Centos7 yum源没有PHP7的安装包，贼不方便。。。
Step 1 :换源
yum install epel-release
rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
不安装epel有可能会报错。
Step 2: 安装PHP7.2
yum install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
Step 3: 安装pecl
yum install php72w-devel
yum install php72w-pear
不能偷懒,少写72w,用php-pear
这里可能会报错：
错误：php72w-common conflicts with php-common-5.4.16-45.el7.x86_64
Step 4:安装 swoole
pecl install swoole
错误处理
- C++ preprocessor “/lib/cpp” fails sanity check
没有c++库
yum install glibc-headers
yum install gcc-c++
- fatal error: openssl/ssl.h: No such file or directory
yum install openssl-devel
- #error “Enable http2 support, require nghttp2 library.”
wget https://github.com/nghttp2/nghttp2/releases/download/v1.34.0/nghttp2-1.34.0.tar.bz2
tar -xjf nghttp2-1.34.0.tar.bz2
如果解压报错
bzip2：无法 exec: 没有那个文件或目录
执行
yum install -y bzip2
接着
cd nghttp2-1.34.0
./configure
make
make install
- fatal error: hiredis/hiredis.h: No such file or directory
wget https://github.com/redis/hiredis/archive/v0.14.0.tar.gz
tar xzvf v0.14.0.tar.gz
cd hiredis-0.14.0/
make && make install
执行
vi ~/.bash_profile
[最后加上这句]export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
[退出来]
source ~/.bash_profile
不修改.bash_profile文件，扩展添加会报错
Step 5:修改配置
php.ini 中加入
extension=swoole.so
执行
php -m
如果有swoole 扩展就大功告成。
附加：
我在supervisor 中运行swoole程序，报错
PHP Startup: Unable to load dynamic library ‘swoole.so’ (tried: /usr/lib64/php/modules/swoole.so (libhiredis.so.0.14: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/swoole.so.so (/usr/lib64/php/modules/swoole.so.so: cannot open shared object file: No such file or directory))
困扰了我很久，然后找到解决办法
echo '/usr/local/lib' >>/etc/ld.so.conf
ldconfig
