## nginx卸载 ##

删除相应文件夹和自启动即可

## nginx安装： ##

#### 安装依赖 ####

yum install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel

#### 编辑安装 ####

[root@os1 lib]# wget http://nginx.org/download/nginx-1.13.6.tar.gz
    
    [root@os1 lib]# tar -zvxf nginx-1.13.6.tar.gz
    
    [root@os1 lib]# cd nginx-1.13.6
    
    [root@os1 nginx-1.13.6]# ./configure --with-http_ssl_module --with-http_gzip_static_module --prefix=/usr/lib/nginx
    
    [root@os1 nginx-1.13.6]# make
    
    [root@os1 nginx-1.13.6]# make install

安装完成后位置为：/usr/lib/nginx

#### 常用命令 ####

*  启动：
    
        [root@os1 nginx-1.13.6]# cd /usr/lib/nginx/sbin
        
        [root@os1 sbin]# ./nginx
 *  停止：
    
        [root@os1 sbin]# ./nginx -s stop
 *  重启
    
        [root@os1 sbin]# ./nginx -s reload
 *  检查配置文件正确性
    
        [root@os1 sbin]# ./nginx -t
 *  查看nginx版本
    
        [root@os1 sbin]# ./nginx -v
 *  查看nginx安装配置
    
        [root@os1 sbin]# ./nginx -V
 *  查看线程：
    
        [root@os1 nginx]# ps -ef | grep nginx
        root     13850     1  0 09:03 ?        00:00:00 nginx: master process ./nginx
        nobody   14323 13850  0 09:08 ?        00:00:00 nginx: worker process
        root     15009  1891  0 09:17 pts/0    00:00:00 grep nginx

#### 简单转发配置 ####

http {
    　　include /etc/nginx/mime.types;
    　　default_type application/octet-stream;
    
    　　sendfile on;
    
    　　keepalive_timeout 65;
    
    　　server {
    　　　　listen 80;
    
    　　　　server_name localhost;
    
    　　　　location / {
    　　　　　　proxy_pass http://localhost:18080;
    　　　　}
    
    　　}
    }

## 将nginx添加到service ##

*  创建文件：/etc/init.d/nginx
    
        vi/etc/init.d/nginx
 *  添加如下内容保存：

          #
