線上環境安裝測試說明
兩臺測試機
nginx+keepalived做后端LNMP及tomcat+jdk+mysql的負載高可用

測試環境
centos 6.2 x86_64
IP:192.168.101.77
vip：10.10.10.8

centos 6.2 x86_64
IP:192.168.101.88
vip：10.10.10.8

由于測試環境，兩臺都安裝同樣的服務

安裝過程

192.168.101.77和192.168.101.88 安裝nginx+keepalived
安裝依賴包
yum -y install cmake gcc gcc-c++ make zlib zlib-devel openssl* popt popt-devel pcre pcre-devel

安裝pcre
[root@open2 src]# tar jxvf pcre-8.20.tar.bz2 ? ? ? ?
[root@open2 src]# cd pcre-8.20 ? ? ? ? ? ? ? ? ? ? ? ? ? ?
[root@open2 pcre-8.20]# ./configure --prefix=/usr/local/app/pcre
[root@open2 pcre-8.20]# make && make install
[root@open2 pcre-8.20]# cd ..

安裝nginx
[root@open2 src]# tar zxvf nginx-1.5.6.tar.gz
[root@open2 src]# cd nginx-1.5.6
[root@open2 nginx-1.5.6]# ./configure --prefix=/usr/local/app/lbnginx --with-pcre=/usr/src/pcre-8.20
[root@open2 nginx-1.5.6]# make
[root@open2 nginx-1.5.6]# make install
[root@open2 nginx-1.5.6]# cd ..

安裝keepalived
[root@open2 src]# tar zxvf keepalived-1.2.8.tar.gz ? ? ? ? ?
[root@open2 src]# cd keepalived-1.2.8 ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
[root@open2 keepalived-1.2.8]# ./configure --prefix=/usr/local/app/keepalived
[root@open2 keepalived-1.2.8]# make
[root@open2 keepalived-1.2.8]# make install

配置文件，啟動腳本
[root@open2 keepalived-1.2.8]# cp /usr/local/app/keepalived/etc/rc.d/init.d/keepalived /etc/rc.d/init.d/
[root@open2 keepalived-1.2.8]# cp /usr/local/app/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
[root@open2 keepalived-1.2.8]# mkdir /etc/keepalived
[root@open2 keepalived-1.2.8]# cp /usr/local/app/keepalived/etc/keepalived/keepalived.conf /etc/keepalived/
[root@open2 keepalived-1.2.8]# cp /usr/local/app/keepalived/sbin/keepalived /usr/sbin/
[root@open2 keepalived-1.2.8]# chkconfig --level 2345 keepalived on
[root@open2 keepalived-1.2.8]# service keepalived start

192.168.101.77 keepalived配置，192.168.101.88配置一樣只是換一下IP
[root@open2 ~]# cat /etc/keepalived/keepalived.conf

}

測試
本機添加一個10.10.10.9的地址


安裝過程中報錯及解決辦法
1. # ./configure --prefix=/usr/local/app/lbnginx
錯誤提示PCRE庫
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

安裝pcre
[root@open-source src]# tar jxvf pcre-8.20.tar.bz2 ^C ? ? ?
[root@open-source src]# cd pcre-8.20^C ? ? ? ? ? ? ? ? ? ? ?
[root@open-source src]# cd pcre-8.20 ? ? ? ? ? ? ? ? ? ? ? ?
[root@open-source pcre-8.20]# ./configure --prefix=/usr/local/pcre

# ./configure --prefix=/usr/local/app/lbnginx --with-pcre=/usr/local/pcre/

還是PCRE報錯
[root@open-source nginx-1.5.6]# make
make -f objs/Makefile
make[1]: Entering directory `/usr/src/nginx-1.5.6'
cd /usr/local/pcre/lib/ \
? ? ? ?&& if [ -f Makefile ]; then make distclean; fi \
? ? ? ?&& CC="cc" CFLAGS="-O2 -fomit-frame-pointer -pipe " \
? ? ? ?./configure --disable-shared
/bin/sh: line 2: ./configure: No such file or directory
make[1]: *** [/usr/local/pcre/lib//Makefile] Error 127
make[1]: Leaving directory `/usr/src/nginx-1.5.6'
make: *** [build] Error 2

google了一下應該制定pcre源碼目錄
[root@open-source nginx-1.5.6]# ./configure --prefix=/usr/local/app/lbnginx --with-pcre=/usr/src/pcre-8.20
[root@open-source nginx-1.5.6]#make && make install
安裝keepalived
[root@open2 src]# tar zxvf keepalived-1.2.8.tar.gz ? ? ? ? ?
[root@open2 src]# cd keepalived-1.2.8 ?
[root@open-source keepalived-1.2.8]# ./configure --prefix=/usr/local/app/keepalived

2. ? ?# ./configure --prefix=/usr/local/app/keepalived
報錯
configure: error: Popt libraries is required
[root@open-source keepalived-1.2.8]# yum -y install popt popt-devel ? ?
[root@open-source keepalived-1.2.8]# ./configure --prefix=/usr/local/app/keepalived
[root@open-source keepalived-1.2.8]# make && make install
