7. 安装go环境
7.1 下载安装源包
# cd /usr/local/src
# wget http://golangtc.com/static/go/1.8/go1.8.linux-amd64.tar.gz

7.2 解压安装
# cd /usr/local/src
# tar zxvf go1.8.linux-amd64.tar.gz
# cp -a go /usr/local/
# mkdir /data/                #创建go项目工作目录
# setfacl -R -m o::r-- /data
# setfacl -R -m g::rw- /data
# setfacl -R -m u:shangtv:rwx /data
# setfacl -R -d --set o::r-- /data
# setfacl -R -d --set g::rw- /data
# setfacl -R -d --set u:shangtv:rwx /data
# mkdir /data/mygo
7.3 设置go环境变量
# echo "export GOROOT=/usr/local/go" >> /etc/profile
# echo "export GOBIN=$GOROOT/bin" >> /etc/profile
# echo "export GOPKG=$GOROOT/pkg/tool/linux_amd64" >> /etc/profile
# echo "export GOARCH=amd64" >> /etc/profile
# echo "export GOOS=linux" >> /etc/profile
# echo "export GOPATH=/data/mygo/" >> /etc/profile
# echo "export PATH=.:$PATH:$GOBIN:$GOPKG" >> /etc/profile

7.4 检查go版本
# go version
 go version go1.8 linux/amd64

7.5 设置nginx反向代理
upstream goweb {
        #server 120.76.40.33:8082 backup;
        server 120.76.96.73:3000;
}
server
{
    listen 8082;
    server_name shangtv.cn;
    error_log /usr/local/nginx/logs/fsabc_error.log debug;
    access_log /usr/local/nginx/logs/fsabc_access.log;
location / {
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Nginx-Proxy true;
        proxy_pass http://goweb;
        add_header Access-Control-Allow-Origin *;
        add_header Access-Control-Allow-Credentials true;
        add_header Access-Control-Allow-Headers Content-Type,Accept;
        add_header Access-Control-Allow-Methods GET;
    }
}

8. 安装redis数据库
8.1 安装redis组件
    # yum install tcl
    
8.2 下载redis源码包
    # cd /usr/local/src
    # wget http://download.redis.io/releases/redis-3.0.7.tar.gz
    # tar -zvxf redis-3.0.7.tar.gz
    # cd redis-3.0.7
    # make
    # make install         #按提示install
    # cd src/
    # make install
下面提示就说明成功
Hint: To run 'make test' is a good idea ;) 
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
    INSTALL install
以上redis已完成编译安装
在/usr/local/bin生成redis-benchmark、redis-check-aof、redis-check-dump、redis-cli、redis-sentinel 、redis-server六个文件，其中redis-server为启动服务

8.3 配置redis文件
    # cp /usr/local/src/redis-3.0.7/redis.conf /etc/
    # chmod 755 /etc/redis.conf

8.4 启动redis
    # /usr/local/bin/redis-server /etc/redis.conf

8.5 修改redis.conf配置文件 vim /etc/redis.conf
    下面是redis.conf的主要配置参数的意义：
    daemonize：是否以后台daemon方式运行
    pidfile：pid文件位置
    port：监听的端口号
    timeout：请求超时时间
    loglevel：log信息级别
    logfile：log文件位置
    databases：开启数据库的数量
    save * *：保存快照的频率，第一个*表示多长时间，第三个*表示执行多少次写操作。    在一定时间内执行一定数量的写操作时，自动保存快照。可设置多个条件。
    rdbcompression：是否使用压缩
    dbfilename：数据快照文件名（只是文件名，不包括目录）
    dir：数据快照的保存目录（这个是目录）
    appendonly：是否开启appendonlylog，开启的话每次写操作会记一条log，这会提高数    据抗风险能力，但影响效率。
    appendfsync：appendonlylog如何同步到磁盘（三个选项，分别是每次写都强制调用fsync、每秒启用一次fsync、不调用fsync等待系统自己同步）
8.6 修改 daemonize yes,以后台运行
    这时你可以打开一个终端进行测试了，配置文件中默认的监听端口是6379

8.7 建立用户和日志目录
第一次启动时建议为Redis建立用户和日志目录
# groupadd redis
# useradd -g redis redis -s /bin/false
# mkdir -p /var/lib/redis #db文件放在这里，需要修改redis.conf
# mkdir -p /var/log/redis #日志放在这里
# chown redis.redis /var/lib/redis 
# chown redis.redis /var/log/redis
    
# vim /etc/redis.conf
# The working directory.
#
    # The DB will be written inside this directory, with the filename specified
    # above using the 'dbfilename' configuration directive.
    #
    # Also the Append Only File will be created inside this directory.
    #
    # Note that you must specify a directory here, not a file name.
    dir /var/lib/redis
---------------------------------------------------------------------------------------
找到日志logfile
    # Specify the log file name. Also 'stdout' can be used to force
    # Redis to log on the standard output. Note that if you use standard
    # output for logging but daemonize, logs will be sent to /dev/null
    logfile /var/log/redis/redislog
    
或者编写启动脚本，加入到服务
配置Init脚本
Redis管理脚本基于Ubuntu 的发行版上的，在Centos linux 上并不能用，下面有个脚本可以用于CentOS 。 
用这个脚本管理之前，需要先配置下面的内核参数，否则Redis脚本在重启或停止redis时，将会报错，并且不能自动在停止服务前同步数据到磁盘上： 
# vim /etc/sysctl.conf
vm.overcommit_memory = 1
然后应用生效： 
# sysctl -p
建立redis启动脚本： 
# vim /etc/init.d/redis

