centos源码LNMP及简单优化

环境介绍：centos6.4_64

首先安装所需要的库

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers cmake

第一部分：安装Mysql5.5.28

1：检查删除自带mysql

rpm -qa|grep mysql

rpm -e --allmatches --nodeps mysql

rm -rf /var/lib/mysql

2：创建MySQL数据库存放目录、配置用户和用户组

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

mkdir -p /yunwei8/mysql/data/

chown -R mysql:mysql /yunwei8/mysql/

3：安装MySQL 5.5.28

mkdir /soft

cd /soft

wget http://down.yunwei8.com/soft/linux/mysql-5.5.28.tar.gz

tar zxvf mysql-5.5.28.tar.gz

cd mysql-5.5.28

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/yunwei8/mysql/data -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -

DWITH_MYISAM_STORAGE_ENGINE=1 -DSYSCONFDIR=/etc/ -DWITH_SSL=yes -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_READLINE=on

make

make install

chmod +w /usr/local/mysql

chown -R mysql:mysql /usr/local/mysql/

4：创建软连接

ln -s /usr/local/mysql/lib/lib* /usr/lib/

5：创建my.cnf配置文件：

#设置Mysql

#在support-files目录中有五个配置信息文件：

#my-small.cnf (内存<=64M)

#my-medium.cnf (内存 128M)

#my-large.cnf (内存 512M)

#my-huge.cnf (内存 1G-2G)

#my-innodb-heavy-4G.cnf (内存 4GB)

cp /usr/local/mysql/support-files/my-large.cnf /etc/my.cnf

vi /etc/my.cnf

在[client]下添加一行

default-character-set = utf8

在[mysqld]下添如下行

character-set-server = utf8 

default-storage-engine = MyISAM

basedir = /usr/local/mysql

datadir = /yunwei8/mysql/data

log-error = /yunwei8/mysql/mysql_error.log

pid-file = /yunwei8/mysql/mysql.pid

在[mysqld]下添加修改

max_allowed_packet = 32M

在[mysqldump]下添加修改

max_allowed_packet = 32M

6：以mysql用户帐号的身份建立数据表：

/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/yunwei8/mysql/data --user=mysql

7：设置mysql开机自动启动服务

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

chkconfig --add mysqld

chkconfig --level 345 mysqld on

8：修改服务配置文件

vi /etc/init.d/mysqld

根据设定需要，修改mysqld文件中的下面两项

basedir=/usr/local/mysql

datadir=/yunwi8/mysql/data

9：启动mysqld服务

service mysqld start

10：通过命令行登录管理MySQL服务器并设置root密码（提示输入密码时直接回车）：

/usr/local/mysql/bin/mysql -u root -p -S /tmp/mysql.sock

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456789');

退出mysql

exit

11：软连接mysql

ln -s /usr/local/mysql/bin/mysql /usr/bin

12：尝试用root连接mysql

mysql -u root -p

成功登录后查看状态

status;

第二部分：mysql优化

为MySQL添加TCMalloc库的安装步骤（Linux环境）：

1、64位操作系统请先安装libunwind库，32位操作系统不要安装。libunwind库为基于64位CPU和操作系统的程序提供了基本的堆栈辗转开解功能，其中包括用于输出堆栈

跟踪的API、用于以编程方式辗转开解堆栈的API以及支持C++异常处理机制的API。

首先下载libunwind-1.1

cd /soft

wget http://down.yunwei8.com/soft/linux/libunwind-1.1.tar.gz

然后安装

tar zxvf libunwind-1.1.tar.gz

cd libunwind-1.1

CFLAGS=-fPIC ./configure

make CFLAGS=-fPIC

make CFLAGS=-fPIC install

2、安装google-perftools：

首先下载gperftools-2.0

cd /soft

wget http://down.yunwei8.com/soft/linux/gperftools-2.0.tar.gz

然后安装

tar zxvf gperftools-2.0.tar.gz

cd gperftools-2.0/

./configure

make && make install

echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf

/sbin/ldconfig

3、修改MySQL启动脚本（根据你的MySQL安装位置而定）：

vi /usr/local/mysql/bin/mysqld_safe

在# executing mysqld_safe的下一行，加上：

export LD_PRELOAD=/usr/local/lib/libtcmalloc.so

保存后退出，然后重启MySQL服务器。

service mysqld restart

4、使用lsof命令查看tcmalloc是否起效：

/usr/sbin/lsof -n | grep tcmalloc

如果发现以下信息，说明tcmalloc已经起效：

mysqld 7395 mysql mem REG 8,2 1943638 194448 /usr/local/lib/libtcmalloc.so.4.1.0

--------------------------------------------------------------华丽分割线--------------------------------------------------------------

nginx优化 使用Google的开源TCMalloc库，提高nginx在高并发情况下的性能 TCMalloc 优化nginx google-perftools优化nginx

