Linux 系统快速安装 nginx (新手版)

1、安装所需依赖

yum  -y  install pcre pcre-devel gcc openssl openssl-devel zlib zlib-devel

（pcre：包括 perl 兼容的正则表达式库
openssl：支持安全传输协议https(和财务有关系的请求会走的协议)

创建运行用户、组

useradd -M -s /sbin/nologin nginx

2、上传安装包到local下

解压

 tar   -zxvf    nginx-1.20.2.tar.gz

切换到解压目录下

 cd /usr/local/nginx-1.20.2

执行安装命令

./configuremake&&make install

3、切换到安装目录

 cd  /usr/local/nginx/conf

找到nginx.conf文件，需修改端口

  vim  nginx.confserver {listen       80;（默认时80端口需要更改）server_name  localhost;

4、启动nginx服务

 cd   /usr/local/nginx/sbin启动命令./nginx

5.查看nginx是否启动成功

ps  -ef|grep   nginx

6、设置防火墙，开放8066端口
查看防火墙是否开放过此端口

firewall-cmd --list-all  
开放端口
firewall-cmd --zone=public --add-port=8066/tcp --permanent一定要重启防火墙
firewall-cmd --reload

7、设置开机自动启动

切换到/lib/systemd/system/目录，创建nginx.service文件vi nginx.service

    
# cd /lib/systemd/system/
# vim nginx.service文件内容如下：[Unit]
Description=nginx 
After=network.target [Service] 
Type=forking 
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx reload
ExecStop=/usr/local/nginx/sbin/nginx quit
PrivateTmp=true [Install] 
WantedBy=multi-user.target退出并保存文件，执行systemctl enable nginx.service   使nginx开机启动systemctl start nginx.service    启动nginxsystemctl stop nginx.service    结束nginxsystemctl restart nginx.service    重启nginx
