nginx安装

1.使用yum安装

yum install nginx

2.配置开机启动

在/etc/init.d/目录下创建 nginx 文件

vi /etc/init.d/nginx

拷贝以下内容

#!/bin/sh # # nginx - this script starts and stops the nginx daemon # # chkconfig: - 85 15 # description: Nginx is an HTTP(S) server, HTTP(S) reverse \ # proxy and IMAP/POP3 proxy server # processname: nginx # config: /etc/nginx/nginx.conf # config: /etc/sysconfig/nginx # pidfile: /var/run/nginx.pid # Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network # Check that networking is up. [ "$NETWORKING" = "no" ] && exit 0 nginx="/usr/sbin/nginx" prog=$(basename $nginx) sysconfig="/etc/sysconfig/$prog" lockfile="/var/lock/subsys/nginx" pidfile="/var/run/${prog}.pid" NGINX_CONF_FILE="/etc/nginx/nginx.conf" [ -f $sysconfig ] && . $sysconfig start() { [ -x $nginx ] || exit 5 [ -f $NGINX_CONF_FILE ] || exit 6 echo -n $"Starting $prog: " daemon $nginx -c $NGINX_CONF_FILE retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval } stop() { echo -n $"Stopping $prog: " killproc -p $pidfile $prog retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval } restart() { configtest_q || return 6 stop start } reload() { configtest_q || return 6 echo -n $"Reloading $prog: " killproc -p $pidfile $prog -HUP echo } configtest() { $nginx -t -c $NGINX_CONF_FILE } configtest_q() { $nginx -t -q -c $NGINX_CONF_FILE } rh_status() { status $prog } rh_status_q() { rh_status >/dev/null 2>&1 } # Upgrade the binary with no downtime. upgrade() { local oldbin_pidfile="${pidfile}.oldbin" configtest_q || return 6 echo -n $"Upgrading $prog: " killproc -p $pidfile $prog -USR2 retval=$? sleep 1 if [[ -f ${oldbin_pidfile} && -f ${pidfile} ]]; then killproc -p $oldbin_pidfile $prog -QUIT success $"$prog online upgrade" echo return 0 else failure $"$prog online upgrade" echo return 1 fi } # Tell nginx to reopen logs reopen_logs() { configtest_q || return 6 echo -n $"Reopening $prog logs: " killproc -p $pidfile $prog -USR1 retval=$? echo return $retval } case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart|configtest|reopen_logs) $1 ;; force-reload|upgrade) rh_status_q || exit 7 upgrade ;; reload) rh_status_q || exit 7 $1 ;; status|status_q) rh_$1 ;; condrestart|try-restart) rh_status_q || exit 7 restart ;; *) echo $"Usage: $0 {start|stop|reload|configtest|status|force-reload|upgrade|restart|reopen_logs}" exit 2 esac

设置/etc/init.d/nginx 执行权限

chmod 777 /etc/init.d/nginx

设置开机默认启动

chkconfig --add nginx //添加系统服务 chkconfig --level 345 nginx on //设置开机启动,启动级别 chkconfig --list nginx //查看开机启动配置信息

nginx控制命令

service nginx start #开启 service nginx stop #停止 service nginx restart #重启 service nginx reload #重新加载

在/etc/nginx/nginx.conf 主配置文件的http块中加入

include /etc/nginx/conf.d/*.conf; #所有的配置全部放入conf.d目录下的以.conf结尾的文件中

3.nginx配置 示例

vim /etc/nginx/conf.d/pysharp.conf

拷贝以下内容

# nginx.conf # the upstream component nginx needs to connect to upstream pysharp { server unix:///project/pysharp/pysharp.sock; # for a file socket # server 127.0.0.1:8001; # for a web port socket (we'll use this first) } # configuration of the server server { # the port your site will be served on listen 80; #listen 443 ssl; # the domain name it will serve for server_name test.cn; # substitute your machine's IP address or FQDN charset utf-8; # max upload size client_max_body_size 75M; # ad just to taste # Django media #location /media { # alias /path/to/your/mysite/media; # your Django project's media files - amend as required #} location /static { alias /project/pysharp/static; # your Django project's static files - amend as required } # Finally, send all non-media requests to the Django server. location / { uwsgi_pass pysharp; include /etc/nginx/uwsgi_params; # the uwsgi_params file you installed } }

uwsgi安装

1.使用源码安装

tar -zxvf uwsgi-2.0.13.1.tar.gz mv uwsgi-2.0.13.1/ uwsgi/ cd uwsgi/ python setup.py build #使用virtualenv make

将安装成功的uwsgi文件复制到/usr/local/bin目录

cp uwsgi /usr/local/bin

2.uwsgi配置 示例

在Django应用程序目录下创建deploy文件夹,加入uwsgi.ini文件

vim /project/pysharp/deploy/uwsgi.ini

拷贝以下内容

[uwsgi] # Django-related settings # the base directory (full path) chdir = /project/pysharp # Django's wsgi file module = pysharp.wsgi # the virtualenv (full path) home = /project/virtualenv/pysharp #使用virtualenv # plugin = python # process-related settings # master master = true # maximum number of worker processes processes = 10 # the socket socket = /project/pysharp/pysharp.sock pidfile = /project/pysharp/pysharp.pid # ... with appropriate permissions - may be needed chmod-socket = 666 # clear environment on exit vacuum = true

