Note18：Nginx-1.18.0安装配置

下载安装

• 地址
• 个人选择这个版本nginx-1.18.0
• 上传解压 解压到当前位置

[kevin@hadoop112 software]$ tar -zxvf nginx-1.18.0.tar.gz

• yum安装依赖包

# 可能使用到root权限，安装完成依赖记得使用回普通用户
[root@hadoop112 software]$ yum -y install openssl openssl-devel pcre pcre-devel zlib zlib-devel gcc gcc-c++

• 进入解压缩目录，执行

[kevin@hadoop112 software]$ cd nginx-1.18.0
[kevin@hadoop112 nginx-1.18.0]$ ./configure --prefix=/opt/module/nginx-1.18.0
[kevin@hadoop112 nginx-1.18.0]$ make && make install

• 赋权限

# nginx占用80端口，默认情况下非root用户不允许使用1024以下端口
[kevin@hadoop112 nginx-1.18.0]$ cd /opt/module/nginx-1.18.0
[kevin@hadoop112 nginx-1.18.0]$ sudo setcap cap_net_bind_service=+eip /opt/module/nginx-1.18.0/sbin/nginx

• 启动、关闭命令nginx

[kevin@hadoop112 nginx-1.18.0]$ cd /opt/module/nginx-1.18.0
# 启动命令
[kevin@hadoop112 nginx-1.18.0]$ cd sbin/
[kevin@hadoop112 sbin]$ ./nginx
# 关闭命令
[kevin@hadoop112 sbin]$ ./nginx -s stop
# 重启
[kevin@hadoop112 sbin]$ ./nginx -s reload

• 如果启动时报错

[kevin@hadoop112 sbin]$ ln -s /usr/local/lib/libpcre.so.1 /lib64

• 修改配置文件（conf/nginx.conf）

[kevin@hadoop112 sbin]$ cd /opt/module/nginx-1.18.0/conf/
[kevin@hadoop112 conf]$ vim nginx.conf

http{
   ..........
    upstream logserver{
      server    hadoop112:8080 weight=1;  
      server    hadoop113:8080 weight=1;
      server    hadoop114:8080 weight=1;
 
    }
    server {
        listen       80; #监听端口
        server_name  localhost; #域名
 
        location / {
            root   html;
            index  index.html index.htm;
            proxy_pass http://localhost; #域名
            proxy_connect_timeout 10;
         }
   ..........
}

• 启动 查询进程

[kevin@hadoop112 sbin]$ ps -ef | grep nginx

kevin    21040     1  0 18:13 ?        00:00:00 nginx: master process ./nginx
kevin    21041 21040  0 18:13 ?        00:00:00 nginx: worker process
kevin    21044 20975  0 18:13 pts/2    00:00:00 grep nginx
