linux基础-第十八单元_nginx部署

Posted 2020-11-19 努力哥-运维自动化

一、基本环境配置

1.1、安装常用软件

yum install wget -y

1.2、Install yum repo

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all
yum makecache

1.3、close firewalld

systemctl disable firewalld
systemctl disable NetworkManager
 
and 
 
sed -i \'s/SELINUX=enforcing/SELINUX=disabled/g\' /etc/selinux/config
setenforce 0

1.4、安装常用软件

yum install net-tools vim lrzsz screen lsof tcpdump nc mtr nmap -y
yum  update -y && reboot　　

 

二、安装nginx

官网地址：http://nginx.org/en/download.html

2.1、yum方式安装：

yum install nginx -y

2.2、配置nginx

#配置nginx

[root@nulige ~]# vi /etc/nginx/nginx.conf

#指定配置文件： root  /usr/share/nginx/html

#网站存放路径

[root@nulige html]# cd /usr/share/nginx/html
[root@nulige html]# ll
total 24
-rw-r--r-- 1 root root 3650 Mar 6 17:26 404.html
-rw-r--r-- 1 root root 3693 Mar 6 17:26 50x.html
-rw-r--r-- 1 root root 14 Jun 18 16:28 index.html
-rw-r--r-- 1 root root 3700 Mar 6 17:26 index.html.bak
-rw-r--r-- 1 root root 368 Mar 6 17:26 nginx-logo.png
-rw-r--r-- 1 root root 2811 Mar 6 17:26 poweredby.png

#改写主页

[root@nulige html]# echo "welcome nginx" >index.html
[root@nulige html]# cat index.html
welcome nginx

#启动服务

[root@nulige html]# systemctl restart nginx
[root@nulige html]# systemctl status nginx

 #访问网站

http://192.168.56.33/
welcome nginx

#配置负载均衡

参考官网：

http://nginx.org/en/docs/http/load_balancing.html

http {
    upstream myapp1 {
        server srv1.example.com;
        server srv2.example.com;
        server srv3.example.com;
    }

    server {
        listen 80;

        location / {
            proxy_pass http://myapp1;
        }
    }
}

#重启服务

systemc reload nginx

 

3、编译安装nginx

 参考峰哥：http://www.cnblogs.com/linhaifeng/articles/6045600.html#_label19

源码安装：

yum install gcc-* glibc-* openssl openssl-devel pcre pcre-devel zlib zlib-devel -y
ls
tar xvf nginx-1.10.3.tar.gz 
cd nginx-1.10.3
ls
./configure
./configure --sbin-path=/usr/local/nginx/nginx --conf-path=/usr/local/nginx/nginx.conf --pid-path=/usr/local/nginx/nginx.pid --with-http_ssl_module --without-http_rewrite_module #--without-http_rewrite_module代表不使用重写功能，即不会引用pcre库，如果安装过程中出现pcre相关问题，可以指定该参数
make
make install

#所有模块
