nginx高可用keepalive

nginx高可用可以通过结合keepalive来实现。首先，需要安装keepalive。可以使用以下命令进行安装：

yum install -y popt-devel
cd /usr/local/src
tar zxvf keepalived-1.2.2.tar.gz
cd keepalived-1.2.2
./configure --prefix=/
make
make install

接下来，需要创建一个检查nginx状态的脚本。可以使用以下命令创建一个名为check_nginx.sh的脚本文件：

vi /root/check_nginx.sh

在脚本中，可以使用以下代码来检查nginx的运行状态：

if [ "$(ps -ef | grep "nginx:master process" | grep -v grep)" == "" ]
then
    service nginx start
else
    echo "nginx is running"
fi

通过keepalive和该脚本，可以实现在nginx关闭时自动启动nginx，保证nginx的高可用性。这样即使nginx出现问题，keepalive会自动启动nginx，确保服务的连续性和可用性。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
