php5.3.10的安装

下面以最新的php-5.3.10为例进行安装。



wget <a href="http://cn.php.net/distributions/php-5.3.10.tar.gz">http://cn.php.net/distributions/php-5.3.10.tar.gz</a><br />

tar -zxvf php-5.3.10.tar.gz
cd php-5.3.10
./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-iconv-dir –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir –enable-xml –disable-rpath –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fpm –enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-ldap –with-ldap-sasl –with-xmlrpc –enable-zip –enable-soap

上面的具体参数可以使用./configure --help查看



make ZEND_EXTRA_LIBS='-liconv'<br />

make test
make && make install   (此处最好分开做,因为make的时候会有报错出现。)

我在上面的make时就报了下面的错误



root/source/php-5.3.10/sapi/cli/php: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory<br />

make: *** [ext/phar/phar.php] Error 127

解决办法是(我的mysql安装目录是/usr/local/msyql,这个视自己的mysql安装路径而定。)<br />

ln -s /usr/local/mysql/lib/libmysqlclient.so.18  /usr/lib/
64位系统应使用下面的这行
ln -s /usr/local/mysql/lib/libmysqlclient.so.18  /usr/lib64/

&nbsp;



若报下面的错,就是在编绎mysql的时候没有加上mysqli这一项,把下面标红的那部分取消掉,重新编绎就行了。



make: *** [ext/mysqli/mysqli.lo] Error 1<br />

./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-iconv-dir –with-freetype-dir –with-jpeg-dir –with-png-dir –with-zlib –with-libxml-dir –enable-xml –disable-rpath –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –with-curl –with-curlwrappers –enable-mbregex –enable-fpm –enable-mbstring –with-mcrypt –with-gd –enable-gd-native-ttf –with-openssl –with-mhash –enable-pcntl –enable-sockets –with-ldap –with-ldap-sasl –with-xmlrpc –enable-zip –enable-soap

另外,也有报下面错的可能。该问题有可能是没有安装iconv这个编码转换的包,也有可以装了,但是仍有这个错。



sapi/cli/php: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory<br />

make[1]: *** [install-pear-installer] Error 127
make: *** [install-pear] Error 2

find / -name libiconv.so.2在/usr/lib/libiconv.so.2位置发现libiconv已经安装。<br />

于是运行/sbin/ldconfig,再重新编译,不再报上面的错。ldconfig用于加载最新编绎过的包。

&nbsp;



<span style="color:#e56600;">注:上面很多需要的包我都是通过</span><span style="color:#e56600;">通过./configure --prefix=/usr --libdir=/usr/lib --sysconfdir=/etc参数编绎</span><span style="color:#e56600;">。这样其在默认的目录就能找到该包了。</span>



&nbsp;



cp php.ini-production /usr/local/php/etc/php.ini<br />

cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
cp sapi/fpm/php-fpm.conf /usr/local/php/etc/php-fpm.conf

修改php.ini文件和php-fpm文件中参数,可以手动更改也可以用下面的sed命令更改



sed -i 's#short_open_tag = Off#short_open_tag = On#g' /usr/local/php/etc/php.ini<br />

sed -i ‘s#;pid = run/php-fpm.pid#pid = run/php-fpm.pid#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.max_children = 5#pm.max_children = 32#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.start_servers = 2#pm.start_servers = 16#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.min_spare_servers = 1#pm.min_spare_servers = 8#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#pm.max_spare_servers = 3#pm.max_spare_servers = 32#g’ /usr/local/php/etc/php-fpm.conf
sed -i ‘s#;pm.max_requests = 500#pm.max_requests = 120#g’ /usr/local/php/etc/php-fpm.conf 

&nbsp;



&nbsp;关于php-fpm几个重要参数的调整方面具体可以参看我的另一篇日志:<a href="https://www.361way.com/php-fpm/890.html">https://www.361way.com/php-fpm/890.html</a>&nbsp; 另外php官方也给出了其中所有参数项的解释说明,具体见<a href="http://www.php.net/manual/en/install.fpm.configuration.php">http://www.php.net/manual/en/install.fpm.configuration.php</a>



&nbsp;



设置开机启动



chmod 755 /etc/init.d/php-fpm<br />

chkconfig –add php-fpm
/etc/init.d/php-fpm start

至此,php的安装完毕。



&nbsp;



最后可以再安装一些php的扩展包和开户php加速(具体软件包可以视网上的最新版进行安装):



tar zxvf memcache-2.2.5.tgz<br />

cd memcache-2.2.5/
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar jxvf eaccelerator-0.9.6.1.tar.bz2<br />

cd eaccelerator-0.9.6.1/
/usr/local//php/bin/phpize
./configure –enable-eaccelerator=shared –with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz<br />

cd PDO_MYSQL-1.0.2/
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config –with-pdo-mysql=/usr/local/mysql
make
make install
cd ../

tar zxvf ImageMagick.tar.gz<br />

cd ImageMagick-6.5.1-2/
./configure
make
make install
cd ../

tar zxvf imagick-2.3.0.tgz<br />

cd imagick-2.3.0/
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config
make
make install
cd ../

修改php.ini文件<br />

手工修改:查找/usr/local/php/etc/php.ini中的extension_dir = “./”
修改为extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/”
并在此行后增加以下几行,然后保存:
extension = “memcache.so”
extension = “pdo_mysql.so”
extension = “imagick.so”

再查找output_buffering = Off<br />

修改为output_buffering = On

再查找; cgi.fix_pathinfo=0<br />

修改为cgi.fix_pathinfo=0,防止Nginx文件类型错误解析漏洞。

&nbsp;



配置eAccelerator加速PHP:<br />

mkdir -p /opt/webserver/eaccelerator_cache
vi /usr/local/php/etc/php.ini

在php.ini配置文件的最末尾,加上以下配置信息:<br />

[eaccelerator]
zend_extension=”/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so”
eaccelerator.shm_size=”64″
eaccelerator.cache_dir=”/opt/webserver/eaccelerator_cache”
eaccelerator.enable=”1″
eaccelerator.optimizer=”1″
eaccelerator.check_mtime=”1″
eaccelerator.debug=”0″
eaccelerator.filter=””
eaccelerator.shm_max=”0″
eaccelerator.shm_ttl=”3600″
eaccelerator.shm_prune_period=”3600″
eaccelerator.shm_only=”0″
eaccelerator.compress=”1″
eaccelerator.compress_level=”9″

<span style="color:#e53333;">本文中其实关于加速的部分是错误的,因为当时我测试时,只是把php安装好以后,后面的</span><span style="color:#e53333;">eaccelerator加速部分是直接复制的原来的安装部分,并未进行测试,后来因为生产环境的需要,进行安装时,发现</span><span style="color:#e53333;">eaccelerator不支持最新的php5.3.10。于是换成更新速度最快的xcache发现支持。</span>