第三部分：nginx安装

安装Nginx所需的pcre库

1：下载pcre-8.3.2

cd /soft

wget http://down.yunwei8.com/soft/linux/pcre-8.32.tar.gz

解压并安装

tar zxvf pcre-8.32.tar.gz

cd pcre-8.32/

./configure

make && make install

cd ../

2：创建www用户和组，创建www虚拟主机使用的目录，以及Nginx使用的日志目录，并且赋予他们适当的权限

groupadd www

useradd -g www www

mkdir -p /web/www

chmod +w /web/www

chown -R www:www /web/www

mkdir -p /web/logs

chmod +w /web/logs

chown -R www:www /web/logs

3：为tcmalloc添加目录，并且赋予适当权限

mkdir -p /tmp/tcmalloc/

chown -R www:www /tmp/tcmalloc/

4：安装niginx

下载nginx-1.2.4

wget http://down.yunwei8.com/soft/linux/nginx-1.2.4.tar.gz

解压并安装

tar zxvf nginx-1.2.4.tar.gz

cd nginx-1.2.4/

伪装服务器信息（可以不修改）

vi /soft/nginx-1.2.4/src/core/nginx.h

修改NGINX_VERSION为你希望显示的版号

修改NGINX_VER为你希望显示的名称

修改NGINX_VAR 为你希望显示的名称

引用

./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-

google_perftools_module --with-pcre=../pcre-8.32 --with-pcre-jit

make && make install

安装参数说明看这里：http://www.yunwei8.com/nginxcs

5：修改 nginx.conf ，令nginx可以 google-perftools实现加速

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

修改前面几行为：

user www www;

worker_processes 8;

error_log /web/logs/nginx_error.log crit;

pid logs/nginx.pid;

google_perftools_profiles /tmp/tcmalloc/;

events{

use epoll;

worker_connections 65535;

}

6：测试和运行

增加软连接否则会报错

ln -s /usr/local/lib/libpcre.so.1 /lib64

测试

/usr/local/nginx/sbin/nginx -t

如果显示下面信息，即表示配置没问题

nginx: the configuration file /opt/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /opt/nginx/conf/nginx.conf test is successful

输入代码运行nginx服务

/usr/local/nginx/sbin/nginx

ps aux|grep [n]ginx

如果显以类似下面的信息，即表示nginx已经启动

root 22900 0.0 0.1 43216 1576 ? Ss 08:23 0:00 nginx: master process /usr/local/nginx/sbin/nginx

www 23019 0.0 2.6 68816 27160 ? S 08:48 0:00 nginx: worker process 

www 23020 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process 

www 23021 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process 

www 23022 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process 

www 23023 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process 

www 23024 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process 

www 23025 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process 

www 23026 0.0 2.6 68816 26828 ? S 08:48 0:00 nginx: worker process

输入代码检测是否支持加速

lsof -n | grep tcmalloc

如果显示类似下面的信息，即表示支持tcmalloc加速 (mysqld和nginx八个线程都支持)

mysqld 20818 mysql mem REG 253,0 2177570 281050 /usr/local/lib/libtcmalloc.so.0.2.2

