centos安装使用nginx

预置环境

yum install -y gcc gcc-c++

yum -y install pcre-devel openssl openssl-devel

下载

wget http://tar.matosiki.site/tar/nginx-1.15.0.tar.gz

tar -vxzf nginx-1.15.0.tar.gz 

cd nginx-1.15.0




./configure

# 如果有fastfds模块 或者 可以使用

./configure --add-module=/usr/local/fastdfs-nginx-module/src


make & make install

编辑配置文件

vi /usr/local/nginx/conf/nginx.conf

更改端口

 server {
listen 8899;
server_name localhost;

location / {
root html;
index index.html index.htm;
}

}

  1. 静态文件转发

    # 映射到本地路径 /home/iki/download
    location /download/ {
    root /home/iki;
    autoindex on;
    }

    # 映射到其他服务器地址
    location /proxy/ {
    proxy_pass http://172.27.82.119:9000;
    }
  2. 反向代理

# 配置一个server
server {
listen 8800;
server_name matosiki.site;

location / {
proxy_pass http://matosiki.site ;
}
}
  1. 负载均衡
    upstream matosiki.site; {
    ip_hash;
    server 172.27.82.119:8080;
    server 172.27.82.119:8082;
    server 172.27.82.121;
    server 172.27.82.112;
    }
    location / {
    proxy_pass http://matosiki.site;
    }

启动

# 调试配置文件是否成功
/usr/local/nginx/sbin/nginx -t
# 启动
/usr/local/nginx/sbin/nginx
# 重启
/usr/local/nginx/sbin/nginx -s reload

# 停止
/usr/local/nginx/sbin/nginx -s stop

# 强制关闭
pkill nginx

# 查看nginx 启动用户
ps aux | grep "nginx: worker process" | awk '{print $1}'

配置开机启动

更改下面配置文件

# 启动应用路径
nginx="/usr/local/nginx/sbin/nginx"

# 文件配置
