看到一个基于swoole的聊天室,php 环境根据yum安装lnmp安装好了，之后安装swoole,但是失败了

[root@VM_0_14_centos html]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[root@VM_0_14_centos html]# pecl install swoole
Could not download from "http://pecl.php.net/get/swoole-4.2.7.tgz", cannot download "pecl/swoole" (File http://pecl.php.net:80/get/swoole-4.2.7.tgz not valid (received: HTTP/1.0 500 Internal Server Error
))
Error: cannot download "pecl/swoole"
Download failed
install failed

于是开始源码安装

#git clone https://github.com/swoole/swoole-src
#cd swoole-src
#phpize 
#./configure
checking for gcc... no
checking for cc... no
checking for cl.exe... no
configure.sh:error:no acceptable C compiler found in $PATH
See 'config.log' for more details.

更新：

后来重新安装成功了

#yum -y install gcc
#./configure
checking how to run the C++ preprocessor... /lib/cpp
configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
#yum install glibc-headers gcc-c++
#./configure

Build complete.
Don't forget to run 'make test'.

Installing shared extensions:     /usr/lib64/php/modules/
Installing header files:          /usr/include/php/
#vi /etc/php.ini
extension= /usr/lib64/php/modules/swoole.so

但是使用的时候Redis启动不了。

[root@VM_0_14_centos php-chatroom]# systemctl start redis
Job for redis.service failed because the control process exited with error code. See "systemctl status redis.service" and "journalctl -xe" for details.

更新：
在systemctl 启动redis
找到答案 chown redis:redis /var/log/redis/redis.log

[root@VM_0_14_centos php-chatroom]# systemctl status redis
