简单的llmp(Litespeed+mysql+php)安装教程

Cat. — Sat, 11 Sep 2010 10:01:29 +0000

(时间比较急,难免有错误)

Litespeed是商业软件的,但也有免费版,而且免费版功能都很强大了,其中的实时查看每个站的链接数,实时查看每个站的in/out的流量大小.这2个功能就已经非常讨我喜欢了...更多功能,自己安装体验吧,下面是安装教程.

我选择的操作系统是CentOS,mysql版本5.1.50,php版本为5.3.3

首先用yum命令安装,升级所需的程序库

yum -y install yum-fastestmirror
yum -y update
yum -y remove httpd
yum -y install patch make gcc gcc-c++ gcc-g77 flex bison tar
yum -y install libtool libtool-libs kernel-devel autoconf213
yum -y install libjpeg libjpeg-devel libpng libpng-devel
yum -y install freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel
yum -y install file glib2 glib2-devel bzip2 diff* openldap-devel
yum -y install bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs
yum -y install e2fsprogs-devel krb5 krb5-devel libidn libidn-devel
yum -y install openssl openssl-devel vim-minimal unzip vixie-cron
yum -y install fonts-chinese scim-chewing scim-pinyin scim-tables-chinese
export PHP_AUTOCONF=/usr/bin/autoconf-2.13
export PHP_AUTOHEADER=/usr/bin/autoheader-2.13

这里是安装PHP 5.2.3所需的支持库：

wget -c http://catlnmp.googlecode.com/files/libiconv-1.13.1.tar.gz
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../

wget -c http://catlnmp.googlecode.com/files/libevent-1.4.14b-stable.tar.gz
tar zxvf libevent-1.4.14b-stable.tar.gz
cd libevent-1.4.14b-stable/
./configure --prefix=/usr
make
make install
cd ../

wget -c http://catlnmp.googlecode.com/files/libmcrypt-2.5.8.tar.gz
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../

wget -c http://catlnmp.googlecode.com/files/mhash-0.9.9.9.tar.gz
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config

wget -c http://catlnmp.googlecode.com/files/mcrypt-2.6.8.tar.gz
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
./configure
make
make install
cd ../

安装Google的开源TCMalloc库,提高MySQL在高并发情况下的性能

wget -c http://catlnmp.googlecode.com/files/google-perftools-1.6.tar.gz
tar zxvf google-perftools-1.6.tar.gz
cd google-perftools-1.6/
./configure
make && make install
echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf
/sbin/ldconfig
cd ../

现在安装mysql

wget -c http://catlnmp.googlecode.com/files/mysql-5.1.50.tar.gz
tar -zxvf mysql-5.1.50.tar.gz
cd mysql-5.1.50
./configure --prefix=/usr/local/mysql --with-extra-charsets=all --enable-thread-safe-client --enable-assembler --with-charset=utf8 --enable-thread-safe-client --with-extra-charsets=all --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --without-debug --with-mysqld-ldflags=-ltcmalloc_minimal
make && make install
cd ../
groupadd mysql
useradd -g mysql mysql
cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf
/usr/local/mysql/bin/mysql_install_db --user=mysql
chown -R mysql /usr/local/mysql/var
chgrp -R mysql /usr/local/mysql/.
cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql
chmod 755 /etc/init.d/mysql
chkconfig --level 345 mysql on
echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
echo "/usr/local/lib" >>/etc/ld.so.conf
ldconfig
ln -s /usr/local/mysql/lib/mysql /usr/lib/mysql
ln -s /usr/local/mysql/include/mysql /usr/include/mysql
service mysql start
/usr/local/mysql/bin/mysqladmin -u root password shinko //你的密码
service mysql restart

接着安装LiteSpeed

wget http://www.litespeedtech.com/packages/4.0/lsws-4.0.16-std-i386-linux.tar.gz
tar zxvf lsws-4.0.16-std-i386-linux.tar.gz
cd lsws-4.0.16
./install.sh

出现--More--（27%）的许可协议,可以直接按空格键或者回车跳到最后.
Do you agree with above license? #这里需要输入Yes （Y要大写）
下面的基本一直回车和选Y就OK了

安装完成就可以访问http://IP:7080来管理LiteSpeed,

最后就是安装php了,在litespeed控制面板选择Compile PHP
然后选择要安装的php版本,我这里选择php5.3.3,然后用以下参数编译

--with-mysql=mysqlnd --with-mysqli=mysqlnd --with-iconv=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --enable-ftp --disable-debug --with-gettext --with-openssl

然后下一步,是程序自动下载安装文件,下载完成后继续下一步,就去到安装画面了.在ssh下运行这句语句,

/usr/local/lsws/phpbuild/buildphp_manual_run.sh

等待几分钟就会安装完成了,如果安装失败,请查看log错误...

暧味日志

删除Mysql的MySql-bin.0000X日志文件

Cat. — Wed, 26 May 2010 13:32:09 +0000

装mysql,运行一段时间后，在mysql目录下出现一堆类似 mysql-bin.000***，从mysql-bin.000001开始一直排列下来，而且占用了大量硬盘空间，高达几十个G. 对于这些超大空间占用量的文件我们应该怎么办呢?

