二、安装PHP 5.2.14（FastCGI模式）【LNMP安装 】

1、编译安装PHP 5.2.14所需的支持库：

注意：下面的libiconv比如装在/usr/local下因为php在make会需要

tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./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/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

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：

引用

[client]
character-set-server = utf8
port    = 3306
socket  = /tmp/mysql.sock

[mysqld]
character-set-server = utf8
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
user    = mysql
port    = 3306
socket  = /tmp/mysql.sock
basedir = /usr/local/webserver/mysql
datadir = /data0/mysql/3306/data
log-error = /data0/mysql/3306/mysql_error.log
pid-file = /data0/mysql/3306/mysql.pid
open_files_limit    = 10240
back_log = 600
max_connections = 5000
max_connect_errors = 6000
table_cache = 614

thread_cache_size = 300
#thread_concurrency = 8
query_cache_size = 512M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 3
log-slave-updates
log-bin = /data0/mysql/3306/binlog/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 1G
relay-log-index = /data0/mysql/3306/relaylog/relaylog
relay-log-info-file = /data0/mysql/3306/relaylog/relaylog
relay-log = /data0/mysql/3306/relaylog/relaylog
expire_logs_days = 30
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M
myisam_max_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover

interactive_timeout = 120
wait_timeout = 120

skip-name-resolve
#master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

#master-host     =   192.168.1.2
#master-user     =   username
#master-password =   password
#master-port     =  3306

server-id = 1

innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 512M
innodb_data_file_path = ibdata1:256M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 8
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 128M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
innodb_file_per_table = 0

#log-slow-queries = /data0/mysql/3306/slow.log
#long_query_time = 10

[mysqldump]
quick
max_allowed_packet = 32M

　　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12345678接下来的步骤会创建）：

#!/bin/sh

mysql_port=3306
mysql_username="admin"
mysql_password="12345678"

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 | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
   kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | 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|stop|restart|kill}\n"
fi

注意：如果上面报错语法错误

｛

注释掉function_kill_mysql方法和调用

｝

　　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（12345678）：

GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';

　　⑨、（可选）停止MySQL：

/data0/mysql/3306/mysql stop

　　3、编译安装PHP（FastCGI模式）

tar zxvf php-5.2.14.tar.gz
gzip -cd php-5.2.14-fpm-0.5.14.diff.gz | patch -d php-5.2.14 -p1
cd php-5.2.14/
./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 ../

注意： 如果配置php报错，且机器是64位系统：

｛

1.如果提示"configure: error: libjpeg.(a|so) not found"错误

所以这里我们需要复制一份libjpeg.so到/usr/lib/目录里才可以.再次执行./configure命令即可.

cp -frp /usr/lib64/libjpeg.* /usr/lib/

2.注意过程中还会提示" Configure: error: libpng.(also) not found."错误,解决办法和上面的一样.

cp -frp /usr/lib64/libpng* /usr/lib/

3.如果提示"configure: error: Cannot find ldap libraries in /usr/lib."的话.

cp -frp /usr/lib64/libldap* /usr/lib/

4.如果提示：/usr/bin/ld: cannot find -liconv

需要查看是否安装了libiconv 和是否在/usr/local下。且/usr/lib 下存在libiconv.so文件，如果不存在需要查找libiconv.so到/usr/lib下。

说明:

通过上面的搜索其实就知道一些原因了,configure一般的搜索编译路径为/usr/lib/下,因为php默认就在/usr/lib/下找相关库文件,而x64机器上是在:/usr/lib64.这时你就可以直接把需要的库文件从/usr/lib64中拷贝到/usr/lib/中去就可以了.

｝

上面的make之后要运行make install,而且如果是64位操作系统 则可能报错。

如果报错：缺少libicon.so.2 那么只需要更改/etc/ld.so.conf 增加一行: /usr/local/lib

然后运行：/sbin/sdconfig

如果继续报错：/usr/lib64/mysqlclient.so is empty 那么则需要删除这个空文件，并复制/usr/local/webserver/mysql/lib/mysqlclient.so文件过来

继续执行/sbin/sdconfig

　　4、编译安装PHP5扩展模块

tar zxvf memcache-2.2.5.tgz
cd memcache-2.2.5/
/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-6.5.1-2/
./configure
make
make install
cd ../

tar zxvf imagick-2.3.0.tgz
cd imagick-2.3.0/
/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 = "memcache.so"
　　extension = "pdo_mysql.so"
　　extension = "imagick.so"

　　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 = "memcache.so"\nextension = "pdo_mysql.so"\nextension = "imagick.so"\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.so"
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blog.s135.com和 www.s135.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）：

<?xml version="1.0" ?>

</configuration>

　　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

　　注：/usr/local/webserver/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
