Centos7下安装Nginx

1.环境安装

yum install -y gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

---

2.编译安装

需要创建/var/temp/nginx及/usr/local/nginx两个目录，程序会被安装在/opt/nginx目录下

mkdir -p /var/temp/nginx

mkdir -p /usr/local/nginx

• tar -zxvf nginx-1.11.6.tar.gz

• cd nginx-1.11.6

./configure 
--prefix=/opt/nginx 
--pid-path=/usr/local/nginx/nginx.pid 
--lock-path=/var/lock/nginx.lock 
--error-log-path=/var/log/nginx/error.log 
--http-log-path=/var/log/nginx/access.log 
--with-http_gzip_static_module 
--http-client-body-temp-path=/var/temp/nginx/client 
--http-proxy-temp-path=/var/temp/nginx/proxy 
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi 
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi 
--http-scgi-temp-path=/var/temp/nginx/scgi 
--with-stream

• make
• make install

---

3.配置成服务并且设置为开机自启动

• vim /etc/init.d/nginx
  #注意：修改PATH和NAME字段, 匹配自己的安装路径

#! /bin/bash
# chkconfig: - 85 15
PATH=/opt/nginx
DESC="nginx daemon"
NAME=nginx
DAEMON=$PATH/sbin/$NAME
CONFIGFILE=$PATH/conf/$NAME.conf
PIDFILE=/usr/local/nginx/nginx.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
do_stop() {
$DAEMON -s stop || echo -n "nginx not running"
}
do_reload() {
$DAEMON -s reload || echo -n "nginx can"t reload"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
reload|graceful)
echo -n "Reloading $DESC configuration..."
do_reload
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0

• 设置执行权限
  chmod a+x /etc/init.d/nginx
• 注册成服务
  chkconfig --add nginx
• 设置开机启动
  chkconfig nginx on
• 启动/停止/重启

systemctl start nginx.service       #启动nginx服务
systemctl stop nginx.service        #停止nginx服务  
systemctl restart nginx.service     #重启nginx服务
systemctl reload nginx.service      #重新读取nginx配置(不用停止nginx服务就能使修改的配置生效)

4.配置参考

worker_processes  4;

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;
