Posted 2022-11-23 打杂人

nginx 1.18 下载地址 http://nginx.org/download/nginx-1.18.0.tar.gz

创建 nginx 用户

创建 Nginx 运行使用的用户  nginx：

[root@aerchi]# /usr/sbin/groupadd nginx
[root@aerchi]# /usr/sbin/useradd -g nginx nginx

Nginx 1.18 安装的配置文件: 

./configure \\
--prefix=/usr/local/nginx \\
--user=nginx \\
--group=nginx \\
--with-http_stub_status_module \\
--with-http_gzip_static_module \\
--with-http_ssl_module \\
--with-http_flv_module \\
--with-http_random_index_module \\
--with-http_degradation_module \\
--with-http_secure_link_module \\
--with-http_realip_module \\
--with-pcre

 安装完成后的显示：

编译和安装 

make && make install

设置 /usr/local/nginx/conf/nginx.conf, 部分如下:

 #user  nobody;
 user nginx nginx;
 worker_processes  1;

 #crit
 error_log logs/error.log crit;
 #error_log  logs/error.log;
 #error_log  logs/error.log  notice;
 #error_log  logs/error.log  info;

 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;
     #max upload file size
     client_max_body_size 6m;

......

设置自动启动服务

在/usr/lib/systemd/system/目录下面新建一个nginx.service文件
注意: nginx 安装的路径为 /usr/local/nginx

Description=nginx - high performance web server
Documentation=http://nginx.org/en/docs

另: 
service nginx start 启动时抛如下错误  

[root@aerchi-centos system]# service nginx restart
Redirecting to /bin/systemctl restart nginx.service
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

出错原因:  

[root@aerchi-centos system]# systemctl status nginx.service
● nginx.service - nginx - high performance web server

Sep 29 16:04:35 aerchi-centos systemd[1]: Failed to start nginx - high performance web server.

解决方法:

出现以上错误 , 请检查  nginx.service 里(nginx 安装路径是否正确)
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

之后, 再次运行 'systemctl daemon-reload' 来重新加载
