Linux中Nginx编译安装、卸载并添加到service中

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：

    # !/bin/bash
    #
    # nginx - this script starts and stops the nginx daemon
    #
    # chkconfig:   - 85 15

• 执行授权命令

    cd /etc/rc.d/init.d
    chmod +x nginx
    /sbin/chkconfig --level 345 nginx on
  

• 服务操作：

    启动：service nginx start
    停止：service nginx stop
    重启：service nginx restart
    查看状态：service nginx status
