搭建php
centos 6.5 64
php： 5.5.32
三.安装PHP
先配置本地yum源
安装依赖包：
yum -y install curl-devel mysql-devel libfreetype6-dev freetype-devel libpng libpng-devel openldap openldap-devel bzip2-devel db4-devel postgresql-devel net-snmp-devel libjpeg-devel libpng-devel libXpm-devel gmp-devel pspell-devel libxslt-devel libc-client-devel openldap-devel libxslt-devel libxml2-devel pcre-devel mysql-develunixODBC-devel
安装PHP所需依赖包：
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 ../
# 对共享库做符号链接
ln -s /usr/local/lib/libmcrypt.la /usr/lib64/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib64/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib64/libmcrypt.so.4
ln -sf /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib64/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib64/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib64/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib64/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib64/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib64/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libmysqlclient.so.18
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make && make install
cd ../
安装php：
tar zxvf php-5.5.13.tar.gz
cd php-5.5.13
mkdir /usr/local/php
mkdir /usr/local/php/etc
请核对一下自己的安装目录。
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc \
--with-mysql=/opt/mysql --with-mysqli=/opt/mysql/bin/mysql_config \
--with-iconv-dir --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 --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf \
--with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap \
--enable-opcache=no --without-pear --disable-fileinfo
列表如下（部分参数未得到解释）：
# 指定 php 安装目录
--prefix=/usr/local/php
# 指定php.ini位置
--with-config-file-path=/usr/local/php/etc
# mysql安装目录，对mysql的支持
--with-mysql=/usr/local/mysql
mysqli扩展技术不仅可以调用MySQL的存储过程、处理MySQL事务，而且还可以使访问数据库工作变得更加稳定。
--with-mysqli=/usr/local/mysql/bin/mysql_config
整合 apache，apxs功能是使用mod_so中的LoadModule指令，加载指定模块到 apache，要求 apache 要打开SO模块
--with-apxs2=/usr/local/apache/bin/apxs
# 选项指令 --with-iconv-dir 用于 PHP 编译时指定 iconv 在系统里的路径，否则会扫描默认路径。
--with-iconv-dir=/usr/local
#注：如果内存较大 可以去掉--disable-fileinfo
make ZEND_EXTRA_LIBS='-liconv'
make install
cp php.ini-development /usr/local/php/etc/php.ini
cd ../
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
vi /usr/local/php/etc/php-fpm.conf
修改
user = nobody
group = nobody
为
user = www
group = www
# 将;pid = run/php-fpm.pid前的;去掉并修改为
pid = /usr/local/php/var/run/php-fpm.pid
启动php-fpm
/usr/local/php/sbin/php-fpm
将Nginx与fpm加入自启动
vi /etc/rc.local
# 输入
ulimit -SHn 65535
/usr/local/php/sbin/php-fpm
/usr/local/nginx/sbin/nginx
编译PHP扩展模块memcache、pdo_mysql、imagick
tar zxvf memcache-3.0.8.tgz
cd memcache-3.0.8
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
cd ../
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=/opt/mysql
/usr/include/mysql 是mysql的头文件位置
ln -s /usr/include/mysql/* /usr/local/include/
make && make install
cd ../
tar zxvf ImageMagick.tar.gz
cd ImageMagick-6.5.1-2/
./configure
make && make install
cd ../
tar zxvf imagick-3.2.0RC1.tgz
cd imagick-3.2.0RC1
/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 ../
修改php.ini配置文件
vi /usr/local/php/etc/php.ini
#查找; extension_dir = "/" 将前面的;去掉并修改为
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/"
#并加入
extension=memcache.so
extension=pdo_mysql.so
extension=imagick.so
执行下面的命令使配置文件立即生效：
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
其他（可选）：
优化linux内核参数
vi /etc/sysctl.conf
在末尾增加以下内容：
# 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
安装opcache（因为PHP 5.5已经集成Zend Opcache，可以替代eaccelerator）
tar zxvf zendopcache-7.0.3.tgz
cd zendopcache-7.0.3
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
cd ../
在php.ini中加入下面配置：
[opcache]
zend_extension="/usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/opcache.so"
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1
# 使php.ini配置文件立即生效
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
常用命令：
#修改完php.ini后执行：
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
#修改完nginx.conf后执行
/usr/local/nginx/sbin/nginx -s reload
#重启mysql服务执行：
service mysqld (start|stop|restart)
ln -s /usr/local/php/bin/php /usr/bin/php
链接到/usr/bin下
同样在slave上按照上面的步骤安装。
请多指教！
