linux服务器centos安装nginx以及相关环境配置 java项目 运维

远程连接服务器ssh连接工具SecureCRT下载：SecureCRT下载链接

1.centos服务器下安装jdk链接

2.centos服务器下安装tomcat链接

3.centos服务器下安装redis链接

4.centos服务器下安装nginx链接

在linux的centos服务器下安装nginx步骤如下：

1.安装相关依赖包

#安装相关依赖包
yum -y install gcc
yum -y install pcre-devel
yum -y install zlib zlib-devel
yum -y install openssl openssl-devel

2.安装nginx以及相关配置

#下载nginx安装包

cd /usr/local/service/nginx

wget http://nginx.org/download/nginx-1.12.2.tar.gz

#解压安装包
tar -zxvf nginx-1.12.2.tar.gz

#配置nginx
./configure

#编译并安装
make
make PREFIX=/usr/local/services/nginx/nginx-1.12.2 install

#查看nginx位置
whereis nginx

#显示安装路径：
nginx: /usr/local/nginx

#配置开机自启动
vi /etc/rc.d/rc.local

#添加以下内容
/usr/local/nginx

# 赋予执行权限
chmod 755 /etc/rc.d/rc.local

3.快速启动脚本生成

#!/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.
[ "$NETWORKING" = "no" ] && exit 0
    nginx="/usr/local/nginx/sbin/nginx"
    prog=$(basename $nginx)
    NGINX_CONF_FILE="/usr/local/nginx/conf/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.新增快速启动脚本

#将上面代码写到 nginx 文件中
vi /usr/bin/nginx

# 添加执行权限
 chmod 755 /usr/bin/nginx

#可以在任意目录下使用 nginx start|stop|status|restart|…
nginx start
nginx stop
nginx status
nginx restart

5.反向代理添加以下内容

在nginx安装目录下的conf下添加此proxy.conf文件，并且在nginx.conf中添加“include proxy.conf”即可

upstream tomcat7server {
    # 访问端口为8070的Tomcat7
    # 这里的192.168.1.166是tomcat 所在主机IP,可以根据实际情况改成你所需要的IP或者域名
    server 192.168.1.166:8070 weight=1;
    }
upstream tomcat8server {
    # 访问端口为8080的Tomcat8
    # 这里的192.168.1.166是tomcat 所在主机IP,可以根据实际情况改成你所需要的IP或者域名
    server 192.168.1.166:8080 weight=1;
    }
server {
        listen      80;
        # 这里的192.168.1.166是nginx 所在主机IP,可以根据实际情况改成你所需要的IP或者域名
        server_name 192.168.1.166;

        location /tomcat7 {
            proxy_pass   http://tomcat7server/;
            index  index.html index.htm;
        }
        location /tomcat8 {
            proxy_pass   http://tomcat8server/;
            index  index.html index.htm;
        }
    }
