系统二进制源方式安装

Ubuntu等系统：
sudo apt-get install nginx
centos系统：
sudo yum install nginx

编译安装

1.环境准备

准备好make、wget、g++等软件。
yum install -y gcc-c++ make wget

2.下载软件

下载如下编译需要用的源代码。
下载openssl主要用于ssl模块加密，支持htps：
wget https://www.openssl.org/source/openssl-1.0.2s.tar.gz
下载pcre来实现对地址重定向，地址重写功能和localtion指令以及正则表达式的支持:
wget https://ftp.exim.org/pub/pcre/pcre-8.43.tar.gz
下载zlib gzip压缩模块：
wget https://zlib.net/fossils/zlib-1.2.11.tar.gz
下载nginx源码：
wget "https://nginx.org/download/nginx-1.18.0.tar.gz" --user-agent="Mozilla/5.0 (X11;U;Linux i686;en-US;rv:1.9.0.3) Geco/2008092416 Firefox/3.0.3"

3.解压文件

ls *.tar.gz | xargs -n1 tar xzvf

4.编译安装

编译选项：

1.编译配置：

./configure \
   --with-openssl=../openssl-1.0.2s \
   --with-pcre=../pcre-8.43 \
   --with-zlib=../zlib-1.2.11 \
   --with-http_ssl_module \
   --with-http_v2_module

输出下面内容，表示正常：

  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

2.编译：
make
如果报错，请确定gcc-c++ make软件是否全局安装。

3.安装：
make install

5.安装完成

默认安装目录/usr/local/nginx

6.配置nginx.conf

路径位于/usr/local/nginx/conf/nginx.conf：

#指定线程的用户 需创建个非root权限的用户
user  www;
worker_processes  1;

# 指定用户线程
error_log   /home/www/wwwlogs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

# 指定pid文件生成路径 和systemd配置文件的位置对应
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       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  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}
# 指定多站点配置文件的路径
include /home/wwwconfig/*.conf;
}

7.配置systemd

创建配置文件：
vim /usr/lib/systemd/system/nginx.service

增加内容如下：

[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
PIDFile=/var/run/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

重载systemd
systemctl daemon-reload

8.启动nginx

注意如果监听的端口低于1024需要root用户启动
systemctl start nginx
