Reloading systemd: [ OK ]
Starting keepalived (via systemctl): [ OK ]
访问：
#### docker01和docker02做反向代理：
#### docker01:
[root@nginx01 ~]# vim /usr/local/nginx1.14/conf/nginx.conf
21行添加：
upstream backend {
ip_hash;
server 192.168.1.30:80 weight=1 max_fails=2 fail_timeout=10s;
server 192.168.1.40:80 weight=1 max_fails=2 fail_timeout=10s;
}
49行添加：
proxy_pass http://backend;
重启服务：
[root@nginx01 ~]# nginx -t
nginx: the configuration file /usr/local/nginx1.14/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx1.14/conf/nginx.conf test is successful
[root@nginx01 ~]# nginx -s reload
#### docker02:
33行添加：
upstream backend {
ip_hash;
server 192.168.1.30:80 weight=1 max_fails=2 fail_timeout=10s;
server 192.168.1.40:80 weight=1 max_fails=2 fail_timeout=10s;

#### 做NFS的Rsync+Inotify
#### nfs01:
[root@nfs01 ~]# tar zxf inotify-tools-3.14.tar.gz
[root@nfs01 ~]# cd inotify-tools-3.14/
[root@nfs01 inotify-tools-3.14]# ./configure && make && make install
[root@nfs01 inotify-tools-3.14]# vim /etc/rsyncd.conf
最后一行添加：
gid = nobody
use chroot = yes
address = 192.168.1.50
port 873
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = 192.168.1.0/24
[wwwroot]
path = /datashare
read only = no
dont compress = .gz .tgz .zip .z .Z .rpm .deb .bz2
#### 编写脚本来实现实时同步：
[root@nfs01 ~]# vim /inotify_sync.sh
#!/bin/bash
inotify_cmd="inotifywait -mrq -e modify,create,attrib,move,delete /datashare"
rsync_cmd="rsync -azH /datashare/* 192.168.2.40::wwwroot"
$inotify_cmd | while read DIRECTORY EVENT FILE
do
$rsync_cmd
done
[root@nfs01 ~]# chmod +x /inotify_sync.sh
启动服务：
[root@nfs01 ~]# rsync --daemon
#### nfs02：
[root@nfs02 ~]# yum -y install rsync
[root@nfs02 ~]# vim /etc/rsyncd.conf
uid = nobody
gid = nobody
use chroot = yes
address = 192.168.1.60
port 873
log file = /var/log/rsyncd.log
pid file = /var/run/rsyncd.pid
hosts allow = 192.168.1.0/24
[wwwroot]
path = /datashare
read only = no
dont compress = .gz .tgz .zip .z .Z .rpm .deb .bz2
[root@nfs02 ~]# mkdir /datashare
#### nfs01:
[root@nfs01 ~]# sh /inotify_sync.sh
nfs02：
#### 验证：
[root@nfs02 ~]# cat /datashare/
