#LD_RUN_PATH=$BASE/openssl/lib:/usr/local/mysql5.1/lib:$BASE/zlib/lib:$BASE/gd/lib:$BASE/libxml2/lib:$BASE/curl/lib
export LD_RUN_PATH
1.)ZLIB
ZLIB=$BASE/zlib
tar xzf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure --prefix=$ZLIB
make && make install
2.)LIBICONV

安装软件时的/usr/local/lib/libz.a(compress.o)错误

/usr/bin/ld: /usr/local/lib/libz.a(compress.o): relocation R_X86_64_32 against `a local symbol' can not be used when

making a shared object; recompile with -fPIC
/usr/local/lib/libz.a: could not read symbols: Bad value

解决办法 : 重新安装 zlib-1.2.3.tar.gz

tar -zxvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure

vi Makefile
找到 CFLAGS=-O3 -DUSE_MMAP
在后面加入-fPIC，即变成CFLAGS=-O3 -DUSE_MMAP -fPIC
接下面步骤

make
make install

6.)LIBXML
LIBXML=$BASE/libxml2
tar xzf libxml2-sources-2.6.32.tar.gz
cd libxml2-2.6.32
./configure --prefix=$LIBXML --with-iconv=$BASE/gd --with-zlib=$BASE/zlib
make & make install
7.)GD

tar xzf gd-2.0.35RC4.tar.gz
cd gd-2.0.35RC4
./configure --prefix=$GD --with-png=$BASE/gd/ --with-freetype=$BASE/gd/ --with-jpeg=$BASE/gd/

make & make install

8.)OPENSSL
OPENSSL=$BASE/openssl
./config --prefix=$OPENSSL no-threads shared -fPIC
make && make test && make install
9.)MYSQL
tar xzf mysql-5.1.25-rc.tar.gz
cd mysql-5.1.25-rc
CFLAGS="-O3 -mpentiumpro"
CXX="gcc"
CXXFLAGS="-O3 -mpentiumpro -felide-constructors"
export CFLAGS CXX CXXFLAGS

MYSQL_BASE=$BASE/mysql

Mysql 编译参数汇总：
http://blog.chinaunix.net/uid-21505614-id-289451.html

./configure --prefix=$BASE/mysql --enable-assembler \
--with-charset=gbk --with-extra-charsets=gb2312,latin1,utf8 \
--enable-largefile --with-big-tables --without-debug --with-max-indexes=64 \
 --with-zlib-dir=$ZLIB_BASE \
 --with-mysqld-ldflags=-all-static --without-ndbcluster
make & make install

【安装后建立服务】
mkdir $MYSQL_BASE/var
 cp mysql-version/share/mysql/my-large.cnf $MYSQL_BASE/var/my.cnf

 cp mysql-version/mysql-5.1.34/support-files/mysql.server  /etc/init.d/mysql

 

 $MYSQL_BASE/bin/mysql_install_db

 chown -Rcf mysql:mysql $MYSQL_BASE

 

 redhat\centos : chkconfig --add mysql ; service mysql start

 Ubuntu 9.04 : update-rc.d mysql defaults ; service mysql start

 

【注意】

如果提示”/usr/local/php-5.2.5/sapi/cli/php:error while loading shared libraries: /usr/local/mysql/lib/libmysqlclient.so.16:cannot restore segment prot after reloc: Permission denied”

原因：SELinux

解决方法：chcon –t texrel_shlib_t /usr/local/mysql/lib/libmysqlclient.so.16

 

编译mysql源码时碰到如下问题

checking for tgetent in -ltermcap... no
checking for termcap functions library... configure: error: No curses/termcap library found

 

需要安装ncurses-5.2.tar.gz，安装好之后把安装路径设置到PATH中.或者加参数

 

Redhat/Centos : --with-named-curses-libs=/usr/lib/libncursesw.so.5

 

Ubuntu 9.04 : --with-named-curses-libs=/lib/libncursesw.so.5

 

【增加innodb支持】

--with-plugins=innobase

my.cnf Example :

