CentOS 6 无法安装 Swoole 提示 GCC 4.8 or later required

自行编译安装 gcc,依然提示,

当使用 gcc -v 提示已安装 gcc version 4.8.2

但使用 yum install gcc 提示是 4.4 且为最新版本

解决办法,卸载 yum 版 gcc,然后重新编译安装

yum remove gcc

CentOS 6 升级安装gcc 4.8

https://blog.csdn.net/bdss58/article/details/78175892

1. 导入CERN’s GPG key

rpm --import http://linuxsoft.cern.ch/cern/slc68/x86_64/RPM-GPG-KEY-cern

2. 添加slc6-devtoolset yum源

wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo

3. 安装devtoolset-2

yum install devtoolset-2

4. 生效devtoolset-2

source /opt/rh/devtoolset-2/enable

可以将此命令写入.bashrc中,以免每次手动执行

echo 'source /opt/rh/devtoolset-2/enable' >> ~/.bashrc

验证一下gcc版本:

$ gcc --version
gcc (GCC) 4.8.2 20140120 (Red Hat 4.8.2-15)

Swoole 编译报错 fatal error: hiredis/hiredis.h: No such file or directory

Swoole 当使用参数 –enable-async-redis 时编译报错

/tmp/pear/temp/swoole/swoole_redis.c:20:29: fatal error: hiredis/hiredis.h: No such file or directory

启用 Swoole 的 async-redis 扩展需要安装 hiredis,hiredis 需要 redis

安装 Redis

cd ~
wget http://download.redis.io/releases/redis-5.0.0.tar.gz
tar xzf redis-5.0.0.tar.gz
cd redis-5.0.0
make

安装 hiredis

cd ~
wget https://github.com/redis/hiredis/archive/v0.13.3.zip
unzip v0.13.3.zip
cd hiredis-0.13.3
make -j
sudo make install
sudo ldconfig

Swoole 编译错误 Enable http2 support, require nghttp2 library

安装 nghttp2

In file included from /tmp/pear/temp/swoole/swoole.c:16:0:
/tmp/pear/temp/swoole/php_swoole.h:142:2: error: #error "Enable http2 support, require nghttp2 library."
 #error "Enable http2 support, require nghttp2 library."

swoole 的 http2 模块依赖  nghttp2库,安装即可

wget https://github.com/nghttp2/nghttp2/releases/download/v1.30.0/nghttp2-1.30.0.tar.bz2 
tar -jxvf nghttp2-1.30.0.tar.bz2 
cd nghttp2-1.30.0 
./configure
make
make install

安装 PostgreSQL

如未安装报错如下:

configure: error: Cannot find libpq-fe.h. Please confirm the libpq or specify correct PostgreSQL(libpq) installation path
ERROR: `/tmp/pear/temp/swoole/configure --with-php-config=/usr/local/php/bin/php-config --enable-sockets=yes --enable-openssl=yes --enable-http2=yes --enable-mysqlnd=yes --enable-coroutine-postgresql=yes --enable-debug-log=yes' failed

解决办法

yum -y install postgresql-devel

Swoole 绑定域名 80 端口 (Nginx 监听转发)

启动 Swoole 的 http server,可以使用 IP + 端口 进行访问

创建 Nginx 虚拟域名

vim swotp.liuguofeng.com.conf
server
    {
        listen 80;
        server_name swotp.liuguofeng.com ;
        index index.html index.htm index.php default.html default.htm default.php;
        root  /home/wwwroot/swoole_thinkphp.liuguofeng.com;

        location / {
                if (!-e $request_filename) {
                proxy_pass http://127.0.0.1:8811;
                }
        }
    }

重启 Nginx,DNS 指向 IP
