Centos6下安装PHP7和Nginx
PHP源码包下载地址:一、安装PHP
# wget http://cn2.php.net/distributions/php-5.6.22.tar.bz2 # wget http://cn2.php.net/distributions/php-7.0.7.tar.bz2更新yum源 这里将Centos的yum源更换为国内的阿里云源。yum安装正常的可以跳过本步骤, 阿里云Linux安装镜像源地址: http://mirrors.aliyun.com/ 1、备份你的原镜像文件,以免出错后可以恢复:
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
# CentOS 5 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo # CentOS 6 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo # CentOS 7 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo3、生成缓存
yum clean all yum makecache安装依赖

tar zxvf /libmcrypt-2.5.8.tar.gz \ && cd /libmcrypt-2.5.8 && ./configure && make && make install && cd - / && rm -rf /libmcrypt* \ && tar zxvf /mhash-0.9.9.9.tar.gz && cd mhash-0.9.9.9 && ./configure && make && make install && cd - / && rm -rf /mhash* \ && tar zxvf /mcrypt-2.6.8.tar.gz && cd mcrypt-2.6.8 && LD_LIBRARY_PATH=/usr/local/lib ./configure && make && make install && cd - / && rm -rf /mcrypt*开始安装 使用./configure --help查看编译支持的选项。如果写了不支持的选项,如php7里不支持--with-mysql=mysqlnd会提示:
configure: WARNING: unrecognized options: --with-mysql
wget http://cn2.php.net/distributions/php-7.0.7.tar.bz2 tar jxvf php-7.0.7.tar.bz2 cd php-7.0.7 $ ./configure --prefix=/usr/local/php --with-config-file-scan-dir=/usr/local/php/etc/ --enable-inline-optimization --enable-opcache --enable-session --enable-fpm --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-pdo-sqlite --with-sqlite3 --with-gettext --enable-mbregex --enable-mbstring --enable-xml --with-iconv --with-mcrypt --with-mhash --with-openssl --enable-bcmath --enable-soap --with-xmlrpc --with-libxml-dir --enable-pcntl --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-sockets --with-curl --with-curlwrappers --with-zlib --enable-zip --with-bz2 --with-gd --enable-gd-native-ttf --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-readline $ make $ make install可选项:
--with-fpm-user=www --with-fpm-group=www这里面开启了很多扩展。如果这时候忘了开启,以后还能加上吗?答案是可以的。以后只需要进入源码的ext目录,例如忘了pdo_mysql,进入ext/pdo_mysql,使用phpize工具,像安装普通扩展一样即可生成pdo_mysql.so。 关于:--enable-safe-mode 开启的话php可以执行一下系统函数,建议关闭(可搜索受此函数影响的php函数)
#如果只需要配置某一个目录可以执行则 设置为on并指定 safe_mode_exec_dir=string目录来执行系统函数。 #本特性已自 PHP 5.3.0 起废弃并将自 PHP 5.4.0 起移除。 safe_mode = offphp7编译不用加这个配置。 编译比较耗内存和CPU。等待半小时左右,编译完成:

$ cp php-7.0.7/php.ini* /usr/local/php/etc/ $ cd /usr/local/php/etc/ $ cp php.ini-production php.ini $ cp php-fpm.conf.default php-fpm.conf $ cp php-fpm.d/www.conf.default php-fpm.d/www.conf $ ls pear.conf php-fpm.conf.default php.ini-development php.ini-production配置php.ini
# 不显示错误,默认
display_errors = Off
# 在关闭display_errors后开启PHP错误日志(路径在php-fpm.conf中配置),默认
log_errors = On
# 字符集,默认
default_charset = "UTF-8"
# 文件上传大小,默认
upload_max_filesize = 2M
# 设置PHP的扩展库路径,,默认被注释了。
extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/"
# 如果不设置extension_dir,也可以直接写绝对位置:
# extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20151012/redis.so
# 设置PHP的时区