[mysqld]

innodb_data_home_dir  =  /mysql/var
innodb_data_file_path  =  ibdata1:2000M;ibdata2:200M:autoextend
innodb_log_group_home_dir  =  /mysql/var
set-variable  =  innodb_mirrored_log_groups=1
set-variable  =  innodb_log_files_in_group=3
set-variable  =  innodb_log_file_size=30M
set-variable  =  innodb_log_buffer_size=8M
innodb_flush_log_at_trx_commit=1
#innodb_log_arch_dir  =  /mysql/var
#innodb_log_archive=0
set-variable  =  innodb_buffer_pool_size=80M
set-variable  =  innodb_additional_mem_pool_size=10M
set-variable  =  innodb_file_io_threads=4
set-variable  =  innodb_lock_wait_timeout=50

10.)APACHE

export LDFLAGS="-L$BASE/openssl/lib -Wl,-R$BASE/openssl/lib"
       export CPPFLAGS="-I$BASE/openssl/include"
 ./configure --prefix=$BASE/apache --enable-ssl --with-ssl=$BASE/openssl \
   --enable-so --enable-mods-shared=most \
  --enable-dav --enable-maintainer-mode
make &&make install

 

服务器在装好CentOS5.2后，开始安装MySql+httpd+php+other，和以往一样进行安装，除了Apache2安装出现了“/usr/lib/libexpat.so: could not read symbols: File in wrong format ”问题以外，其它软件一切正常，以下是我对apache编译configure后进行make遇到的问题：

/usr/lib/libexpat.so: could not read symbols: File in wrong format

这个问题出现在configure后的make，也就是说configure都能顺利通过，但是在make这一步时确有问题了。/usr/lib/libexpat.so: could not read symbols: File in wrong format

1、删除安装目录下的configure文件，在我的环境中是httpd-2.2.6/configure

2、删除“httpd-2.26/srclib/apr-util/configure”

3、通过以下命令重建编译文件（以下命令在http-2.26/目录下运行）。

#./buildconf

4. 、通过以上重建编译文件，现在可以拥有64位的apr-util了，最后在编辑时加上以上参数：

 ./configure --enable-lib64=/usr/lib64

11.)NET-SNMP
NETSNMP=$BASE/net-snmp
cd net-snmp-$SNMP_VERSION/
./configure --prefix=$NETSNMP --with-openssl=$OPENSSL \
 --with-default-snmp-version=3 \
  --with-sys-location=Unknown \
 --with-logfile=/var/log/snmpd.log --with-persistent-directory=/var/net-snmp
make
make install
cd ..

$BASE/net-snmp/sbin/snmpd -c /etc/snmp/snmpd.conf -Lsd -Lf /dev/null -p /var/run/snmpd.pid -a
12.)PHP

./configure --prefix=$BASE/php --with-apxs2=$BASE/apache/bin/apxs \
 --with-openssl=$BASE/openssl --with-mysql=$BASE/mysql \
 --with-zlib-dir=$BASE/zlib --with-jpeg-dir=$BASE/gd \
 --with-png-dir=$BASE/gd --with-freetype-dir=$BASE/gd \
 --with-ttf --enable-gd-native-ttf --enable-mbstring=cn \
 --with-gd --enable-sockets --enable-bcmath --with-iconv-dir=$BASE/gd \

 --with-snmp=$BASE/net-snmp \
 --with-libxml-dir=$BASE/libxml2

# --without-sqlite --disable-json 有待验证

make
make install

cp php.ini-dist $PHP_BASE/lib/php.ini

如果操作系统已经使用yum安装依赖工具包，那么在编译php5.4.16，用来支持zabbix 2.0.6可以使用如下php编译配置参数：

./configure --prefix=/opt/php  --enable-fpm --with-mcrypt --with-zlib\
--disable-pdo --with-curl --disable-debug  --disable-rpath\
--enable-inline-optimization --with-bz2  --with-zlib=/usr --enable-sockets \
--enable-sysvsem --enable-sysvshm --enable-pcntl --enable-mbregex\
--with-mhash --enable-zip --with-pcre-regex --with-mysql\
--with-jpeg --with-curl=/usr --enable-gd-native-ttf \
--with-iconv-dir=/usr --enable-mbstring=all --with-gd \
--with-png-dir=/usr --with-jpeg-dir=/usr --with-freetype-dir=/usr \
--enable-bcmath --with-gettext=/usr

