1、nginx 下载：wget http://nginx.org/download/nginx-1.9.9.tar.gz
2、keepalived 下载：wget http://www.keepalived.org/software/keepalived-1.3.0.tar.gz
3、安装依赖库文件： yum install pcre pcre-devel zlib zlib-devel
4、解压 nginx文件： tar -zxvf nginx-1.9.9.tar.gz -C /usr/local
5、进行configure配置： cd nginx-1.9.9 && ./configure --prefix=/usr/local/nginx
检查通过,表示正常。
出现以上错误，执行命令 yum -y install gcc gcc-c++ autoconf automake make
6、在 nginx-1.9.9 目录里编译安装： make && make install
7、启动nginx： /usr/local/nginx/sbin/nginx
关闭nginx： /usr/local/nginx/sbin/nginx -s stop
重启nginx： /usr/local/nginx/sbin/nginx -s reload
8、查看是否启动：
ps -ef|grep nginx
netstat -anp|grep 80http://192.168.74.155:80 看是否能打开欢迎页面
9、解压keepalived包：tar -zxvf /usr/local/software/keepalived-1.3.0.tar.gz -C /usr/local
155 166 机器都需要装
10、编译keepalived 需要依赖库 yum -install -y openssl openssl-devel
11、进行configure配置：cd keepalived-1.3.0/ && ./configure --prefix=/usr/local/keepalived
12、在 keepalived-1.3.0 目录中执行编译安装的命令： make && make install
出现以上错误： 执行 autoreconf -ivf 然后重新执行 make && make install
出现以上错误： 升级下glib解决 执行 yum update glib* 然后重新执行 make && make install 还是不行，就降低 keepalived版本
13、将keepalived安装成系统服务：
a、创建文件夹，将keepalived配置文件进行复制：
mkdir /etc/keepalived
cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
b、复制keepalived脚本文件 建立两个软链接:
cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
cp /usr/local/keepalived-1.3.0/keepalived/etc/init.d/keepalived /etc/init.d/
ln -s /usr/local/sbin/keepalived /usr/sbin/
ln -s /usr/local/keepalived/sbin/keepalived /sbin/
可以设置开机启动 执行命令：chkconfig keepalived on ，安装完毕
执行命令 service keepalived start
