115机器上的角本对上面的角本稍做变动即可
改变 state MASTER -> state BACKUP，priority 100 -> priority 90，mcast_src_ip 192.168.0.118 -> mcast_src_ip 192.168.0.105。其他的地方保持不变，是不是很简单。
! Configuration File for keepalived
vrrp_script chk_nginx {
script "/etc/keepalived/check_nginx.sh"
interval 2
weight -5
}
vrrp_instance VI_1 {
state BACKUP # 修改
interface eth0
mcast_src_ip 192.168.0.105 # 修改 为本机IP
virtual_router_id 51
priority 90 #数字变小
advert_int 2
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
192.168.0.119
}
track_script {
chk_nginx
}
}
到这里keepalived的简单配置就完成了下面就启动keepalived
service keepalived start
安装Nginx
查看nginx的依赖库是否完整
rpm -qa zlib rpm -qa zlib-devel rpm -qa openssl rpm -qa openssl-devel rpm -qa pcre rpm -qa pcre-devel rpm -qa gcc
如果没有就安装
yum -y install gcc zlib zlib-devel openssl openssl-devel pcre-devel
下载并解压nginx
mkdir nginxsrc cd nginxsrc/
wget http://nginx.org/download/nginx-1.13.9.tar.gz tar zxvf nginx-1.13.9.tar.gz cd nginx-1.13.9/
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module
安装在/usr/local/nginx/sbin/nginx 目录下
make&&make install
执行成功后会显示leaving directory
启动
/usr/local/nginx/sbin/nginx
检查
ps aux|grep nginx
开机启动
vi /etc/rc.local
添加一行
/usr/local/nginx/sbin/nginx
因为我的机器上80端口被别的应用占用了，所以就修改105和118的 nginx.conf 把端口80 修改为81
vi /usr/local/nginx/conf/nginx.conf
