深蓝色为shell命令，默认黑色为vi编辑内容，##后为注释

---------------------------------------------------------------

1.定时校正服务器时间

##修改系统的时区
rm -rf /etc/localtime
ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
yum install ntp
crontab -e
##加入一行：
*/15 * * * * ntpdate 210.72.145.44
## 210.72.145.44 为中国国家授时中心服务器地址。

2.停止网卡对ipv6的支持

##修改相应配置文件，添加如下行到文尾：
vi /etc/modprobe.conf
alias net-pf-10 off
alias ipv6 off
##上述操作重启后生效

3.让系统运行在init 3的模式下

vi /etc/inittab
##表示当前缺省运行级别为5(initdefault)；
id:5:initdefault: ← 将此处的5修改为3,3为字符模式。

4.禁用selinux （建议开启，但权限需要额外的配置）

vi /etc/selinux/config
SELINUX=disable 禁用SeLinux
SELINUX=enforcing 使用SeLinux

5.利用CentOS Linux系统自带的yum命令安装、升级所需的程序库
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

二、安装PHP 5.2.17（FastCGI模式）
1、编译安装PHP 5.2.17所需的支持库：

tar zxvf libiconv-1.14.tar.gz
cd libiconv-1.14/
./configure --prefix=/usr/local
make
make install
cd ../

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 ../../

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/ /usr/lib/
ln -s /usr/local/lib/ /usr/lib/
ln -s /usr/local/lib/.4 /usr/lib/.4
ln -s /usr/local/lib/.4.4.8 /usr/lib/.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../

#######################################
--------------------------------------------------------------------------------

2、编译安装MySQL 5.5.3-m3

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.5.3-m3.tar.gz
cd mysql-5.5.3-m3/
./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cd ../

--------------------------------------------------------------------------------

附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下几步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。

①、创建MySQL数据库存放目录

mkdir -p /data0/mysql/3306/data/
mkdir -p /data0/mysql/3306/binlog/
mkdir -p /data0/mysql/3306/relaylog/
chown -R mysql:mysql /data0/mysql/

②、以mysql用户帐号的身份建立数据表：

/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql

③、创建my.cnf配置文件：

vi /data0/mysql/3306/my.cnf

输入以下内容：

#######################################

④、创建管理MySQL数据库的shell脚本：

vi /data0/mysql/3306/mysql

输入以下内容（这里的用户名admin和密码moneypy接下来的步骤会创建）：
#######################################

#!/bin/sh  
 
mysql_port=3306  
mysql_username="admin" 
mysql_password="moneypy" 
 
function_start_mysql()  
{  
    printf "Starting MySQL...\n" 
    /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &  
}  
 
function_stop_mysql()  
{  
    printf "Stoping MySQL...\n" 
    /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown  
}  
 
function_restart_mysql()  
{  
    printf "Restarting MySQL...\n" 
    function_stop_mysql  
    sleep 5  
    function_start_mysql  
}  
 
function_kill_mysql()  
{  
    kill -9 $(ps -ef &#124; grep 'bin/mysqld_safe' &#124; grep ${mysql_port} &#124; awk '{printf $2}')  
    kill -9 $(ps -ef &#124; grep 'libexec/mysqld' &#124; grep ${mysql_port} &#124; awk '{printf $2}')  
}  
 
if [ "$1" = "start" ]; then 
    function_start_mysql  
elif [ "$1" = "stop" ]; then 
    function_stop_mysql  
elif [ "$1" = "restart" ]; then 
function_restart_mysql  
elif [ "$1" = "kill" ]; then 
function_kill_mysql  
else 
    printf "Usage: /data0/mysql/${mysql_port}/mysql {start&#124;stop&#124;restart&#124;kill}\n" 
fi

#######################################
⑤、赋予shell脚本可执行权限：

chmod +x /data0/mysql/3306/mysql

⑥、启动MySQL：

/data0/mysql/3306/mysql start

⑦、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）：

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

⑧、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（moneypy）：

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY 'moneypy';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY 'moneypy';

⑨、（可选）停止MySQL：

/data0/mysql/3306/mysql stop

--------------------------------------------------------------------------------

3、编译安装php-5.2.17（FastCGI模式）

tar zxvf php-5.2.17.tar.gz
gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1
cd php-5.2.17/
./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --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
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-dist /usr/local/webserver/php/etc/php.ini
cd ../

