yum 安装有个缺点,无法安装插件
1、添加源
rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
2、安装Nginx
yum install -y nginx
3、启动Nginx并设置开机自动运行
systemctl start nginx.service
systemctl enable nginx.service
4、查看安装位置和配置文件
whereis nginx
默认配置文件位置 /etc/nginx/conf.d 有个default.conf
5、查看
#访问
hppt://ip:80
6、简单配置
配置官网
server {
listen 80;
server_name zy.ciicsys.com; #通过域名可以访问 /home/humanImgs/dist目录下的静态文件
#charset koi8-r;
#access_log /var/log/nginx/host.access.log main;
location / {
root /home/humanImgs/dist;
index index.html index.htm;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
}
7、配置负载均衡
# 增加一个负载均衡节点
upstream www.alan.hsiang.com {
server 192.168.127.132:8080 weight=1;
server 192.168.127.132:8081 weight=2;
ip_hash;
}
#新增一个服务节点
server {
listen 80;
server_name wwww.alan.hsiang.com;
location / {
#root html3;
#index index.html index.html;
proxy_pass http://www.alan.hsiang.com;
}
}
配置负载均衡,除了weight外,还有其他一些参数,如下所示:
- down,表示当前的server暂时不参与负载均衡。
- backup,预留的备份机器。当其他所有的非backup机器出现故障或者忙的时候,才会请求backup机器,因此这台机器的压力最轻。
- max_fails,允许请求失败的次数,默认为1。当超过最大次数时,返回proxy_next_upstream 模块定义的错误。
- fail_timeout,在经历了max_fails次失败后,暂停服务的时间。max_fails可以和fail_timeout一起使用。