启动uwsgi

uwsgi --ini uwsgi.ini

supervisor安装

1.使用python2.7的pip安装

pip install supervisor

2.创建默认的配置文件

echo_supervisord_conf >/etc/supervisord.conf

3.配置开机启动

在/etc/init.d/目录下创建 supervisord 文件

vi /etc/init.d/supervisord

拷贝以下内容

#!/bin/bash # # supervisord This scripts turns supervisord on # chkconfig: 345 83 04 # description: supervisor is a process control utility. It has a web based # xmlrpc interface as well as a few other nifty features. # # source function library . /etc/rc.d/init.d/functions set -a PREFIX=/usr/local/python2.7 SUPERVISORD=$PREFIX/bin/supervisord SUPERVISORCTL=$PREFIX/bin/supervisorctl PIDFILE=/var/supervisor/supervisord.pid LOCKFILE=/var/supervisor/supervisord.lock OPTIONS="-c /etc/supervisord.conf" # unset this variable if you don't care to wait for child processes to shutdown before removing the $LOCKFILE-lock WAIT_FOR_SUBPROCESSES=yes # remove this if you manage number of open files in some other fashion ulimit -n 96000 RETVAL=0 running_pid() { # Check if a given process pid's cmdline matches a given name pid=$1 name=$2 [ -z "$pid" ] && return 1 [ ! -d /proc/$pid ] && return 1 (cat /proc/$pid/cmdline | tr "\000" "\n"|grep -q $name) || return 1 return 0 } running() { # Check if the process is running looking at /proc # (works for all users) # No pidfile, probably no daemon present [ ! -f "$PIDFILE" ] && return 1 # Obtain the pid and check it against the binary name pid=`cat $PIDFILE` running_pid $pid $SUPERVISORD || return 1 return 0 } start() { echo "Starting supervisord: " if [ -e $PIDFILE ]; then echo "ALREADY STARTED" return 1 fi # start supervisord with options from sysconfig (stuff like -c) $SUPERVISORD $OPTIONS # show initial startup status $SUPERVISORCTL $OPTIONS status # only create the subsyslock if we created the PIDFILE [ -e $PIDFILE ] && touch $LOCKFILE } stop() { echo -n "Stopping supervisord: " $SUPERVISORCTL $OPTIONS shutdown if [ -n "$WAIT_FOR_SUBPROCESSES" ]; then echo "Waiting roughly 60 seconds for $PIDFILE to be removed after child processes exit" for sleep in 2 2 2 2 4 4 4 4 8 8 8 8 last; do if [ ! -e $PIDFILE ] ; then echo "Supervisord exited as expected in under $total_sleep seconds" break else if [[ $sleep -eq "last" ]] ; then echo "Supervisord still working on shutting down. We've waited roughly 60 seconds, we'll let it do its thing from here" return 1 else sleep $sleep total_sleep=$(( $total_sleep + $sleep )) fi fi done fi # always remove the subsys. We might have waited a while, but just remove it at this point. rm -f $LOCKFILE } restart() { stop start } case "$1" in start) start RETVAL=$? ;; stop) stop RETVAL=$? ;; restart|force-reload) restart RETVAL=$? ;; reload) $SUPERVISORCTL $OPTIONS reload RETVAL=$? ;; condrestart) [ -f $LOCKFILE ] && restart RETVAL=$? ;; status) $SUPERVISORCTL $OPTIONS status if running ; then RETVAL=0 else RETVAL=1 fi ;; *) echo $"Usage: $0 {start|stop|status|restart|reload|force-reload|condrestart}" exit 1 esac exit $RETVAL

设置/etc/init.d/supervisord 执行权限

chmod 777 /etc/init.d/supervisord

设置开机默认启动

chkconfig --add supervisord //添加系统服务 chkconfig --level 345 supervisord on //设置开机启动,启动级别

在/etc/supervisord.conf 的末尾加上

[include] files = /etc/supervisor/conf.d/*.conf

创建配置文件目录

mkdir /etc/supervisor/conf.d

4.应用程序进程管理配置 示例

vim /etc/supervisor/conf.d/uwsgi_start.conf

拷贝以下内容

; ================================ ; uwsgi supervisor ; ================================ [program:uwsgi_pysharp] command=/usr/local/bin/uwsgi --ini /project/pysharp/deploy/uwsgi.ini directory=/project/pysharp/deploy user=root numprocs=1 stdout_logfile=/var/log/django/uwsgi_start.log #需要先手动创建文件夹 stderr_logfile=/var/log/django/uwsgi_start.log autostart=true autorestart=true startsecs=10 priority=997

supervisor控制命令

supervisorctl status #查看进程运行状态 supervisorctl reload #重新加载配置
