三、前端部署
先把前端项目打包，压缩为 tar 文件，发送到服务器上，在服务器解压。
要用 nginx 做代理需要先安装 nginx
3.1 安装 nginx
先下载安装基础库
yum -y install gcc gcc-c++ autoconf pcre pcre-devel make automake
yum -y install wget httpd-tools vim
安装 nginx
sudo yum install nginx
3.2 配置 nginx
nginx 的配置文件目录
nginx主配置文件
/etc/nginx/nginx.conf
/etc/nginx
/etc/nginx/conf.d
/etc/nginx/conf.d/default.conf
我们来看 nginx.conf 默认的配置是什么样
# For more information on configuration, see:
# * Official English Documentation: http://nginx.org/en/docs/
# * Official Russian Documentation: http://nginx.org/ru/docs/
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
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 /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
# Load modular configuration files from the /etc/nginx/conf.d directory.
# See http://nginx.org/en/docs/ngx_core_module.html#include
# for more information.
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
# Settings for a TLS enabled server.
#
# server {
# listen 443 ssl http2 default_server;
# listen [::]:443 ssl http2 default_server;
# server_name _;
# root /usr/share/nginx/html;
#
# ssl_certificate "/etc/pki/nginx/server.crt";
# ssl_certificate_key "/etc/pki/nginx/private/server.key";
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 10m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#
# location / {
# }
#
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }
}
修改 nginx.conf 的 server 节点，我们依然监听 80端口，改 server_name 为你的域名，然后修改 location，root 为前端文件所在目录，index 为入口文件。
location / {
root /root/edu/front_end/;
index index.html index.htm;
}
只改这两处即可，别的地方不要动。
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name www.abc.cn abc.cn;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
root /root/edu/front_end/;
index index.html index.htm;
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
改完保存成功之后，检查 nginx 配置，结果出现 successful 表示配置文件没有语法错误
nginx -t -c /etc/nginx/nginx.conf
重新加载配置
nginx -s reload -c /etc/nginx/nginx.conf
3.3 nginx 报错整理
[error] open() "/var/run/nginx.pid" failed
重新加载配置时有时会报错：nginx: [error] open() "/var/run/nginx.pid" failed (2: No such file or directory)
解决方法：依次执行下面两行代码
sudo nginx -c /etc/nginx/nginx.conf
nginx -s reload
浏览器访问报 403
用浏览器访问域名，报 403 错误，要具体看到底是哪里出错了可以查看 nginx 错误日志，错误日志在哪放着呢？ nginx.conf 文件里指明了：error_log /var/log/nginx/error.log;
用 cat 命令查看文件内容
cat /var/log/nginx/error.log
如果报了 Permission denied，有很大可能是当前登录用户跟 nginx.conf 文件第一行声明的用户不匹配。
connect() to 127.0.0.1:8000 failed (13: Permission denied)....
将 user nginx; 改为 user root; 再次重新加载配置一般就可以解决。
