tony_nginx的安装和配置
yum安装nginx
Centos默认的yum源里没有nginx，需要手动添加源，有两种方法：
使用nginx提供的一个源设置安装包
nginx下载页面：http://nginx.org/en/download.html
nginx提供4个版本的系统的源：
我选择Centos6，文件名为：nginx-release-centos-6-0.el6.ngx.noarch.rpm。
在服务器上安装：
rpm -ivh nginx-release-centos-6-0.el6.ngx.noarch.rpm
之后便可以使用yum快速安装了：
yum install nginx
手动添加nginx源
cd /etc/yum.repos.d
vim nginx.repo
#内容为：
[nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/6/$basearch/ gpgcheck=0 enabled=1
baseurl中centos和6可以更改为自己的版本，比如redhat 5版本的链接为：
baseurl=http://nginx.org/packages/rhel/5/$basearch/
详情可以自己看nginx的下载页面，包括其他系统的源安装方法。
相关路径
nginx可执行文件：/usr/sbin/nginx
nginx配置目录：/etc/nginx
nginx log目录：/var/log/nginx
编译安装nginx
我的nginx编译安装代码：
yum install perl-ExtUtils-Embed.x86_64 pcre-devel.x86_64
#根据自己的需求，选择参数，可用的参数可以使用./configure --help命令查看
./configure --prefix=/opt/nginx
--with-http_gzip_static_module
--with-http_perl_module
--with-pcre
--with- rtsig_module
--with-select_module
--with-poll_module
--with-file-aio
make
make install
为编译安装的nginx配置init脚本：
vim /etc/init.d/nginx
#内容取自yum安装的nginx后，生成的文件，改下里面的路径即可使用了
#!/bin/sh # # nginx Startup script for nginx # # chkconfig: - 85 15 # processname: nginx # config: /opt/nginx/conf/nginx.conf # config: /etc/sysconfig/nginx # pidfile: /opt/nginx/logs/nginx.pid # description: nginx is a HTTP and reverse proxy server # ### BEGIN INIT INFO # Provides: nginx # Required-Start: $local_fs $remote_fs $network # Required-Stop: $local_fs $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: start and stop nginx ### END INIT INFO # Source function library. . /etc/rc.d/init.d/functions if [ -f /etc/sysconfig/nginx ]; then . /etc/sysconfig/nginx fi prog=nginx nginx=${NGINX-/opt/nginx/sbin/nginx} conffile=${CONFFILE-/opt/nginx/conf/nginx.conf} lockfile=${LOCKFILE-/var/lock/subsys/nginx} pidfile=${PIDFILE-/opt/nginx/logs/nginx.pid} SLEEPMSEC=100000 RETVAL=0 start() { echo -n $"Starting $prog: " daemon --pidfile=${pidfile} ${nginx} -c ${conffile} RETVAL=$? echo [ $RETVAL = 0 ] && touch ${lockfile} return $RETVAL } stop() { echo -n $"Stopping $prog: " killproc -p ${pidfile} ${prog} RETVAL=$? echo [ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile} } reload() { echo -n $"Reloading $prog: " killproc -p ${pidfile} ${prog} -HUP RETVAL=$? echo } upgrade() { oldbinpidfile=${pidfile}.oldbin configtest -q || return 6 echo -n $"Staring new master $prog: " killproc -p ${pidfile} ${prog} -USR2 RETVAL=$? echo /bin/usleep $SLEEPMSEC if [ -f ${oldbinpidfile} -a -f ${pidfile} ]; then echo -n $"Graceful shutdown of old $prog: " killproc -p ${oldbinpidfile} ${prog} -QUIT RETVAL=$? echo else echo $"Upgrade failed!" return 1 fi } configtest() { if [ "$#" -ne 0 ] ; then case "$1" in -q) FLAG=$1 ;; *) ;; esac shift fi ${nginx} -t -c ${conffile} $FLAG RETVAL=$? return $RETVAL } rh_status() { status -p ${pidfile} ${nginx} } # See how we were called. case "$1" in start) rh_status >/dev/null 2>&1 && exit 0 start ;; stop) stop ;; status) rh_status RETVAL=$? ;; restart) configtest -q || exit $RETVAL stop start ;; upgrade) upgrade ;; condrestart|try-restart) if rh_status >/dev/null 2>&1; then stop start fi ;; force-reload|reload) reload ;; configtest) configtest ;; *) echo $"Usage: $prog {start|stop|restart|condrestart|try-restart|force-reload|upgrade|reload|status|help|configtest}" RETVAL=2 esac exit $RETVAL
使用chkconfig安装为安装启动项
chkconfig --add nginx chkconfig nginx on
nginx命令:
启动：nginx
停止：nginx -s stop
重置生效：nginx -s reload
