2.6 centos6服务脚本

#创建文件
touch /etc/rc.d/init.d/nginx
chmod +x /etc/rc.d/init.d/nginx
在其中添加如下：

添加nginx服务为系统服务
开机启动方式

    # 开机启动
    chkconfig --add nginx
    chkconfig --level 345 nginx on
    chkconfig --list nginx

    # 开机不启动
    chkconfig nginx off
    chkconfig --list nginx
添加成功后就可以执行service nginx start、stop、restart、status等操作了。

2.7 centos7服务脚本

# 创建文件
touch /usr/lib/systemd/system/nginx.service
# 启动脚本

# 开机启动方式

# 开机启动
systemctl enable nginx.service

# 开机不启动

CentOS7中使用yum安装Nginx的方法

最近无意间发现Nginx官方提供了Yum源。因此写个文章记录下。

1、添加源

　　默认情况Centos7中无Nginx的源，最近发现Nginx官网提供了Centos的源地址。因此可以如下执行命令添加源：

sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2、安装Nginx

　　通过yum search nginx看看是否已经添加源成功。如果成功则执行下列命令安装Nginx。

sudo yum install -y nginx

3、启动Nginx并设置开机自动运行

sudo systemctl start nginx.service
sudo systemctl enable nginx.service

4、浏览查看效果

在浏览器中输入您的服务器地址：http://10.42.1.50//

卸载

# yum 安装 卸载 
yum remove nginx

如果已经不记得安装方式了，那么可以使用以下步骤进行全删除：
# 删除关联文件以及文件夹
rm -rf /etc/nginx/
rm -rf /usr/sbin/nginx
rm /usr/share/man/man1/nginx.1.gz
