centos下升级php到5.6

今天正好用空把php环境升级到5.6版本，首先我之前的环境是源码包编译的lnmp环境

首先到php官方网站上下载一个php5.6的tar包，放到机器上面后，开始安装，安装前先将nginx，mysql，php-fpm都关掉，

然后将/usr/local/php这个目录删除或者改名

> tar -zxf php-5.6.8.tar.gz
>cd php-5.6.8
>./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-fpm --enable-mbstring --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext
##编译完成后，开始安装
>make ZEND_EXTRA_LIBS=‘-liconv‘
>make install

等安装完成后就差不多可以了，然后将配置文件拷贝好，

>cp php.ini-production /usr/local/php/etc/php.ini
>cp /usr/local/php/etc/php-fpm.conf.default  /usr/local/php/etc/php-fpm.conf

将/usr/local/php/etc/php-fpm.conf编辑成如下
pid = /usr/local/php/var/run/php-fpm.pid
error_log = /usr/local/php/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php-cgi.sock
listen.backlog = -1
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode = 0666
user = www
group = www
pm = dynamic
pm.max_children = 20
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 6
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log

//nginx中的配置也要对应匹配行啊
location ~ [^/]\.php(/|$)                        {    try_files $uri =404;
 fastcgi_pass  unix:/tmp/php-cgi.sock;  fastcgi_index index.php;
 include fastcgi.conf;
}

将各个服务都重新启动，就ok啦
