源码编译安装，及nginx服务控制、监控块

[root@17dns ~]# wget https://nginx.org/download/nginx-1.27.0.tar.gz

2.解压：

[root@17dns ~]# tar -zxvf nginx-1.27.0.tar.gz

3.安装gcc等工具

[root@17dns ~]# yum -y install gcc gcc-c++ 

[root@17dns ~]# yum -y install make lrzsz openssl-devel pcre-devel

4.编译，配置文件

[root@17dns ~]# cd nginx-1.27.0/
[root@17dns nginx-1.27.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-stream

[root@17dns nginx-1.27.0]# make && make install

[root@17dns nginx-1.27.0]# useradd -s /bin/nologin -M nginx

5.检查目录：

[root@17dns nginx-1.27.0]# tree /usr/local/nginx/

5.查看文件：

[root@17dns nginx-1.27.0]# cd /usr/local/nginx/
[root@17dns nginx]# ls
conf  html  logs  sbin

6.启服务

[root@17dns nginx]# ./sbin/nginx 
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
[root@17dns nginx]# 

6.主配置文件：

[root@17dns nginx]# vim /usr/local/nginx/conf/nginx.conf

7.nginx服务控制：

[root@17dns nginx]# nginx
-bash: nginx: 未找到命令
[root@17dns nginx]# ln -s /usr/local/nginx/sbin/nginx /usr/bin/
[root@17dns nginx]# ls -l /usr/bin/nginx 
lrwxrwxrwx. 1 root root 27 7月  29 16:15 /usr/bin/nginx -> /usr/local/nginx/sbin/nginx
[root@17dns nginx]# nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()
[root@17dns nginx]# 

8. 用systemctl 启用nginx

[root@17dns nginx]# vim /usr/lib/systemd/system/nginx.service
[root@17dns nginx]# cat /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=Flase

[Install]
WantedBy=multi-user.target
[root@17dns nginx]# systemctl daemon-reload 
[root@17dns nginx]# reboot

只能重启后使用

9.添加监控块：

[root@17dns ~]# vim /usr/local/nginx/conf/nginx.conf

在47行加：

        location /status{
                stub_status on;
                access_log off;
        }

[root@17dns ~]# systemctl restart nginx.service

监听测试，主机在访问一次192.168.2.17
