编译&&安装

    make && make install

查看php-fpm配置文件，一般在：/usr/local/php/etc目录下，也可通过命令查找：find / -name php-fpm.conf

开机自启动文件/etc/init.d/php-fpm

    #!/bin/sh  
    # chkconfig:   2345 15 95

    phpfpm="/usr/local/php/sbin/php-fpm"  
    prog=$(basename ${phpfpm})  
    
    lockfile=/var/lock/subsys/phpfpm
    
    start() {  
        [ -x ${phpfpm} ] || exit 5  
        echo -n $"Starting $prog: "  
        daemon ${phpfpm}
        retval=$?  
        echo  
        [ $retval -eq 0 ] && touch $lockfile  
        return $retval  
    }  
    
    stop() {  
        echo -n $"Stopping $prog: "  
        killproc $prog -QUIT  
        retval=$?  
        echo  
        [ $retval -eq 0 ] && rm -f $lockfile  
        return $retval  
    }  
    
    restart() {  
        configtest || return $?  
        stop  
        start  
    }  
    
    reload() {  
        configtest || return $?  
        echo -n $"Reloading $prog: "  
        killproc ${phpfpm} -HUP  
        RETVAL=$?  
        echo

    force_reload() {  
        restart  
    }  
    
    configtest() {  
      ${phpfpm} -t
    }  
    
    rh_status() {  
        status $prog  
    }  
    
    rh_status_q() {  
        rh_status >/dev/null 2>&1  
    }  
    
    case "$1" in  
        start)  
            rh_status_q && exit 0  
            $1  
            ;;  
        stop)  
            rh_status_q || exit 0  
            $1  
            ;;  
        restart|configtest)  
            $1  
            ;;  
        reload)  
            rh_status_q || exit 7  
            $1  
            ;;  
        status)  
            rh_status  
            ;;  
        *)  
            echo $"Usage: $0 {start|stop|status|restart|reload|configtest}"  
            exit 2  
     esac    

赋予脚本可执行权限

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

将php-fpm服务加入chkconfig管理列表

    chkconfig --add /etc/init.d/php-fpm
    chkconfig php-fpm on
    # 启动
    systemctl start php-fpm

运行php-fpm

    sudo php-fpm -R 或者 systemctl start php-fpm.service

让Nginx支持php在nginx.conf中添加

    location / {
            index index.php index.html index.htm;
            try_files $uri $uri/ =404;
         }
         
        location ~ \.php$ {
            fastcgi_pass 127.0.0.1:9001;  
            fastcgi_index index.php;  
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;  
            include fastcgi_params;  
        }

8. Centos 7 安装PHP 7 --skip-broken 问题解决：即运行yum clean all即可
9. 参考文章CentOS 7 安装 PHP 7
10. undefined reference to libiconv问题即则编辑Makefile文件找到
    EXTRA_LIBS = -lcrypt -lz -lcrypt -lrt -lmcrypt -lltdl -lpng -lz -ljpeg -lcurl -lz -lrt -lm -ldl -lnsl -lrt -lxml2 -lz -lm -lssl -lcrypto -lcurl -lxml2 -lz -lm -lssl -lcrypto -lfreetype -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lssl -lcrypto -lcrypt
    在最后添加 -liconv
11. 安装目录在/usr/local/php/
12. 将源码目录下的php.ini-development拷贝到/etc目录下：cp php.ini-development /etc/php.ini
