背景：所有主机要求纳入it监控中，监控软件sysstat能实现主机基础性能的采集。sar -V检查原版本为9.0.4，不能满足要求升级为11.5.5
sysstat安装
安装前需确认系统是否已安装gcc，运行如下命令，redhat5以上版本使用自带的gcc即可：
1.删除原有老版本sysstat
[root@node-x]# rpm -e --nodeps sysstat
2.解压sysstat源码
[root@node-x]# xz -d sysstat-11.5.5.tar.xz
[root@node-x]# tar xf sysstat-11.5.5.tar
3.安装前环境监测
[root@node-x]# cd sysstat-11.5.5
[root@node-x sysstat-11.5.5]# ./configure
.
Check programs:

……
环境未具备，程序返回结果会报错,这里正常
4.编译安装sysstat源码
[root@node-x sysstat-11.5.5]# sa_lib_dir=/usr/lib/sa \
sa_dir=/var/log/sa \
conf_dir=/etc/sysconfig \
./configure --prefix=/usr \
--disable-file-attr && make && make install
5.设置sysstat全局变量及开机启动
ln -s /安装路径/sysstat-11.5.5/sysstat /usr/local/bin/
ln -s /安装路径/sysstat-11.5.5/sysstat /etc/init.d/sysstat
chkconfig --add sysstat
chkconfig --list | grep sysstat
6.手动启动sysstat
[root@node-x sysstat-11.5.5]# /etc/rc.d/init.d/sysstat start
Calling the system activity data collector (sadc)...
