近期要上线几个基于tornado+motor的移动端接口服务,众所周知,Apache和tornado天生八字不合,尤其apache对python3尤为的不友好,tornado和nginx才是木石前盟,另外由于apache目前系统占用确实比较高,不光进程数多,httpd竟然占用了200多M,太庞大,决定换为较轻量级,高并发的nginx。
如上图所示:系统也就2g ,除了mysql占用的100M, httpd 占了1/2 还多
首先由于apache和nginx默认都是监听80端口,所以首先要停止apache服务(为了保险起见,只是停止服务,不要卸载)
systemctl stop httpd
第二步,安装nginx
#设置源
sudo rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
#安装
yum install -y nginx
#启动服务
systemctl start nginx.service
#开机自启
systemctl enable nginx.service
由于机器上还有一些php服务,而nginx需要php-fpm的支持才能代理php,所以安装php-fpm
yum install php-fpm
yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt
开启php服务
systemctl start php-fpm
开机启动php服务
systemctl enable php-fpm
然后将原来apache的服务配置翻译成nginx的,二者大同小异,值得一提的是,关于https服务,nginx配置要简单很多
apache配置:
<VirtualHost _default_:443>
# General setup for the virtual host
DocumentRoot "/opt/v3u"
ServerName v3u.cn:443
ServerAdmin you@example.com
ErrorLog "/opt/lampp/logs/error_log"
TransferLog "/opt/lampp/logs/access_log"
# SSL Engine Switch:
# Enable/Disable SSL for this virtual host.
SSLEngine on
SSLCertificateFile "证书目录"
SSLCertificateKeyFile "证书目录"
SSLCertificateChainFile "证书目录"
<FilesMatch ".(cgi|shtml|phtml|php)$">
SSLOptions +StdEnvVars
</FilesMatch>
<Directory "/opt/lampp/cgi-bin">
SSLOptions +StdEnvVars
</Directory>
BrowserMatch "MSIE [2-5]"
nokeepalive ssl-unclean-shutdown
downgrade-1.0 force-response-1.0
CustomLog "/opt/lampp/logs/ssl_request_log"
"%t %h %{SSL_PROTOCOL}x %{SSL_CIPHER}x "%r" %b"
</VirtualHost>
翻译为ngixn的配置:
server {
listen 443 ssl;
server_name v3u.cn;
root /opt/v3u;
location / {
index index.html index.htm index.php;
rewrite ^/sitemap.xml$ /Index_sitemap last;
rewrite ^/resume$ /Index_resume last;
rewrite ^/search_(.+?)$ /Index_search_text_$1 last;
rewrite ^/a_id_(.+?)$ /Index_a_id_$1 last;
rewrite ^/ls_id_(.+?)$ /Index_ls_id_$1 last;
rewrite ^/l_id_(.+?)$ /Index_l_id_$1 last;
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?s=$1 last;
break;
}
}
ssl_certificate 证书目录;
ssl_certificate_key 证书目录;
location ~ .php(.*)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $1;
include fastcgi_params;
}
}
修改好配置文件,重启nginx
systemctl restart nginx.service
最后别忘了将apache的开机自启关闭
systemctl disable httpd
ok,到此从apache迁移到nginx就配置结束了,总体上没啥难度
由图上可知,应用了nginx之后,系统感觉清爽了很多,内存也节约了大约300多m,系统告别臃肿,轻装上阵。
