#编译安装

3、./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-ctype --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --enable-mysqlnd-compression-support --with-freetype-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --with-gd --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-ldap-sasl --with-xmlrpc --enable-zip --enable-soap --with-gettext --enable-fpm --with-jpeg-dir --with-png-dir

echo $?
make && make install


        #错误解决
        错误1：checking for libzip... configure: error: system libzip must be upgraded to version >= 0.11
        解：----------
    yum remove -y libzip #先删除旧版本
    #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

        错误2：configure: error: off_t undefined; check your library configuration
        解决：----------

vim /etc/ld.so.conf
#添加如下几行
/usr/local/lib64
/usr/local/lib
/usr/lib
/usr/lib64
#保存退出
:wq
ldconfig -v # 使之生效


        错误3：/usr/local/include/zip.h:59:21: 致命错误:zipconf.h    make: *** [ext/zip/php_zip.lo] 错误 1
        解决：-------

#配置环境变量和systemctl
4、vim /etc/profile
export PATH=$PATH:/usr/local/php/sbin:/usr/local/php/bin

vim /usr/lib/systemd/system/php-fpm.service
[Unit]
Description=php-fpm
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/php/sbin:/sur/local/php/bin
[install]
WantedBy=multi-user.target

systemctl daemon-reload 加载一下，告诉systemd系统。


#启动

5、sytemctl start php-fpm


#调试PHP与nginx环境，修改配置nginx.conf

6、vim nginx.conf
增加一个index.php
index index.html index.htm index.php;
取消注释：
location ~ .php$ {
root /data/nginx/web;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
#并把/scripts替换$document_root这个

#测试：
vim 1.php
phpinfo();
?>
