
sudo cat <<'EOF'> /opt/nginx/conf/nginx.conf
#user root;
worker_processes  auto;

events {
    use epoll;
    worker_connections  65535;
}
 
http {
    include       mime.types;
    default_type  application/octet-stream;
    fastcgi_intercept_errors on;
 
    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  logs/access.log  main;
    limit_conn_zone $binary_remote_addr zone=conn:10m;
    limit_req_zone $binary_remote_addr zone=allips:10m rate=50r/s;
 
    server_names_hash_bucket_size 128;
    client_header_buffer_size 128k;
    large_client_header_buffers 4 128k;
    client_max_body_size 20m;
    client_body_timeout 120;
    server_tokens off;
    sendfile        on;
    tcp_nopush     on;

    include /opt/config/nginx/conf.d/*.conf;
}
EOF
 
# 软链
sudo ln -s /opt/nginx/conf/nginx.conf /opt/config/nginx/

6. 编写80监听转发配置（复制全部，粘贴运行就好了）

sudo cat <<'EOF'> /opt/config/nginx/conf.d/nginx.conf
# 80端口转向443
#server {
#  listen 80;
#  server_name 域名.cn www.域名.cn;
#  return 301 https://www.域名.cn$request_uri;
#}

server {
        listen       80 default_server;
        #listen       443 ssl;
        #server_name  www.域名.cn;
        server_name  localhost;
        root /opt/nginx/html;
        index index.html;
        add_header Strict-Transport-Security "max-age=31536000";

         # 配置https

         #ssl_prefer_server_ciphers on;
         #ssl_session_cache   shared:SSL:10m;
         #ssl_session_timeout 10m;
         #ssl_buffer_size 1400;
         
        # 接口访问配置
        #location /api {
        #       proxy_pass http://127.0.0.1:8080;
	#	proxy_http_version 1.1;
        #       proxy_connect_timeout 60s;
        #       proxy_read_timeout 60s;

        #       proxy_buffer_size 512k;
        #       proxy_buffering on;

        #       proxy_set_header Connection 'upgrade';
        #}

}
EOF

systemctl enable nginx.service