nginx 31655 www 9w REG 8,1 0 479533 /tmp/tcmalloc/.31655

nginx 31656 www 11w REG 8,1 0 479534 /tmp/tcmalloc/.31656

nginx 31657 www 13w REG 8,1 0 479535 /tmp/tcmalloc/.31657

nginx 31658 www 15w REG 8,1 0 479536 /tmp/tcmalloc/.31658

nginx 31659 www 17w REG 8,1 0 479537 /tmp/tcmalloc/.31659

nginx 31660 www 19w REG 8,1 0 479540 /tmp/tcmalloc/.31660

nginx 31661 www 21w REG 8,1 0 479538 /tmp/tcmalloc/.31661

nginx 31662 www 23w REG 8,1 0 479539 /tmp/tcmalloc/.31662

7：编写nginx 启动服务

vi /etc/init.d/nginx

输入以下代码并保存

#!/bin/sh

# chkconfig: - 60 50

# description: nginx web server

# processname: nginx

PATH=/sbin:/usr/sbin:/bin:/usr/bin:/opt/csw/bin:/var/nginx/sbin

NAME=nginx

DAEMON=/usr/local/server/nginx/sbin/nginx

PIDFILE=/usr/local/server/nginx/logs/$NAME.pid

SCRIPTNAME=/etc/init.d/$NAME

[ -x "$DAEMON" ] || exit 0

do_start()

{

if [ -f $PIDFILE ]; then

echo "Nginx program is runing!!!"

exit 1

else 

$DAEMON

echo "Nginx program is the successful start!!! "

fi

}

do_stop()

{

if [ -f $PIDFILE ]; then

kill `cat $PIDFILE`

rm -f $PIDFILE

echo "Nginx program is stoping"

else 

echo "Nginx program is not runing!!!"

fi

}

do_reload ()

{

if [ -f $PIDFILE ]; then

kill -HUP `cat $PIDFILE`

echo "Nginx program is reload"

else

echo "Nginx program is not runing!!!"

fi

}

case "$1" in

start)

do_start

;;

stop)

do_stop

;;

restart)

do_stop

do_start

;;

reload)

do_reload

;;

*)

echo “Usage: $SCRIPTNAME {start|stop|restart|reload}” >&2

;;

esac

保存后，设置权限并添加到启动服务列表中

chmod 755 /etc/init.d/nginx

chkconfig --add nginx

chkconfig --level 345 nginx on

service nginx start

8：防火墙设置

端口开放

/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT

然后保存：

/etc/rc.d/init.d/iptables save

重启防火墙

/etc/init.d/iptables restart

--------------------------------------------------------------华丽分割线--------------------------------------------------------------

第五部分：编译安装PHP5扩展模块

1：安装memcache-2.2.7

wget http://down.yunwei8.com/soft/linux/memcache-2.2.7.tgz

tar zxvf memcache-2.2.7.tgz

cd memcache-2.2.7/

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

cd ../

2：安装eaccelerator-eaccelerator-42067ac

wget http://down.yunwei8.com/soft/linux/eaccelerator-eaccelerator-42067ac.tar.gz

tar zxvf eaccelerator-eaccelerator-42067ac.tar.gz

cd eaccelerator-eaccelerator-42067ac

/usr/local/php/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=/usr/local/php/bin/php-config

make && make install

cd ../

3：安装PDO_MYSQL-1.0.2

建立软连接否则会报错

ln -s /usr/local/mysql/include/* /usr/local/include/

wget http://down.yunwei8.com/soft/linux/PDO_MYSQL-1.0.2.tgz

tar zxvf PDO_MYSQL-1.0.2.tgz

cd PDO_MYSQL-1.0.2/

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql

make && make install

cd ../

4：安装ImageMagick

wget http://down.yunwei8.com/soft/linux/ImageMagick-6.8.0-2.tar.gz

tar zxvf ImageMagick-6.8.0-2.tar.gz

cd ImageMagick-6.8.0-2

./configure

make && make install

cd ../

5：安装imagick-3.1.0RC2

wget http://down.yunwei8.com/soft/linux/imagick-3.1.0RC2.tgz

tar zxvf imagick-3.1.0RC2.tgz

cd imagick-3.1.0RC2

/usr/local/php/bin/phpize

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

cd ../

第六部分：配置php

1：修改php.ini文件

vi /usr/local/php/etc/php.ini

查找

; extension_dir = "./"

修改为

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/"

并在此行后增加以下几行，然后保存：

extension = "memcache.so"

extension = "pdo_mysql.so"

extension = "imagick.so"