#修改 $APACHE_BASE/conf/httpd.conf
AddType application/x-httpd-php .php .phtml .php4 .inc
DirectoryIndex index.php

13.)CURL

监控页面图形展，中文乱码 

 zabbix监控服务器，但是配置过程中发现当有中文时，图中的中文会变成方块
这个问题是由于zabbix的web端没有中文字库，我们最需要把中文字库加上即可
解决办法如下
1.从Windows 7下控制面板->字体->选择一种中文字库例如“宋体 常规”
2.把它拷贝到zabbix的web端的fonts目录下例如：/var/www/html/zabbix/fonts，并且把TTF后缀改为ttf
3.修改zabbix的web端/include/defines.inc.php

//define('ZBX_FONT_NAME', 'DejaVuSans');
define('ZBX_FONT_NAME', 'simsun');

//define('ZBX_GRAPH_FONT_NAME', 'DejaVuSans'); // font file name
define('ZBX_GRAPH_FONT_NAME', 'simsun');
// font file name

其中SIMSUN为字库名字,不包含ttf后缀，Web界面刷新即可。

用zabbix监控磁盘性能

Add the following code to your zabbix_agentd.conf file (/etc/zabbix/zabbix_agentd.conf by default), and restart the zabbix agent:

UserParameter=custom.vfs.dev.read.ops[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$4}’
UserParameter=custom.vfs.dev.read.ms[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$7}’
UserParameter=custom.vfs.dev.write.ops[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$8}’
UserParameter=custom.vfs.dev.write.ms[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$11}’
UserParameter=custom.vfs.dev.io.active[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$12}’
UserParameter=custom.vfs.dev.io.ms[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$13}’
UserParameter=custom.vfs.dev.read.sectors[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$6}’
UserParameter=custom.vfs.dev.write.sectors[*],cat /proc/diskstats | grep $1 | head -1 | awk ‘{print $$10}’

Zabbix monitor Oracle

1. 安装oracle开发库

2. 安装zabbix --with-oracle 支持

完善中...

Zabbix monitor Mysql

 

 Mysql同步（复制）启动后，要满足以下两个条件才算是成功，即：
Slave_IO_Running: Yes Slave_SQL_Running: Yes
一个脚本文件，mysqlms.sh

#!/bin/bash
/usr/local/mysql/bin/mysql -uzabbix -e 'show slave status\G' |grep -E "Slave_IO_Running|Slave_SQL_Running"|awk '{print $2}'|grep -c Yes

zabbix告警配置

参考: 

http://waringid.blog.51cto.com/65148/1142579
因为zabbix发送告警邮件提醒，默认不支持邮件认证方式发送。需要改为使用脚本发邮件的方式来报警的，脚本名字定义为 warn，放在/usr/local/bin/目录下。
warn脚本内容如下：

#!/bin/bash
echo "$3" | sudo /usr/local/bin/mutt -F /usr/local/etc/.muttrc -s "$2" $1 >> /var/log/mutt.log 2>&1

在告警配置页里的脚本名称不写目录的绝对路径，直接写脚本名字，脚本的路径设置是在zabbix服务器端的配置文件中，在zabbix_server.conf配置
使用参数设置：
AlertScriptsPath=/usr/local/bin/
脚本调用mutt + msmtp的方式发送邮件，相关安装配置可以参考 ： http://blog.chinaunix.net/uid-16974460-id-295828.html
其中我在测试过程中发现mutt在非root用户下工作不正常，因为zabbix_server在调用脚本时使用的是zabbix用户，需要通过sudo授权。
/etc/sudoers中添加配置：  
zabbix ALL=(root) /usr/local/bin/mutt
# Defaults    requiretty #同时注释此行内容，否则脚本在执行时会出现错误“sudo: sorry, you must have a tty to run sudo”。