我的数据库加起来大概100M吧..但/usr/local/mysql/var这个目录竟然有548M,MySql-bin.0000文件大概占了400+M,真浪费空间啊

那么mysql数据库文件夹中的mysql-bin.00001是什么文件？

mysql-bin.000001、mysql- bin.000002等文件是数据库的操作日志，例如UPDATE一个表，或者DELETE一些数据，即使该语句没有匹配的数据，这个命令也会存储到日志文件中，还包括每个语句执行的时间，也会记录进去的。

那么这些文件该怎么删除和禁止呢?
禁止方法: vi /etc/my.cnf把里面的
#log-bin=mysql-bin
#binlog_format=mixed
注释掉,重启mysql服务即可.

删除方法:

输入命令:

/usr/local/mysql/bin/mysql -u root -p

输入密码登陆mysql后,运行命令:

reset master;

(包括;号)

清空日志文件.再查看Mysql文件的大小,已经小了很多了.

-bash-3.2# du -h –max-depth=1 /usr/local/mysql/var
du: cannot access `250Cmax-depth=1': No such file or directory
142M /usr/local/mysql/var

mkdir -p /usr/local/zend/
cp ZendOptimizer-3.3.9-linux-glibc23-x86_64/data/5_2_x_comp/ZendOptimizer.so /usr/local/zend/

配置php.ini

cat >>/usr/local/php/etc/php.ini<

7,修改php.ini文件
手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"

再查找 output_buffering = Off
修改为output_buffering = On

自动修改:可执行以下shell命令,自动完成对php.ini文件的修改:

sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"nextension = "memcache.so"nextension = "pdo_mysql.so"n#' /usr/local/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/php/etc/php.ini

8,配置eAccelerator加速PHP:
创建缓存目录

mkdir -p /usr/local/eaccelerator_cache

配置php.ini

cat >>/usr/local/php/etc/php.ini< [eaccelerator]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
EOF

9,创建www用户和组,以及主机需要的目录,日志目录

groupadd www
useradd -g www www
mkdir -p /home/www
chmod +w /home/www
mkdir -p /home/www/logs
chmod 777 /home/www/logs
chown -R www:www /home/www

10,创建php-fpm配置文件

rm -f /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf

输入以下内容,我设置开的进程是5个.需要更改进程数,可以修改5

11,启动php-cgi进程,监听127.0.0.1的9000端口,进程数为5,用户为www

ulimit -SHn 65535
/usr/local/php/sbin/php-fpm start

12,安装Nginx

tar zxvf pcre-8.01.tar.gz
cd pcre-8.01/
./configure
make && make install
cd ../

tar zxvf nginx-0.7.65.tar.gz
cd nginx-0.7.65/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module
make && make install
cd ../

13,创建Nginx配置文件

mkdir -p /usr/local/nginx/conf/servers
rm -f /usr/local/nginx/conf/nginx.conf
vi /usr/local/nginx/conf/nginx.conf

输入以下内容:

user www www;
worker_processes 1;
error_log /home/www/logs/nginx_error.log crit;

#limit_zone crawler $binary_remote_addr 10m;

server
{
listen 80;
server_name vps.imcat.in;
index index.html index.htm index.php;
include location.conf;
root /home/www;
}
include servers/*;
}

14,在/usr/local/nginx/conf/目录中创建location.conf文件：

vi /usr/local/nginx/conf/location.conf

输入内容:

location ~ .*.(php|php5)?$
{
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}

location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}

location ~ .*.(js|css)?$
{
expires 12h;
}

多站点管理,可以在/usr/local/nginx/conf/servers目录添加配置文件,格式为:

vi /usr/local/nginx/conf/servers/imcat.conf

内容:

server

{
listen 80;
server_name imcat.in;
index index.html index.htm index.php;
root /home/www/imcat;
}

请注意,我是没有开启Nginx日志记录功能的.
启动Nginx:

ulimit -SHn 65535
/usr/local/nginx/sbin/nginx

放个探针看看

mv index.php /home/www/

访问你的IP看看吧!

15,安装phpMyAdmin,管理Mysql数据库

tar zxvf phpMyAdmin-3.2.4-all-languages.tar.gz
mv phpMyAdmin-3.2.4-all-languages /home/www/phpmyadmin

16,配置开机自动启动Nginx + PHP

echo "ulimit -SHn 65535" >>/etc/rc.local
echo "/usr/local/php/sbin/php-fpm start" >>/etc/rc.local
echo "/usr/local/nginx/sbin/nginx" >>/etc/rc.local

17,优化Linux内核参数(我只在Xen VPS用过,Openvz VPS失败,慎用)

vi /etc/sysctl.conf

在最后加入

# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog = 32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024 65535

