PHP5安裝

• 進到src目錄下 cd /usr/local/src
• 下載PHP5源碼包wget http://cn2.php.net/distributions/php-5.6.37.tar.gz
• 解壓下載的文件 tar -zxvf php-5.6.37.tar.gz
• 進入文件目錄 cd php-5.6.37
• configure ./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-zlib-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl-dir=/usr/include/openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif
• 查看報錯信息

checking for xml2-config path… 
configure: error: xml2-config not found. Please check your libxml2 installation.

• 解決辦法以下，完成後再執行configure

yum install libxml2-devel -y 
yum install libxml2 -y

• 查看報錯信息

configure:error: cannot find OpenSSL's <evp'h>

• 解決以下，完成後再執行configure時將--with-openssl 改成--with-openssl-dir=/usr/include/openssl。或者不更改命令，直接執行yum install -y openssl-devel 也能夠。

export PHP_OPENSSL_DIR=yes

• 查看報錯信息

configure:error:please reinstall the BZip2 distribution

• 解決以下，完成後繼續configure

yum install bzip2-devel -y

• 查看報錯信息

configure:error:jpeglib.h not found

• 解決以下，完成後繼續configure

yum install libjpeg-devel -y

• 查看報錯信息

png.h  not found

• 解決後繼續configure

yum install libpng-devel

• 查看報錯信息

freetype-config not found

• 解決後繼續configure

yum install freetype-devel -y

• 查看報錯信息

mcrypt.h not found please reinstall libmcrypt

• 解決後繼續configure

yum install libmcrypt-devel -y

• 出現這個界面就能夠編譯安裝了
• make && make install
• 編譯安裝完以後須要拷貝一個文件作配置文件 ，源文件是在/usr/local/src/php-5.6.37下 ，cp php.ini-development /usr/local/php/etc/php.ini
• 查看是否加載配置文件，該命令能夠查看PHP信息，包括編譯參數，configure路徑等。

/usr/local/php/bin/php -i |less

安裝PHP 7

PHP7和PHP5的安裝大同小異

• 進入/usr/local/src目錄

• wget http://cn2.php.net/distributions/php-7.1.20.tar.bz2

• tar jxvf php-7.1.20.tar.bz2

• cd php-7.1。20

• ./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache/bin/apxs --with-config-file-path=/usr/local/php7/etc --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif

• 由於以前裝過PHP5，不少包已經安裝了，因此這一步通常不會報錯。

Thank you for using PHP.

• make&&make install 編譯安裝
• ls /usr/local/apache2.4/modules/libphp7.so

[root@localhost php-7.1.20]# cd /usr/local/apache/modules/
[root@localhost modules]# ls
httpd.exp             mod_authn_dbm.so        mod_cache.so          mod_headers.so              mod_proxy_ajp.so       mod_ratelimit.so         mod_socache_shmcb.so
libphp5.so

• cp php.ini-production /usr/local/php7/etc/php.ini
• 安裝完成後，能夠使用/usr/local/apache2.4/bin/apachectl -M 查看加載的模塊，能夠看到7和5都被加載了。-

[root@localhost php-7.1.20]# /usr/local/apache/bin/apachectl -M |grep php
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
 php5_module (shared)
 php7_module (shared)

• 當一臺機器上面裝的既有5又有7的時候，若是想讓Apache啓動時加載7，就在配置文件中將5那一行註釋掉 vi /usr/local/apache/conf/httpd.conf

#LoadModule php5_module        modules/libphp5.so
LoadModule php7_module        modules/libphp7.so

註釋掉5後發現再也不加載PHP5了。

[root@localhost php-7.1.20]# /usr/local/apache/bin/apachectl -M |grep php
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