查找

; output_buffering 

; Default Value: Off

修改为

output_buffering

Default Value: on

查找

;cgi.fix_pathinfo=1

修改为

cgi.fix_pathinfo=1，防止Nginx文件类型错误解析漏洞。

2：配置eAccelerator加速PHP：

mkdir -p /tmp/eaccelerator_cache

vi /usr/local/php/etc/php.ini

按shift+g键跳到配置文件的最末尾，加上以下配置信息：

[eaccelerator]

zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/eaccelerator.so"

eaccelerator.shm_size="64"

eaccelerator.cache_dir="/tmp/eaccelerator_cache"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="3600"

eaccelerator.shm_prune_period="3600"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

3：php5.4安装Zend Guard Loader

php5.4安装Zend Guard Loader方法一样，只是下载路径变了而已

wget http://downloads.zend.com/guard/6.0.0/ZendGuardLoader-70429-PHP-5.4-linux-glibc23-x86_64.tar.gz

tar -zxvf ZendGuardLoader-70429-PHP-5.4-linux-glibc23-x86_64.tar.gz

解压出来会看到ZendGuardLoader.so 这个模块

添加到php.ini

路径按照自己的改一下

zend_extension = "/liang/ZendGuardLoader-70429-PHP-5.4-linux-glibc23-x86_64/php-5.4.x/ZendGuardLoader.so"

在重启php-fpm即可。

4：安装xcache-3.0.4.tar.gz优化php5.4　和eaccelerator 类似选其中一个安装。我更喜欢eaccelerator。

方法：

[root@ip-10-210-151-13 liang]# wget http://xcache.lighttpd.net/pub/Releases/3.0.4/xcache-3.0.4.tar.gz

[root@ip-10-210-151-13 liang]# tar -zxvf xcache-3.0.4.tar.gz 

[root@ip-10-210-151-13 liang]# cd xcache-3.0.4

[root@ip-10-210-151-13 xcache-3.0.4]# /usr/local/php/bin/phpize 

[root@ip-10-210-151-13 xcache-3.0.4]# ./configure --enable-xcache --with-php-config=/usr/local/php/bin/php-config

[root@ip-10-210-151-13 xcache-3.0.4]# echo $?

0

[root@ip-10-210-151-13 xcache-3.0.4]# make && make install 

5：创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：

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

vi /usr/local/server/php/etc/php-fpm.conf

复制以下代码

[global]

pid = run/php-fpm.pid

error_log = log/php-fpm.log

log_level = notice

emergency_restart_threshold = 10

emergency_restart_interval = 1m

process_control_timeout = 5s

daemonize = yes

[www]

listen.owner = nobody

listen.group = nobody

listen.mode = 0666

user = www

group = www

pm = static

pm.max_children = 128

pm.start_servers = 20

pm.min_spare_servers = 5

pm.max_spare_servers = 35

pm.max_requests = 4096

request_terminate_timeout = 0

request_slowlog_timeout = 3

slowlog = log/php-fpm.log.slow

rlimit_files = 65535

rlimit_core = 0

chroot = 

chdir = 

catch_workers_output = yes

php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f [email protected]

php_flag[display_errors] = off

--------------------------------------------------------------华丽分割线--------------------------------------------------------------

特别注释(kernel.shmmax = 128000000 syscatl -p )

php.ini中设置的eAccelerator，eaccelerator.shm_size="64"，解释：eaccelerator可使用的共享内存大小(单位为MB)，即64M

在Linux下，单个进程的最大内存使用量受/proc/sys/kernel/shmmax中设置的数字限制(单位为字节) /proc/sys/kernel/shmmax = 33554432 （32M）

临时更改该值：

echo 128000000 > /proc/sys/kernel/shmmax

或者

vi /etc/sysctl.conf

kernel.shmmax = 128000000 syscatl -p

使配置立即生效：

/sbin/sysctl -p

vim /etc/rc.local

添加ulimit -SHn 65535

第八部分：将php-fpm 作为服务运行

cp /soft/php-5.4.8/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm 

chmod 755 /etc/init.d/php-fpm 

chkconfig --add php-fpm 

chkconfig --level 345 php-fpm on

服务方式启动php-fpm 

service php-fpm start

第九部分：修改nginx，支持php

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

找到并修改以下代码

location ~ \.php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME /web/www$fastcgi_script_name;

include fastcgi_params;

}

提供一份完整的nginx.conf配置文件(仅供参考)
