php之编译安装

　　

1. 安装所需环境

yum -y install libxml2 libxml2-devel openssl openssl-devel curl-devel libjpeg-devel libpng-devel freetype-devel libmcrypt-devel libzip-devel pcre-devel

2. 下载并安装PHP

1. 下载
wget http://cn2.php.net/distributions/php-7.3.3.tar.gz

2. 解压
tar -xzf php-7.3.3.tar.gz

3. 进入目录
cd php7.3.3

4. 编译php
./configure --prefix=/usr/local/php7 
--with-config-file-path=/usr/local/php7/etc 
--with-config-file-scan-dir=/usr/local/php7/etc/php.d --enable-mysqlnd 
--with-mysqli 
--with-pdo-mysql 
--enable-fpm 
--with-fpm-user=nginx 
--with-fpm-group=nginx 
--with-gd 
--with-iconv 
--with-zlib 
--enable-xml 
--enable-shmop 
--enable-sysvsem 
--enable-inline-optimization 
--enable-mbregex 
--enable-mbstring 
--enable-ftp --with-openssl 
--enable-pcntl 
--enable-sockets 
--with-xmlrpc 
--enable-zip 
--enable-soap 
--without-pear 
--with-gettext 
--enable-session 
--with-curl 
--with-jpeg-dir 
--with-freetype-dir 
--enable-opcache

　　编译,安装

make && make install -j2

-j: 启用两个任务

3. 配置PHP

　　1) 复制ini文件

cp php.ini-production /usr/local/php7/etc/php.ini

　　2) 配置fpm

cd /usr/src/php-7.0.0/sapi/fpm

cp init.d.php-fpm /etc/init.d/php-fpm

chmod +x /etc/init.d/php-fpm

chkconfig --add php-fpm

chkconfig php-fpm on

4. 启动服务

/etc/init.d/php-fpm start

5. 添加环境变量

vim /etc/profile

最后添加
export PATH=$PATH:/usr/local/php7/bin

马上生效
source /etc/profile

可以正常使用全局命令
php -v

　　解决:

　　

安装libiconv:
#wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.13.1.tar.gz
#tar -zxvf libiconv-1.13.1.tar.gz
#cd libiconv-1.13.1
# ./configure --prefix=/usr/local/libiconv
# make
# make install

编译PHP添加参数:
再检查php，指定 iconv的位置  --with-iconv=/usr/local/libiconv
#./configure --prefix=/usr/local/php72 --with-iconv=/usr/local/libiconv
#make
#make install

 　　

　　2. error：Please reinstall the BZip2 distribution

yum install bzip2 bzip2-devel

　　3. configure: error: cURL version 7.10.5 or later is required to compile php with cURL support

yum -y install libcurl libcurl-devel