使配置立即生效：

/sbin/sysctl -p

18,需要安装ftp的,可以简单安装vsftpd应用:

yum -y install vsftpd
/etc/init.d/vsftpd start
chkconfig --level 345 vsftpd on

19,请务必更改www用户密码:

passwd www

debian安装nginx+php(spawn-fcgi)+mysql

Cat. — Wed, 02 Dec 2009 12:20:14 +0000

前天购买了linode最低的那款VPS,一直用的都是CentOS系统,所以这次就试了试debian ,毕竟国外debian使用率占了半壁江山

linode的控制面板很好用,很方便,一下就安装debian 5.0 ,下载是昨天安装nginx+php(spawn-fcgi)+mysql 的记录

首先是添加源地址,目的只有一个,我要安装最新版的软件,debian默认的软件版本低啊

vi /etc/apt/sources.list
deb http://packages.dotdeb.org lenny all

接着,当然是更新一下系统啦.
apt-get update

下面是安装mysql5.1,安装过程会需要你输入root密码的

apt-get install mysql-server-5.1
/etc/init.d/mysql restart
/etc/init.d/mysql stop

接着是PHP5,自己选择需要安装的扩展吧

apt-get install php5-common php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl php5-apc

安装nginx,代码如果下

apt-get install libpcre3 libpcre3-dev libpcrecpp0 libssl-dev zlib1g-dev build-essential
wget http://sysoev.ru/nginx/nginx-0.7.64.tar.gz
tar zxvf nginx-0.7.64.tar.gz
cd nginx-0.7.64/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module --with-http_ssl_module
make
make install
cd ../

最后安装spawn-fcgi,用来启动PHP的

wget http://www.lighttpd.net/download/spawn-fcgi-1.6.3.tar.gz
tar -zxf spawn-fcgi-1.6.3.tar.gz
cd spawn-fcgi-1.6.3
./configure --bindir=/usr/bin --libdir=/usr/lib --prefix=/etc
make&&make install

启动方法是

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 8 -u www -g www -f "/usr/bin/php5-cgi -d /var/www"
/usr/local/nginx/sbin/nginx

这只是一篇简单的记录日志,没有给出配置文件,配置文件用一键包的就OK,另外,我还没弄好开机启动 php 和 nginx 的脚本,所以每次都要手动运行.

一定要修改的mysql默认预设值

Cat. — Tue, 17 Nov 2009 03:09:42 +0000

Jeremy Zawodny写了一篇Fixing Poor MySQL Default Configuration Values 关于mysql默认预设值的问题,其中提到了有4点是无论如何都要修改的.

首先是 max_connect_errors , 当某一个网站送了很多错误的请求时,mysql服务器就会当掉这个网站的权限.

第三个是 skip-name-resolve 这个设定很变态的,每一次链接都要做一次反DNS查询,mysql跑反DNS查询有什么用,浪费时间和资源.

最后我在my.cnf配置文件添加了以下语句:

max_connect_errors = 1844674407370954751
connect_timeout = 30
skip-name-resolve
slave_net_timeout = 30

自动备份mysql数据库并发送到Email

Cat. — Tue, 30 Jun 2009 14:39:26 +0000

一个博客,一个网站最重要的就是数据库,所以经常备份数据是必须的.尽管 WordPress 有定时备份数据的插件,但只能备份当前的博客,不够灵活.适合个人小小博客,对于一些网站来说,就不适合了.现在很多人都拥有多个网站,showfom 同学就有几个网站.每个网站都装个插件就比较麻烦了.况且不是每个网站都是 WordPress 的 .

所以写了个自动备份mysql数据库的脚本,再加上gmail这个G级邮箱,备份多少数据都可以了...下面是代码:

mysqldump -uuser -ppassword --databases db1 db2 db3 > /home/website/backups/databackup.sql
tar zcf /home/website/backups/databackup.sql.tar.gz /home/website/backups/
echo "主题:数据库备份" | mutt -a /home/website/backups/databackup.sql.tar.gz -s "内容:数据库备份" www@gmail.com
rm -r /home/website/backups/*

将上面的代码保存为automysqlbackup.sh
然后利用crontab 实现动备份,在ssh下,

crontab -e

输入以下内容:

00 00 * * * /home/website/automysqlbackup.sh

这样就实现了每天00:00自动备份mysql数据库并发送到Email

简单的说明下吧.
第一句是一次性备份多个数据库,这个要你用root权限的用户才可以的..-u后面的是数据库用户名 -p后面的是数据库密码无需空格 db1 db2 db3为你需要备份的数据库名.
如果你的数据库用户名没有root这个权限,可以改为这样

mysqldump -uuser -ppassword db1 > /home/website/backups/db1.sql
mysqldump -uuser -ppassword db2 > /home/website/backups/db1.sql
mysqldump -uuser -ppassword db3 > /home/website/backups/db1.sql

第二句是将 backups 文件夹里面的数据文件压缩为文件名:databackup.sql.tar.gz

第三句是将压缩了的数据库文件发送到指定的邮箱.....

其中的主题:数据库备份 ,就是邮件的主题, 内容:数据库备份,就是邮件的内用,

/home/website/backups/databackup.sql.tar.gz 为附件

www@gmail.com为要发送的Email