#!/bin/bash 
# 
# Init file for redis 
# 
# chkconfig: - 80 12 
# description: redis daemon 
# 
# processname: redis 
# config: /etc/redis.conf 
# pidfile: /var/run/redis.pid 
source /etc/init.d/functions 
#BIN="/usr/local/bin" 
BIN="/usr/local/bin" 
CONFIG="/etc/redis.conf" 
PIDFILE="/var/run/redis.pid" 
### Read configuration 
[ -r "$SYSCONFIG" ] && source "$SYSCONFIG" 
RETVAL=0 
prog="redis-server" 
desc="Redis Server" 
start() { 
        if [ -e $PIDFILE ];then 
             echo "$desc already running...." 
             exit 1 
        fi 
        echo -n $"Starting $desc: " 
        daemon $BIN/$prog $CONFIG 
        RETVAL=$? 
        echo 
        [ $RETVAL -eq 0 ] && touch /var/lock/subsys/$prog 
        return $RETVAL 
} 
stop() { 
        echo -n $"Stop $desc: " 
        killproc $prog 
        RETVAL=$? 
        echo 
        [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$prog $PIDFILE 
        return $RETVAL 
} 
restart() { 
        stop 
        start 
} 
case "$1" in 
  start) 
        start 
        ;; 
  stop) 
        stop 
        ;; 
  restart) 
        restart 
        ;; 
  condrestart) 
        [ -e /var/lock/subsys/$prog ] && restart 
        RETVAL=$? 
        ;; 
  status) 
        status $prog 
        RETVAL=$? 
        ;; 
   *) 
        echo $"Usage: $0 {start|stop|restart|condrestart|status}" 
        RETVAL=1 
esac 
exit $RETVAL

然后增加服务并开机自启动：

# chmod 755 /etc/init.d/redis 
# chkconfig --add redis 
# chkconfig --level 345 redis on 
# chkconfig --list redis
# /etc/init.d/redis restart

9. 搭建supervisor程序管理
9.1安装
系统：centos7，默认在root用户下安装，使用普通用户，可使用sudo
# yum install python-setuptools -y
# easy_install supervisor        #如果没看到报错信息，就说明安装成功了，
# echo_supervisord_conf    #查看配置详情，而后生成配置文件
# mkdir -m 755 -p /etc/supervisor/
# echo_supervisord_conf > /etc/supervisor/supervisord.conf

9.2 创建存放配置文件的目录
# mkdir -m 755 /etc/supervisor/conf.d
在主配置文件中引入配置
# vim /etc/supervisor/supervisord.conf
注释去掉
[include]
files = ./conf.d/*.ini

9.3 创建一个golang的web server
程序放在/data/mygo/ 下面
先整一个简单的golang http服务

package main
import (
    "fmt"
    "log"
    "net/http"
)
func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprintf(w, "Hello world")
    })
    err := http.ListenAndServe(":9090", nil)
    if err != nil {
        log.Fatal("ListenAndServe: ", err)
    }
}
----------------------------------------
# go build
9.4 在/etc/supervisor/conf.d下面创建go-http-server.ini
;--------------------------------------------------------
[program:yshd]
directory = /data/mygo
command= /data/mygo/yshd
user=root
process_name= yshd_game
autostart=true
autorestart=true
startretries=3
startsecs=10
stdout_logfile=/var/log/yshd_fatmouse-server.log
stdout_logfile_maxbytes=1MB
stdout_logfile_backups=10
stdout_capture_maxbytes=1MB
stderr_logfile=/var/log/yshd_fatmouse-server.log
stderr_logfile_maxbytes=1MB
stderr_logfile_backups=10
stderr_capture_maxbytes=1MB

9.5 启动supervisor服务，注意：启动服务的时候，不需要启动goweb，不然会报错
# /usr/bin/supervisord -c /etc/supervisor/supervisord.conf

9.6 查看supervisor运行状态
# supervisorctl
# supervisor>status

9.7 修改配置文件重新加载
# supervisorctl reload
# supervisorctl shutdown     #关闭supervisor
# supervisorctl restart     #重启supervisor

10. Iptables配置
 # vim /etc/sysconfig/iptables
  # Generated by iptables-save v1.4.21 on Thu Mar 31 11:36:06 2016                                             
  *filter

  COMMIT

# systemctl restart iptables.service
# iptables -L -n

11. 安装FTP
11.1 在线yum安装
# yum install vsftpd -y
11.2 修改ftp配置
# vim /etc/vsftpd/vsftpd.conf
anonymous_enable=NO
local_enable=YES
write_enable=YES
local_umask=022
anon_upload_enable=YES
anon_mkdir_write_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_file=/var/log/vsftpd.log
xferlog_std_format=NO
ftpd_banner=欢迎进入云尚互动FTP服务.
chroot_local_user=YES
local_root=/ftp
allow_writeable_chroot=yes
chroot_list_file=/etc/vsftpd/chroot_list
listen=no
listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES

11.3 新建ftp用户
# useradd -d /home/ftp -g ftp -s /bin/false ftpuser
# passwd ftpuser

11.4 需要配置防火墙，开启21端口
11.5 启动vsftpd服务
# systemctl start vsftpd
# systemctl enable vsftpd
12. 附上Nginx配置
Nginx 配置文件/usr/local/nginx/conf/
Nginx 虚拟站点配置文件 /usr/local/nginx/conf.d/
