当前服务器用的是军哥lnmp1.3一键包，已经装好了php5.6，在此基础上，并存一个php5.4的版本。
废话不多说直接进入主题！
编译安装php-5.4.45
下载php5.4.45源码包
|
1 2 |
cd /usr/src wget http://cn.php.net/distributions/php-5.4.45.tar.gz |
解压缩源码包
|
1 |
tar zxf php-5.4.45.tar.gz |
进入php-5.4.45目录进行编译（注意./configure里指定的路径，当前php-5.6用的/usr/local/php路径，所以我这里就把路径改成了/usr/local/php54路径，避免和php-5.6版本冲突）
|
1 |
cd php-5.4.45 |
|
1 2 3 4 5 |
./configure --prefix=/usr/local/php54 --with-config-file-path=/usr/local/php54/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-intl --with-xsl make ZEND_EXTRA_LIBS='-liconv' make install |
复制一个php.ini文件
|
1 |
cp php.ini-production /usr/local/php54/etc/php.ini |
复制php-fpm启动
|
1 2 |
cp sapi/fpm/init.d.php-fpm /etc/init.d/php54-fpm chmod +x /etc/init.d/php54-fpm |
编辑php.ini文件，修改几项参数
|
1 2 3 4 5 6 |
post_max_size = 50M upload_max_filesize = 32M date.timezone = PRC short_open_tag = On cgi.fix_pathinfo=0 max_execution_time = 300 |
修改php-fpm.conf
|
1 2 3 |
cd /usr/local/php54/etc/ cp php-fpm.conf.default php-fpm.conf vim php-fpm.conf |
直接将原有php-fpm.conf内容全部删除，复制以下文件
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
[global] pid = /usr/local/php54/var/run/php-fpm.pid error_log = /usr/local/php54/var/log/php-fpm.log log_level = notice [www] listen = /tmp/php54-cgi.sock listen.backlog = -1 listen.allowed_clients = 127.0.0.1:9001 listen.owner = www listen.group = www listen.mode = 0666 user = www group = www pm = dynamic pm.max_children = 80 pm.start_servers = 40 pm.min_spare_servers = 40 pm.max_spare_servers = 80 request_terminate_timeout = 100 request_slowlog_timeout = 0 slowlog = var/log/slow.log |
启动php54-fpm
|
1 |
/etc/init.d/php54-fpm start |
修改nginx配置，配置php
|
1 2 3 4 5 6 7 |
location ~ [^/]\.php(/|$) { try_files $uri =404; fastcgi_pass unix:/tmp/php54-cgi.sock; fastcgi_index index.php; include fastcgi.conf; } |
服务器上编辑个phpinfo.php
|
1 2 3 |
<?php phpinfo() ?> |
访问一下看看，当当当php5.4.45出现了，表示php多版本共存安装成功。
再将fastcgi_pass unix:/tmp/php54-cgi.sock;改成fastcgi_pass unix:/tmp/php-cgi.sock;又可以看到php5.6了.
PS：php.ini和php-fpm我这里只是给个示例，实际使用中，根据情况自行调整。

如果报错的话可以/tmp/php54-cgi.sock设置成666权限chmod 666 /tmp/php54-cgi.sock
