nano 新增用户和用户组

groupadd www
useradd -g www www

下载PHP源码

cd /usr/local/src
wget "https://downloads.php.net/~cmb/php-7.3.0.tar.gz"
tar xzvf php-7.3.0.tar.gz
cd  php-7.3.0

编译

./configure --prefix=/usr/local/php --with-fpm-user=www --with-fpm-group=www --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-jpeg-dir --with-xmlrpc --with-xsl --with-zlib --with-bz2 --with-mhash --enable-fpm --enable-bcmath --enable-libxml --enable-inline-optimization --enable-mbregex --enable-mbstring --enable-opcache --enable-pcntl --enable-shmop --enable-soap --enable-sockets --enable-sysvsem --enable-sysvshm --enable-xml --enable-zip --enable-fpm

`注:--with-fpm-user=www --with-fpm-group=www
这里使用www www 用户、用户组
编译出来的程序启动,就是归属这个用户、用户组`

编译出错

configure: error: libxml2 not found. Please check your libxml2 installation.

安装相关组件

yum install -y libxml2-devel bzip2-devel curl-devel libjpeg-devel libpng-devel freetype-devel libxslt-devel libzip-devel openssl-devel

libzip版本过低

checking for libzip... configure: error: system libzip must be upgraded to version >= 0.11

删除重新安装

#先删除旧版本
yum remove -y libzip

#下载编译安装
wget https://nih.at/libzip/libzip-1.2.0.tar.gz
tar -zxvf libzip-1.2.0.tar.gz
cd libzip-1.2.0
./configure
make && make install

off_t undefined 报错

configure: error: off_t undefined; check your library configuration

off_t 类型是在 头文件 unistd.h中定义的,
在32位系统 编程成 long int ,64位系统则编译成 long long int ,
在进行编译的时候 是默认查找64位的动态链接库,
但是默认情况下 centos 的动态链接库配置文件/etc/ld.so.conf里并没有加入搜索路径,
这个时候需要将 /usr/local/lib64 /usr/lib64 这些针对64位的库文件路径加进去。

#添加搜索路径到配置文件
echo '/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64'>>/etc/ld.so.conf

#然后 更新配置
ldconfig -v

安装

make && make install
报错
usr/local/include/zip.h:59:21: fatal error: zipconf.h: No such file or directory
解决方法
cp /usr/local/lib/libzip/include/zipconf.h /usr/local/include/zipconf.h

配置,建立目录

cp php.ini-production /usr/local/php/lib/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
ln -s /usr/local/php/sbin/php-fpm /usr/local/bin

cd /usr/local/php/etc/php-fpm.d
vim www.conf
输入
[www]
listen = 127.0.0.1:9080   
listen.mode = 0666      
user = www  #php代码目录权限 需要跟这个一致,
group = www #php代码目录权限 需要跟这个一致

pm = dynamic
pm.max_children = 128
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 10000

rlimit_files = 1024

加入 systemtl 服务

cd /usr/local/src/php-7.3.0/sapi/fpm
cp php-fpm.service /usr/lib/systemd/system/
