# 服務端安裝:
## consul 安裝
#### 依賴關係：
```
yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre pcre-devel
```
#### 安裝consul：
```bash
yum install consul -y
```
#### 啓動命令(簡單啓動)：
```bash
consul agent -server -bootstrap -data-dir /tmp/consul
```
#### 查看信息：
```
consul members
```
#### 查看當前agent狀態：
```
consul info
```
#### 安裝consul web UI:
```bash
unzip consul_0.6.0_web_ui.zip
mkdir /tmp/ui
mv index.html static/ /tmp/ui/
```
#### 啓動命令:
``` bash
consul agent -server -bootstrap-expect=1 -data-dir=/tmp/consul -node=web1 -bind=0.0.0.0 -config-dir=/etc/consul.d -client 0.0.0.0 -ui-dir=/tmp/ui/
consul agent -server -bootstrap-expect=1 -data-dir=/tmp/consul -node=one1 -bind=0.0.0.0 -config-dir=/etc/consul.d -client 0.0.0.0 -ui-dir=/tmp/ui/
consul agent -server -bootstrap-expect=1 -data-dir=/tmp/consul -client 0.0.0.0 -bind=192.168.100.123 -ui-dir=/tmp/ui/ -node=server01 -dc=upstream

# 客戶端安裝:
## nginx + upsync 安裝：
#### 下載並解壓nginx-upsync：
```bash
wget https://github.com/weibocom/nginx-upsync-module/archive/master.zip
unzip master.zip
```
#### 創建upsync需要的目錄:
```BASH
mkdir -p /data/nginx/conf/servers/
chmod 777 -R /data/nginx/conf/servers/
```
#### 安裝nginx (最後一個選項很重要):
```bash
wget http://nginx.org/download/nginx-1.11.5.tar.gz
groupadd nginx
useradd -g nginx -s /sbin/nologin nginx
mkdir -p /var/tmp/nginx/client/
mkdir -p /data/nginx
tar -zxvf nginx-1.11.5.tar.gzs
./configure --prefix=/data/nginx \
--user=nginx --group=nginx \
--with-http_ssl_module \
--with-http_flv_module --with-http_stub_status_module \
--with-http_gzip_static_module --with-http_realip_module \
--http-client-body-temp-path=/var/tmp/nginx/client/ \
--http-proxy-temp-path=/var/tmp/nginx/proxy/ \

--with-pcre \
--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
--add-module=../nginx-upsync-module-master
```
