PHP安装

1操作系统
cat /etc/redhat-release
CentOS release 6.6 (Final)
uname -r
2.6.32-504.el6.x86_64

2 安装前准备工作
2.1 下载阿里yum源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
下载163yum源
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo -O /etc/yum.repos.d/CentOS-163.repo

注：LNMP 环境分为 Nginx+PHP+MySQL在同一主机上与Nginx+PHP在一台主机 MySQL在一台单独的主机上部署
2.2 解决依赖关系
yum -y install zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel libmcrypt-devel mcrypt mhash-devel
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar xf libiconv-1.14.tar.gz
cd libiconb-1.14
./configure --prefix=/usr/local/libiconv
make && make install

下面的部署方案为Nginx+PHP在一台主机 MySQL在一台单独的主机上部署
tar xf php-5.5.38.tar.gz
cd php-5.5.38

./configure \
 --prefix=/application/php5.5.38 \
 --with-mysql=mysqlnd \
 --with-mysqli=mysqlnd \
 --with-pdo-mysql=mysqlnd \
 --with-iconv-dir=/usr/local/libiconv \
 --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-soap \
 --enable-short-tags \
 --enable-static \
 --with-xsl \
 --with-fpm-user=nginx \
 --with-fpm-group=nginx \
 --enable-ftp \
 --enable-opcache=no

–enable-opcache开启php自带zendopcache加速模块可以酌情安装 PHP 5.5之后内建
–with-mysql=/application/mysql 表示指定mysql安装路径，如果没有安装mysql包，也可以不单独安装，这样的情况以，–with-mysql=mysqlnd代替

make && make install

make最后的正确提示
#Build complete.
#Don’t forget to run ‘make test’.
make install
#make install 正确结束后的最后两行内容如下
#/root/tools/php5.5.38/build/shtool install -c ext/phar/phar.phar /application/php5.5.38/bin
#ln -s -f /application/php5.5.38/bin/phar.phar /application/php5.5.38/bin/phar
#Installing PDO headers: /application/php5.5.38/include/php/ext/pdo/

创建软连接
ln -s /application/php5.5.38/ /application/php

配置PHP引擎配置文件php.ini
cp /tools/php-5.5.38/php.ini-production /application/php/lib/php.ini

配置PHP服务（FastCGI方式）的配置文件php-fpm.conf
cd /application/php/etc/
cp php-fpm.conf.default php-fpm.conf

启动php-fpm
/application/php/sbin/php-fpm #启动时有可能会出现下面报错
#[08-Mar-2017 20:00:18] ALERT: [pool www] pm.min_spare_servers(0) must be a positive value
#[08-Mar-2017 20:00:18] ERROR: failed to post process the configuration
#处理办法 去掉下面三行前面的;（分号）
vim /application/php/etc/php-fpm.conf
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35

或用sed命令修改
sed -i ‘s/;pm.start_servers = 20/pm.start_servers = 20/g’ /application/php/etc/php-fpm.conf
sed -i ‘s/;pm.min_spare_servers = 5/pm.min_spare_servers = 5/g’ /application/php/etc/php-fpm.conf
sed -i ‘s/;pm.max_spare_servers = 35/pm.max_spare_servers = 35/g’ /application/php/etc/php-fpm.conf

pm = dynamic #dynamic已用户访问量来开启fpm个数 static固定fpm数
pm.max_children = 50 #最大pm值 如果选择static模式 下面三个参数没有作用
pm.start_servers = 20 #初始开几个pm进程
pm.min_spare_servers = 5 #最少保持几个pm空闲进程
pm.max_spare_servers = 35 #最大空闲进程

添加php-fpm 到/etc/init.d中
cp /tools/php-5.5.38/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
/etc/init.d/php-fpm start

启动后检查状态
/application/php/sbin/php-fpm
lsof -i :9000

Nginx+PHP+MySQL在同一主机上
tar xf php-5.5.38.tar.gz
cd php-5.5.38

./configure \
 --prefix=/application/php5.5.38 \
 --with-mysql=/application/mysql \
 --with-iconv-dir=/usr/local/libiconv \
 --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-soap \
 --enable-short-tags \
 --enable-static \
 --with-xsl \
 --with-fpm-user=nginx \
 --with-fpm-group=nginx \
 --enable-ftp \
 --enable-opcache=no

make之前操作 不然会报错
ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/ #PHP指定库软连接
[root@web01 php-5.5.38]#touch ext/phar/phar.phar

make && make install

指定php使用mysql套接字
vim /application/php/lib/php.ini
977 pdo_mysql.default_socket= /application/mysql-5.6.15/tmp/mysql.sock
