1、去官网下载镜像文件: http://php.net/get/php-7.2.3.tar.gz/from/a/mirror
找香港的下载:
2、 cd /usr/local/src 所有的软件源码放到这里
wget http://hk1.php.net/get/php-7.2.3.tar.gz/from/this/mirror
mv mirror php-7.2.3
cd php-7.2.3
3、开始编译:
# ./configure --prefix=/usr/local/php7 \
--with-curl \
--with-freetype-dir \
--with-gd \
--with-gettext \
--with-iconv-dir \
--with-kerberos \
--with-libdir=lib64 \
--with-libxml-dir \
--with-mysqli \
--with-openssl \
--with-pcre-regex \
--with-pdo-mysql \
--with-pdo-sqlite \
--with-pear \
--with-png-dir \
--with-xmlrpc \
--with-xsl \
--with-zlib \
--enable-fpm \
--enable-bcmath \
--enable-libxml \
--enable-inline-optimization \
--enable-gd-native-ttf \
--enable-mbregex \
--enable-mbstring \
--enable-opcache \
--enable-pcntl \
--enable-shmop \
--enable-soap \
--enable-sockets \
--enable-sysvsem \
--enable-xml \
--enable-zip
由于我原本安装好了相关库，所以我不需要再安装了，如果安装报错，就yum下。
如果配置错误，需要安装需要的模块，直接yum一并安装依赖库
# yum -y install libjpeg libjpeg-devel libpng libpng-devel \
freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel
网上很多所谓的教程都是直接：
4、# make && make install
但是这样可能会报错：make: *** [sapi/cli/php] error 1
其实这样就行了：
make ZEND_EXTRA_LIBS='-liconv'
make install
5、然后搞些配置吧
# cp php.ini-production /usr/local/php7/etc/php.ini
# cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf
# cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf
# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm7
6、开机自启动：
cd /etc/init.d
vim php7-fpm
内容如下:
#! /bin/sh
#chkconfig: 2345 10 90
## vim /usr/local/php7/etc/php-fpm.conf #uncomment pid under [global] #pid = run/php-fpm.pid
## vim /etc/init.d/php7-fpm
## chmod a+x /etc/init.d/php7-fpm
## chkconfig --add php7-fpm
## chkconfig php7-fpm on
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="php-fpm7 daemon"
NAME=php-fpm
INSTALLDIR=/usr/local/php7
DAEMON=$INSTALLDIR/sbin/$NAME
CONFIGFILE=$INSTALLDIR/lib/$NAME.conf
PIDFILE=$INSTALLDIR/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/php-fpm72
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON -D || echo -n "php-fpm7 already running"
}
do_stop() {
kill -INT `cat $PIDFILE` || echo -n "php-fpm7 not running"
}
do_test() {
$DAEMON -t || echo -n "php-fpm7 can't test"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
test)
echo -n "Testing $DESC: $NAME"
do_test
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|restart|test}" >&2
exit 3
;;
esac
exit 0
7、chmod a+x /etc/init.d/php7-fpm
chkconfig --add php7-fpm
chkconfig php7-fpm on
8、service php7-fpm start
到此安装完毕
9、检查ini位置
php --ini
[root@localhost init.d]# php --ini
Configuration File (php.ini) Path: /usr/local/php7/lib
Loaded Configuration File: /usr/local/php7/lib/php.ini
Scan for additional .ini files in: (none)
Additional .ini files parsed: (none)
You have new mail in /var/spool/mail/root
10、所有的扩展路径：/usr/local/php7/lib/php/extensions/no-debug-non-zts-20170718/
11、php7.2 如果pecl install *** 不成功的话 可以通过源码phpize 安装 记得ini别错了