--------------------------------------------------------------------------------

4、编译安装PHP5扩展模块
#######################################

tar zxvf memcache-2.2.6.tgz
cd memcache-2.2.6/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2
cd eaccelerator-0.9.6.1/
/usr/local/webserver/php/bin/phpize
./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql
make
make install
cd ../

tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.7.2-9/
./configure
make
make install
cd ../

tar zxvf imagick-3.0.1.tgz
cd imagick-3.0.1/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

#######################################

5、修改php.ini文件
手工修改：查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/usr/local/webserver/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 = ""
extension = "pdo_mysql.so"
extension = ""

再查找output_buffering = Off
修改为output_buffering = On

再查找; cgi.fix_pathinfo=0
修改为cgi.fix_pathinfo=0，防止Nginx文件类型错误解析漏洞。

自动修改：若嫌手工修改麻烦，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/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = ""\nextension = "pdo_mysql.so"\nextension = ""\n#' /usr/local/webserver/php/etc/php.ini
sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /usr/local/webserver/php/etc/php.ini
sed -i "s#; cgi.fix_pathinfo=0#cgi.fix_pathinfo=0#g" /usr/local/webserver/php/etc/php.ini

#######################################

6、配置eAccelerator加速PHP：

mkdir -p /usr/local/webserver/eaccelerator_cache
vi /usr/local/webserver/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：

引用

#######################################

[eaccelerator]
zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="/usr/local/webserver/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"

#######################################

--------------------------------------------------------------------------------

7、创建www用户和组，以及供moneypy.blog.51cto.com和www.51cto.com两个虚拟主机使用的目录：

/usr/sbin/groupadd www
/usr/sbin/useradd -g www www
mkdir -p /data0/htdocs/blog
chmod +w /data0/htdocs/blog
chown -R www:www /data0/htdocs/blog
mkdir -p /data0/htdocs/www
chmod +w /data0/htdocs/www
chown -R www:www /data0/htdocs/www

8、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）：
在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：

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

输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：

9、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为128（如果服务器内存小于3GB，可以只开启64个进程），用户为www：

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

--------------------------------------------------------------------------------

三、安装Nginx 1.0.8
1、安装Nginx所需的pcre库：

tar zxvf pcre-8.13.tar.gz
cd pcre-8.13/
./configure
make && make install
cd ../

2、安装Nginx

tar zxvf nginx-1.0.8.tar.gz
cd nginx-1.0.8/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module
make && make install
cd ../

3、创建Nginx日志目录

mkdir -p /data1/logs
chmod +w /data1/logs
chown -R www:www /data1/logs

4、创建Nginx配置文件
①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：

rm -f /usr/local/webserver/nginx/conf/nginx.conf
vi /usr/local/webserver/nginx/conf/nginx.conf

输入以下内容：

5、启动Nginx

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

--------------------------------------------------------------------------------

四、配置开机自动启动Nginx + PHP + mysql

vi /etc/rc.local

在末尾增加以下内容：

引用

ulimit -SHn 65535
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx
/data0/mysql/3306/mysql start

--------------------------------------------------------------------------------

五、优化Linux内核参数

vi /etc/sysctl.conf

在末尾增加以下内容：

引用

#######################################

# 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_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

--------------------------------------------------------------------------------

六、在不停止Nginx服务的情况下平滑变更Nginx配置
1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：

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

如果屏幕显示以下两行信息，说明配置文件正确：
the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok
the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully

2、平滑重启：
①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：

/usr/local/webserver/nginx/sbin/nginx -s reload

②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：

ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

屏幕显示的即为Nginx主进程号，例如：
6302
这时，执行以下命令即可使修改过的Nginx配置文件生效：

kill -HUP 6302

或者无需这么麻烦，找到Nginx的Pid文件：

kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

--------------------------------------------------------------------------------

七、编写每天定时切割Nginx日志的脚本
1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh

vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

输入以下内容：

引用

#######################################

#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/usr/local/webserver/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log
kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`

#######################################

2、设置crontab，每天凌晨00:00切割nginx访问日志

crontab -e

输入以下内容：

引用

00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