# 开启opcache,默认是0
[opcache]
; Determines if Zend OPCache is enabled
opcache.enable=1
配置php-fpm.conf
; 去掉里分号,方便以后重启。建议修改 ; Default Value: none ; 下面的值最终目录是/usr/local/php/var/run/php-fpm.pid ; 开启后可以平滑重启php-fpm pid = run/php-fpm.pid ; 设置错误日志的路径,可以默认值 ; Note: the default prefix is /usr/local/php/var ; Default Value: log/php-fpm.log, 即/usr/local/php/var/log/php-fpm.log error_log = /var/log/php-fpm/error.log ; Log等级,可以默认值 ; Possible Values: alert, error, warning, notice, debug ; Default Value: notice log_level = notice ; 后台运行,默认yes,可以默认值 ; Default Value: yes ;daemonize = yes ; 引入www.conf文件中的配置,可以默认值 include=/usr/local/php/etc/php-fpm.d/*.conf配置www.conf(在php-fpm.d目录下) www.conf这是php-fpm进程服务的扩展配置文件:
; 设置用户和用户组,默认都是nobody。可以默认值 user = nginx group = nginx ; 设置PHP监听 ; 下面是默认值,不建议使用。可以默认值 ; listen = 127.0.0.1:9000 ; 根据nginx.conf中的配置fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock; listen = /var/run/php-fpm/php-fpm.sock ######开启慢日志。可以默认值 slowlog = /var/log/php-fpm/$pool-slow.log request_slowlog_timeout = 10s保存配置文件后,检验配置是否正确的方法为:
/usr/local/php/sbin/php-fpm -t如果出现诸如 test is successful 字样,说明配置没有问题。另外该命令也可以让我们知道php-fpm的配置文件在哪。 建立软连接:
ln -sf /usr/local/php/sbin/php-fpm /usr/bin/ ln -sf /usr/local/php/bin/php /usr/bin/ ln -sf /usr/local/php/bin/phpize /usr/bin/ ln -sf /usr/local/php/bin/php-config /usr/bin/ ln -sf /usr/local/php/bin/php-cig /usr/bin/或者将php编译生成的bin目录添加到当前Linux系统的环境变量中:
echo -e '\nexport PATH=/usr/local/php/bin:/usr/local/php/sbin:$PATH\n' >> /etc/profile && source /etc/profile启动php-fpm
/usr/local/php/sbin/php-fpm如果提示没有www用户(www.conf里填写了www而不是nobody),则新增:
useradd www chown -R www:www /www检测是否启动:
ps aux |grep php-fpm # 另外该命令也可以让我们知道fpm的配置文件在哪。 netstat -ant |grep 9000查看php-fpm进程数:
ps aux | grep -c php-fpmphp-fpm操作汇总:
/usr/local/php/sbin/php-fpm # php-fpm启动 kill -INT `cat /usr/local/php/var/run/php-fpm.pid` # php-fpm关闭 kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid` #php-fpm重启重启方法二:
killall php-fpm /usr/local/php/sbin/php-fpm &如果无法平滑启动,那就终止进程id:
ps aux | grep php-fpm kill -9 1210 #1210指php-fpm进程id
安装包下载地址: http://nginx.org/download/nginx-1.11.1.tar.gz 依赖:二、安装Nginx
# 为了支持rewrite功能,我们需要安装pcre yum install pcre-devel # 需要ssl的支持,如果不需要ssl支持,请跳过这一步 # yum install openssl* # gzip 类库安装,按需安装 # yum install zlib zlib-devel配置编译参数
$ tar -zxvf nginx-1.11.1.tar.gz $ cd nginx-1.11.1 $ ./configure \ --prefix=/usr/local/nginx \ --with-http_stub_status_module \ --with-http_ssl_module \ --with-http_realip_module \ --with-http_sub_module \ --with-http_gzip_static_module \ --with-pcre配置ok:

make make install设置软连接:
ln -sf /usr/local/nginx/sbin/nginx /usr/sbin检测nginx:
nginx -t显示:nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful 成功了。我们重新配置下nginx.conf:
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
# 解决虚拟主机名字过长 http://www.jb51.net/article/26412.htm
server_names_hash_bucket_size 128;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
autoindex on;# 显示目录
autoindex_exact_size on;# 显示文件大小
autoindex_localtime on;# 显示文件时间
include vhosts/*.conf;
}
配置localhost:
vim ./vhosts/localhost.conf
server { listen 80; server_name localhost; #charset utf-8; #access_log logs/host.access.log main; location / { root /www/www/; index index.php index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { root /www/www/; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } }启动nginx:
/usr/local/nginx/sbin/nginx # 或者 nginx重启:
/usr/local/nginx/sbin/nginx -s reload # 或者 nginx -s reload停止:
/usr/local/nginx/sbin/nginx -s stop # 或者 nginx -s stop如果提示80端口被占用了,可以使用ps aunx | grep 80查看。一般是apache占用了。可以使用:
chkconfig --list chkconfig nginx on service apache off禁止apache启动并关闭apache服务。
1、安装swoole Swoole: PHP的异步、并行、高性能网络通信引擎:http://www.swoole.com/三、安装扩展
wget https://github.com/swoole/swoole-src/archive/swoole-1.8.5-stable.zip unzip swoole-1.8.5-stable.zip cd swoole-1.8.5-stable phpize ./configure make && make install2、安装redis
wget https://github.com/nicolasff/phpredis/archive/2.2.4.tar.gz tar -zxvf 2.2.4 cd phpredis-2.2.4/ phpize ./configure make && make install
不重载配置启动新/旧工作进程四、信号管理
kill -HUP 旧/新版主进程号从容关闭旧/新进程
kill -QUIT 旧/新主进程号如果此时报错,提示还有进程没有结束就用下面命令先关闭旧/新工作进程,再关闭主进程号:
kill -TERM 旧/新工作进程号升级、添加或删除模块时,我们需要停掉服务器
kill -USR2 旧版程序的主进程号或进程文件名
