centos7 編譯安裝php5.6.27

安裝依賴，沒有libmcrypt libmcrypt-devel mcrypt mhash的話，添加擴展包，更新yum源

yum -y install epel-release yum -y update yum -y install libmcrypt libmcrypt-devel mcrypt mhash yum -y install libxml2-devel libpng-devel libjpeg-devel zlib bzip2 bzip2-devel  libtool-ltdl-devel pcre-devel openssl-devel freetype-devel libcurl-devel icu  perl-libintl postgresql libicu-devel

cd /usr/local/src/ wget http://cn2.php.net/distributions/php-5.6.27.tar.gz tar -zxvf php-5.6.27.tar.gz cd php-5.6.27/

安裝php

./configure  --prefix=/usr/local/php5.6.27  --with-config-file-path=/usr/local/php5.6.27/etc/  --enable-inline-optimization  --enable-shared  --enable-opcache  --enable-fpm  --with-fpm-user=php  --with-fpm-group=web  --with-mysql=mysqlnd  --with-mysqli=mysqlnd  --with-pdo-mysql=mysqlnd  --with-gettext  --enable-mbstring  --with-iconv  --with-mcrypt  --with-mhash  --with-openssl  --enable-bcmath  --enable-soap  --with-libxml-dir  --enable-pcntl  --enable-shmop  --enable-sysvmsg  --enable-sysvsem  --enable-sysvshm  --enable-sockets  --enable-intl  --with-curl  --with-zlib  --enable-zip  --with-bz2  --enable-xml  --with-pcre-dir  --with-gd  --enable-static  --enable-wddx  --with-xmlrpc  --with-libdir=/usr/lib64  --with-jpeg-dir=/usr/lib64  --with-freetype-dir=/usr/lib64  --with-png-dir=/usr/lib64 make && make install

配置 PHP

cp php.ini-development /usr/local/php5.6.27/etc/php.ini cp /usr/local/php5.6.27/etc/php-fpm.conf.default /usr/local/php5.6.27/etc/php-fpm.conf

創建開機啟動

vi /lib/systemd/system/php-fpmd.service

[Unit] Description=The PHP FastCGI Process Manager After=network.target [Service] Type=forking PIDFile=/run/php-fpm.pid ExecStart=/usr/local/php5.6.27/sbin/php-fpm --daemonize -g /run/php-fpm.pid ExecReload=/bin/kill -USR2 $MAINPID ExecStop=/bin/kill -SIGINT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target

PS：如果yum安裝，php-fpm.service文件的內容

[Unit] Description=The PHP FastCGI Process Manager After=syslog.target network.target [Service] Type=notify PIDFile=/run/php-fpm.pid EnvironmentFile=/etc/sysconfig/php-fpm ExecStart=/usr/sbin/php-fpm --nodaemonize ExecReload=/bin/kill -USR2 $MAINPID PrivateTmp=true [Install]

WantedBy=multi-user.target

添加運行權限

chmod +x /lib/systemd/system/php-fpmd.service

設置開機自啟動

systemctl enable php-fpmd.service

運行
