How to install PHP7 under centos7?

The added library file path must be consistent with the system platform arch. For 32bit systems, just add [/usr/local/lib] directly. For 64bit systems, add [/usr/local/lib64.] Otherwise The error will still be reported. This article will introduce in detail how to install PHP7 under centos7.

1. Official website installation method:

2. Compile and install

1. Download php7

wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.20.tar.gz/from/this/mirror

or download directly from the webpage

http://php.net/get/php-7.1.20.tar.gz/from/a/mirror

2. Unzip php7

tar -xvf php7.tar.gz

3. Enter the php directory

cd /usr/local/src/php-7.1.20

4. Install dependency packages

yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel

5. Compile configuration (If an error occurs, it is basically caused by the dependency files in the previous step not being installed)

./configure \
--prefix=/software/php \
--with-config-file-path=/etc \
--enable-fpm \
--with-fpm-user=www \
--with-fpm-group=www \

Error reporting

The most practical solution is as follows:

Problem:

1:  wget ftp://mcrypt.hellug.gr/pub/crypto/mcrypt/libmcrypt/libmcrypt-2.5.7.tar.gz

2:  tar zxf libmcrypt-2.5.7.tar.gz

3:  ./configure --prefix=/usr/local

4:  make && make install

Problem: configure: error: Don't know how to define struct flock on this system, set --enable-opcache=no

Solution: Solution:

vim /etc/ld.so.conf.d/local.conf

# Edit the library file

/usr/local/lib

# Add this line

ldconfig -v

# Make it take effect

Note:

The library file path added here must be consistent with your system platform arch, 32bit system directly Just add /usr/local/lib. For 64bit systems, you need to add /usr/local/lib64. Otherwise, an error will still be reported. I just added /usr/ local/lib could not be edited alive and well, but it was later changed to /usr/local/lib64.

6. Formal installation

make && make install

7. Configuration Environment variables

vi /etc/profile
PATH=$PATH:/usr/local/php/bin
export PATH
source /etc/profile

8. Configure php-fpm

cp php.ini-production /usr/local/php/etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm /usr/local/php/etc/php-fpm
chmod +x /usr/local/php/etc/php-fpm
ln /usr/local/php/etc/php.ini /etc/php.ini

9. Create www user

useradd www

10. Configure startup parameters

vim /usr/local/php/etc/php-fpm.d/www.conf
pm.max_children = 500
pm.start_servers = 105
pm.min_spare_servers = 10
pm.max_spare_servers = 200

11.Start php-fpm

/usr/local/php/etc/php-fpm start
设置 php-fpm开机启动
cp /usr/local/src/php-5.5.14/sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm #拷贝php-fpm到启动目录
chmod +x /etc/rc.d/init.d/php-fpm #添加执行权限
chkconfig php-fpm on #设置开机启动
service php-fpm start
pkill php-fpm 强制关闭
