varnish安裝使用（初學）
本人對varnish也是新手，這裡記錄一下安裝步驟！
環境：centos6.6
先上我的拓撲圖 （基礎拓撲為lvsdr環境） lvs不在這裡講解
安裝yum -y install gcc gcc-c++ make autoconf automake
yum -y install automake autoconf libtool ncurses-devel libxslt groff pcre-devel pkgconfig readline-devel
tar -zxf varnish-3.0.7.tar.gz
cd varnish-3.0.7
./configure --prefix=/usr/local/varnish
make;make install
拷貝檔案到系統
cp redhat/varnish.initrc /etc/init.d/varnish
cp redhat/varnish.sysconfig /etc/sysconfig/varnish
cp redhat/varnish_reload_vcl /usr/local/varnish/bin
修改varnish配置檔案
vim /etc/sysconfig/varnish
修改為如下內容 （裡面有許多varnish的效能配置）
varnish_vcl_conf=/usr/local/varnish/etc/varnish/default.vcl
varnish_listen_port=80
varnish_secret_file=/usr/local/varnish/etc/varnish/secret
vim /etc/init.d/varnish
pidfile=/var/run/varnish.pid
exec="/usr/local/varnish/sbin/varnishd"
reload_exec="/usr/local/varnish/bin/varnish_reload_vcl"
# done parsing, set up command
varnishadm="/usr/local/varnish/bin/varnishadm $secret -t $varnish_admin_listen_address:$varnish_admin_listen_port"
注:也可以將/usr/local/varnish/bin新增到系統的path中,這樣就不需要編輯varnish_reload_vcl
生成varnish管理秘鑰:
/usr/bin/uuidgen > /usr/local/varnish/etc/varnish/secret
chmod 644 /usr/local/varnish/etc/varnish/secret
vcl配置（對應拓撲圖）
#獲取客戶端ip
# if (req.restarts == 0) else
# }
}檢查vcl配置是否正確:
/etc/init.d/varnish configtest
或/usr/local/varnish/sbin/varnishd -c -f /usr/local/varnish/etc/varnish/fdfs.vcl #啟動varnish:
service varnish start #檢視varnish狀態:
/etc/init.d/varnish status # 動態載入vcl配置:
/etc/init.d/varnish reload # 停止varnish:
/etc/init.d/varnish stop
先就說這麼多吧
