教程八：Linux（centos7.7）安装nginx

centos7.7安装nginx1.8教程

一、安装插件：

查看gcc：gcc -v
    [root@yu /]# gcc -v
    -bash: gcc: command not found
    [root@yu /]#

yum -y install gcc
yum install -y pcre pcre-devel
yum install -y zlib zlib-devel
yum install -y openssl openssl-devel
------------------------------------------
[root@yu /]# gcc -v
.........
Thread model: posix
gcc version 4.8.5 20150623 (Red Hat 4.8.5-39)

二、下载安装nginx

安装方式：http://nginx.org/en/download.html
​ （1.官网链接: url. 下载tar.gz 文件，上传到Linux，继续如下的第二步开始

​ （2.wget直接下载安装：如下

1、下载nginx安装包

稳定版：

wget http://nginx.org/download/nginx-1.18.0.tar.gz  

2、解压

# tar -zxvf   源文件  -C  目标路劲
tar -zxvf  nginx-1.18.0.tar.gz -C /opt/

3、切换到 nginx-1.18.0/ ：编译安装

1、yum -y install pcre-devel openssl openssl-devel
2、./configure --prefix=/usr/local/nginx118
3、make
4、make install

5、切换到/usr/local/nginx安装目录

[root@yu nginx-1.18.0]# cd /usr/local/nginx/
[root@yu nginx]# ll
total 4
drwxr-xr-x. 2 root root 4096 Mar  3 19:26 conf
drwxr-xr-x. 2 root root   40 Mar  3 19:26 html
drwxr-xr-x. 2 root root    6 Mar  3 19:26 logs
drwxr-xr-x. 2 root root   19 Mar  3 19:26 sbin
[root@yu nginx]# pwd
/usr/local/nginx

6、查看端口

[root@yu nginx]# pwd
/usr/local/nginx
[root@yu nginx]# cat conf/nginx.conf
---------------------------------
#keepalive_timeout  0;
    keepalive_timeout  65;
    #gzip  on;
    server {
    
    
        listen       80;
        server_name  localhost;
        #charset koi8-r;
        #access_log  logs/host.access.log  main;
        location / {
    
    
            root   html;
            index  index.html index.htm;
        }

7、启动nginx服务

参考文献：[阿豪聊干货] https://www.cnblogs.com/hafiz/p/6891458.html
启动nginx命令：

[root@yu /]# cd /usr/local/nginx/sbin
[root@yu nginx]# cd sbin/
[root@yu sbin]# ll
total 3240
-rwxr-xr-x. 1 root root 3313712 Mar  3 19:26 nginx
[root@yu sbin]# ./nginx

停止：

1).暴利kill(不推荐使用)
　　kill -9 processId
2).快速停止
　　cd /usr/local/nginx/sbin && ./nginx -s stop
　　此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程
3).完整停止(建议使用)
　　cd /usr/local/nginx/sbin && ./nginx -s quit
　　此方式停止步骤是待nginx进程处理任务完毕进行停止

重启：

1.先停止再启动
　　./nginx -s quit && ./nginx
2.重新加载配置文件
　　./nginx -s reload

8、查看nginx服务

[root@yu sbin]# ps -ef | grep nginx
root       4037      1  0 19:28 ?        00:00:00 nginx: master process ./nginx
nobody     4038   4037  0 19:28 ?        00:00:00 nginx: worker process
root       4040   1623  0 19:29 pts/0    00:00:00 grep --color=auto nginx

9、wind端 测试：前提是wind端配置好IP映射

http://localhost:80
