系统有个php5.5.14 现在需要再安装个php5.6.31

1.php.net 下载php5.6.31并安装

tar zxvf php-5.6.31.tar.gz

cd php-5.6.31

./configure --prefix=/usr/local/php56 --with-config-file-path=/usr/local/php56/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir=/usr/local/freetype --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-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 --with-gettext --disable-fileinfo --enable-opcache --enable-intl --with-xsl	

遇到一些错误  参考http://www.bkjia.com/PHPjc/1008013.html

configure: error:  Unable to detect ICU prefix or no failed. Please verify ICU install prefix and make sure icu-config works.

安装 libicu-devel

yum -y install libicu-devel

configure: error: xslt-config not found. Please reinstall the libxslt >= 1.1.0 distribution

安装  libxslt-devel
yum -y install libxslt-devel

注意一下make
make ZEND_EXTRA_LIBS='-liconv'

make install

2
拷贝配置文件
cp -R ./sapi/fpm/php-fpm.conf /usr/local/php56/etc/php-fpm.conf
cp php.ini-development /usr/local/php56/etc/php.ini
cp  /etc/init.d/php-fpm  /etc/init.d/php-fpm56
php-fpm56修改一下PHP的目录就可以了  

4.配置php-fpm 修改php-fpm.conf的侦听端口为9001，因为主版本5.5.14是侦听9000。  killall php-fpm56

/usr/local/php56/etc/php-fpm.conf

listen = 127.0.0.1:9001  

配置PHP.ini

# php extensions
echo "Modify php.ini......"
sed -i 's/post_max_size =.*/post_max_size = 50M/g' /usr/local/php56/etc/php.ini
sed -i 's/upload_max_filesize =.*/upload_max_filesize = 50M/g' /usr/local/php56/etc/php.ini
sed -i 's/;date.timezone =.*/date.timezone = PRC/g' /usr/local/php56/etc/php.ini
sed -i 's/short_open_tag =.*/short_open_tag = On/g' /usr/local/php56/etc/php.ini
sed -i 's/;cgi.fix_pathinfo=.*/cgi.fix_pathinfo=0/g' /usr/local/php56/etc/php.ini
sed -i 's/max_execution_time =.*/max_execution_time = 300/g' /usr/local/php56/etc/php.ini
sed -i 's/disable_functions =.*/disable_functions = passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server/g' /usr/local/php56/etc/php.ini



echo "Creating new php-fpm configure file..."
    cat >/usr/local/php56/etc/php-fpm.conf<<EOF
[global]
pid = /usr/local/php56/var/run/php-fpm.pid
error_log = /usr/local/php56/var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php56-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 = 10
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/php56slow.log
EOF

fastcgi_pass 127.0.0.1:9001;


下面备注一下需要装一些库

extension=yaf.so
extension=memcache.so
extension=memcached.so
extension=redis.so
extension=bz2.so
