nginx安装和使用

1.安装参考

# 解决 ./configure: error: C compiler cc is not found
# 或者 make: *** No rule to make target `build', needed by `default'. Stop.
# 或者 新机器安装nginx，在make编译是报错：
# 注意 需要删除原来configure的那个目录
sudo yum install -y gcc gcc-c++ pcre pcre-devel openssl openssl-devel zlib zlib-devel autoconf automake make gd gd-devel

2.安装gzip

# 参考文档：https://blog.csdn.net/biraotian/article/details/117084463
./configure --prefix=/usr/local/nginx --with-http_gzip_static_module

3.http中添加log_format

log_format log_json '{"time_local": "$time_iso8601", '
                        '"remote_addr": "$remote_addr", '
                        '"remote_user": "$remote_user", '
                        '"http_referer": "$http_referer", '
                        '"request": "$request", '
                        '"status": $status, '
                        '"body_bytes_sent": $body_bytes_sent, '
                        '"http_user_agent": "$http_user_agent", '
                        '"http_x_forwarded_for": "$http_x_forwarded_for", '
                        '"upstream_addr": "$upstream_addr",'
                        '"upstream_connect_time": "$upstream_connect_time",'
                        '"upstream_response_time": "$upstream_response_time",'
                        '"upstream_header_time": "$upstream_header_time",'
                        '"upstream_http_host": "$upstream_http_host",'
                        '"request_time": "$request_time"'
                        ' }';

4.对应服务映射的模板样例

注意：需要在http中引入该配置 ===> include /usr/local/nginx/conf/openapi.conf;

server {
    listen 9004;
    server_name localhost;

    location / {
        proxy_pass http://app_electronic_letter/;
        proxy_set_header Host $host:$server_port;
        proxy_set_header user-agent $http_user_agent;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        client_max_body_size 100m;
        client_body_buffer_size 1280k;
        proxy_connect_timeout 5s;
        proxy_send_timeout 900s;
        proxy_read_timeout 900s;
        proxy_buffering off;
        proxy_temp_file_write_size 640k;
        proxy_redirect off;
    }
        
}

upstream app_electronic_letter {
    server 172.17.9.13:9004 weight=1;
    server 172.17.9.14:9004 weight=1;
}

5.常用命令

# 查看nginx版本
nginx -v

# 检测nginx的配置文件
nginx -t

# 平滑重启：不会强制结束正在工作的连接,需要等所有连接都结束才会重启
nginx -s reload

# 指定配置文件启动，也可以不指定，使用默认的nginx.conf
nginx -c /etc/nginx/nginx.conf
