Haproxy+keepalived如何實現sphinx高可用負載均衡詳解

下文給大家帶來Haproxy+keepalived如何實現sphinx高可用負載均衡詳解，希望能夠給大家在實際運用中帶來一定的幫助，負載均衡涉及的東西比較多，理論也不多，網上有很多書籍，今天我們就用億速云在行業內累計的經驗來做一個解答。

Haproxy+keepalived實現sphinx高可用負載均衡  

環境如下：
【node3】
haproxy：192.168.1.189
【node4】
haproxy：192.168.1.103
vip：192.168.1.222/192.168.1.223

# apt-get install ipvsadm 
# apt-get install linux-headers-$(uname -r)
# ln -s /usr/src/linux-headers-2.6.32-33 /usr/src/linux
# wget http://www.keepalived.org/software/keepalived-1.2.2.tar.gz
# tar zxvf keepalived-1.2.2.tar.gz -C ../software/
# ./configure --prefix=/usr/local/keepalived-1.2.2
configure: error:!!! OpenSSL is not properly installed on your system. !!!!!! Can not include OpenSSL headers files.解決辦法：
# apt-get install libssl-dev
configure: error: Popt libraries is required
解決辦法：
# apt-get install libpopt-dev
configure: WARNING: keepalived will be built without libnl support.
解決辦法：
# apt-get install libnl-dev
/usr/include/stdint.h:41: error: conflicting types for ‘int64_t’
/usr/src/linux/include/linux/types.h:125: error: previous declaration of ‘int64_t’ was here
/usr/include/stdint.h:56: error: conflicting types for ‘uint64_t’
解決辦法：
# vim ./keepalived/libipvs-2.6/ip_vs.h
將#include <linux/types.h>移動到#include <sys/types.h>后面去。

# ./configure --prefix=/usr/local/keepalived-1.2.2
