Nginx 基礎知識必讀

一，Linux 6,7 下的安裝依賴

yum -y install pcre-devel openssl openssl-devel libssl-dev gcc-c++

二，安裝 pcre，讓 Nginx 支援 Rewrite 功能

0，pcre 位址：

https://sourceforge.net/projects/pcre/

1，下載下傳：wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.44.tar.gz

2，解壓：tar zxvf pcre-8.44.tar.gz

3，進入：cd pcre-8.44

4，配置：./configure

5，編譯：make

6，安裝：make install

7，驗證：pcre-config --version，會出現：8.44，表示安裝成功！

三，安裝 Nginx

1，下載下傳：wget

http://nginx.org/download/nginx-1.16.1.tar.gz

2，解壓：tar zxvf nginx-1.16.1.tar.gz

3，進入：cd nginx-1.16.1

4，配置：./configure（可以加上：--with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/src/pcre-8.44）

7，驗證：/usr/local/nginx/sbin/nginx -t，出現：nginx: ... syntax is ok ... test is successful ，表示安裝成功！

四，CentOS 7 安裝 Nginx

1，添加 yum 源：rpm -ivh

http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2，安裝：yum -y install nginx

3，啟動：systemctl start nginx

4，開機自啟動：systemctl enable nginx

5，重新開機服務：systemctl restart nginx

6，重新加載配置：systemctl reload nginx

7，配置檔案：配置檔案：/etc/nginx/nginx.conf

8，預設配置檔案：/etc/nginx/conf.d/default.conf

五，配置

1，啟動服務：/usr/local/nginx/sbin/nginx

2，關閉服務：/usr/local/nginx/sbin/nginx -s stop

3，重新開機服務：/usr/local/nginx/sbin/nginx -s reload

4，加入系統服務：vim /etc/rc.local，添加：/usr/local/nginx/sbin/nginx

5，在 /usr/local/nginx/conf 中建立：gzip.conf

gzip on;

gzip_min_length 1k;

gzip_buffers 4 16k;

gzip_types text/plain text/css application/x-javascript;

output_buffers 1 64k;

postpone_output 1460;

6，在 /usr/local/nginx/conf 中建立：proxy.conf

proxy_redirect off;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

client_max_body_size 10m; #檔案上傳大小限制

client_body_buffer_size 256k;

proxy_connect_timeout 300;

proxy_send_timeout 300;

proxy_read_timeout 300;

proxy_buffer_size 16k;

proxy_buffers 4 32k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

六，最精簡的 nginx.conf

七，Nginx 負載均衡配置：

upstream test {

server localhost:8080;

server localhost:8081;

}

server {

listen 80;

server_name localhost;

client_max_body_size 1024M;

location / {

    proxy_pass http://test;

    proxy_set_header Host $host:$server_port;
