keepalived入门之编译安装(2)

上一节我们讲到了keepalived的基本介绍以及其工作原理及相关组成部分，本小节，我们将会讲到keepalived的相关./configure，编译，安装等介绍一. 编译安装keepalived1.1 keepalived的源码获取 keepalived源码包我们可以到keepalived的官网:http://www.keepalived.org/去下载，相关说明文档亦可在其官网查看，比如keepalived的使用，相关配置说明，这里演示的版本为:1.2.15

# wget http://www.keepalived.org/software/keepalived-1.2.15.tar.gz

1.2 安装keepalived的依赖包下载后keepalived源码包后，我们还需要安装keepalived依赖的依赖包，比如:openssl , popt [b]# yum install openssl openssl-devel popt popt-devel[/b]1.3 编译，安装keepalived
<--编译安装keepalived-->

# tar zxvf keepalived-1.2.15.tar.gz -C /usr/local/src
# cd /usr/local/src/keepalived-1.2.15/
# ./configure \
--prefix=/usr/local/keepalived \
--sbindir=/usr/local/keepalived/sbin
# make
# make install

<--对keepalived进行相关优化-->

<---拷贝keepalived相关启动命令--->
# cp /usr/local/keepalived/sbin/keepalived /usr/sbin/
# cp /usr/local/keepalived/etc/sysconfig/keepalived /etc/sysconfig/
<---将keepalived启动脚本添加到系统服务--->
# cp /usr/local/keepalived/etc/rc.d/init.d/keepalived /etc/init.d/
# chkconfig --add keepalived
# chkconfig --level 2345 keepalived on
<---创建keepalived相关配置文件--->
# mkdir -p /etc/keepalived
# cp /usr/local/keepalived/etc/keepalived/keepalived.conf /etc/keepalived

备注说明：
1.keepalived安装完成后，安装目录为:/usr/lccal/keepalived, 配置文件路径为:/etc/keepalive/
2.安装完成后，需要将启动脚本复制到/etc/ini.d/下
3.注意一定要执行述上的相关操作，不然有可能导致keepalived服务起不来
4.关于keepalived相关./configure等参数我们可以利用:./configure --help来查看，以下为keepalived的./configure相关参数说明如下

Configuration:
-h, --help              display this help and exit
--help=short        display options specific to this package
--help=recursive    display the short help of all the included packages
-V, --version           display version information and exit
-q, --quiet, --silent   do not print `checking ...' messages
--cache-file=FILE   cache test results in FILE [disabled]
-C, --config-cache      alias for `--cache-file=config.cache'
-n, --no-create         do not create output files
--srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
--prefix=PREFIX         install architecture-independent files in PREFIX
[/usr/local]
--exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
[PREFIX]

By default, `make install' will install all the files in
`/usr/local/bin', `/usr/local/lib' etc.  You can specify
an installation prefix other than `/usr/local' using `--prefix',
for instance `--prefix=$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
--bindir=DIR            user executables [EPREFIX/bin]
--sbindir=DIR           system admin executables [EPREFIX/sbin]
--libexecdir=DIR        program executables [EPREFIX/libexec]
--sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR     modifiable single-machine data [PREFIX/var]
--libdir=DIR            object code libraries [EPREFIX/lib]
--includedir=DIR        C header files [PREFIX/include]
--oldincludedir=DIR     C header files for non-gcc [/usr/include]
--datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
--datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR           info documentation [DATAROOTDIR/info]
--localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
--mandir=DIR            man documentation [DATAROOTDIR/man]
--docdir=DIR            documentation root [DATAROOTDIR/doc/PACKAGE]
--htmldir=DIR           html documentation [DOCDIR]
--dvidir=DIR            dvi documentation [DOCDIR]
--pdfdir=DIR            pdf documentation [DOCDIR]
--psdir=DIR        ps documentation [DOCDIR]

Optional Features:
--disable-option-checking  ignore unrecognized --enable/--with options
--disable-FEATURE       do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG]  include FEATURE [ARG=yes]
--disable-lvs-syncd     do not use LVS synchronization daemon
--disable-lvs           do not use the LVS framework
--disable-vrrp          do not use the VRRP framework
--disable-fwmark        compile without SO_MARK support
--enable-snmp           compile with SNMP support
--enable-sha1           compile with SHA1 support
--enable-debug          compile with debugging flags
--enable-profile        compile with profiling flags

Optional Packages:
--with-PACKAGE[=ARG]    use PACKAGE [ARG=yes]
--without-PACKAGE       do not use PACKAGE (same as --with-PACKAGE=no)
--with-kernel-dir=DIR   path to linux kernel source directory
--with-kernel-version=VER forced value for linux kernel version (VER=2.4|2.6)

Some influential environment variables:
CC          C compiler command
CFLAGS      C compiler flags
LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
LIBS        libraries to pass to the linker, e.g. -l<library>
CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
you have headers in a nonstandard directory <include dir>
CPP         C preprocessor

二:启动keepalived服务

# service keepalived start
如果keepalived已经启动，这时我们就可以查看以下命令查看启动情况：
# service keepalived status
或
# ps aux | grep keepalived

到这里，keepalived部署基本OK，下一章，我们将会讲到keepalived相关配置
