在linux系統下安裝兩個nginx以及啟動、停止、重起

如果沒有安裝過nginx請看：linux下nginx部署以及配置詳解

1、第一個nginx已經安裝完成后，現在安裝第二個nginx

啟動：sudo /usr/sbin/nginx3
重起：sudo /usr/sbin/nginx3 -s reload
停止：sudo /usr/sbin/nginx3 -s stop

一、進入nginx目錄進行編譯安裝

1、切換目錄：

cd /usr/local/src/nginx-1.16.1

安裝第二個路徑會有所不同，我這里安裝的是第三個nginx3，如果要安裝4個 就改為nginx4，需要注意nginx.conf不需要改變，命令如下：

./configure \
--prefix=/usr/local/nginx3 \
--sbin-path=/usr/sbin/nginx3 \
--conf-path=/etc/nginx3/nginx.conf \
--error-log-path=/var/log/nginx3/error.log \
--http-log-path=/var/log/nginx3/access.log \
--pid-path=/var/run/nginx3.pid \
--lock-path=/var/run/nginx3.lock \
--http-client-body-temp-path=/var/tmp/nginx3/client \
--http-proxy-temp-path=/var/tmp/nginx3/proxy \
--http-fastcgi-temp-path=/var/tmp/nginx3/fcgi \
--http-uwsgi-temp-path=/var/tmp/nginx3/uwsgi \
--http-scgi-temp-path=/var/tmp/nginx3/scgi \
--user=nginx3 \
--group=nginx3 \
--with-pcre \
--with-http_v2_module \
--with-http_ssl_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_sub_module \
--with-http_dav_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_stub_status_module \
--with-http_auth_request_module \
--with-mail \
--with-mail_ssl_module \
--with-file-aio \
--with-ipv6 \
--with-http_v2_module \
--with-threads \
--with-stream \
--with-stream_ssl_module

  執行完后下面就是nginx3的路徑

2、安裝編譯：

make && make install

mkdir -pv /var/tmp/nginx3/client

3、添加SysV啟動腳本

vi /etc/init.d/nginx3

按i進入編輯狀態，需要多個nginx修改以下兩個路徑即可，如圖

#!/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. 
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx3"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx3/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
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 $prog -QUIT
    retval=$?
    echo 
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
killall -9 nginx
}
restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: " 
    killproc $nginx -HUP
RETVAL=$?
    echo 
}
force_reload() {
    restart
}
configtest() {
$nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
    status $prog
}
rh_status_q() {
    rh_status >/dev/null 2>&1
}
case "$1" in
    start)
        rh_status_q && exit 0
    $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
      echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" 
        exit 2
esac

 

 

 

4.賦予腳本執行權限

chmod +x /etc/init.d/nginx3

8.添加nginx服務進程用戶

groupadd -r nginx3

useradd -r -g nginx nginx3

9、添加至服務管理列表，設置開機自啟

chkconfig --add nginx3

chkconfig nginx3 on

 10、修改nginx.conf端口號，我這里改為81

vi /etc/nginx3/nginx.conf

 

 11、啟動nginx3

/usr/sbin/nginx3

查看端口號
netstat -lntp

 

 

 

 

 11、在啟動一個nginx

 

 

 12、停止nginx3

sudo /usr/sbin/nginx3 -s stop
